Title: Oil in water xciting 500
Post by: xsel777 on August 07, 2018, 09:38:26 AM
I have found oil in the water in the filler pipe.
Very thick.
About 3cm length filled with oil.

Over a two week period this build up.
A week later I checked again.
2cm length of oil in that pipe.
Oil rises, so that is why it is at the top.

Only two places that I know where it can come from.
Mechanical seal, but I see no leaks on the outside.
So that probably means it is ok.
You have any other views on this position.?

The most likely is the head gasket or a cracked head.

The gasket has been changed a few times (while replacing exhaust cam)

The head had been skimmed once.

What are the chances of it just being the gasket.?
And not worse.

I was talking to someone who seems knowledgable regarding mechanical things, and  the oil cooler came up as a possible suspect.
Why?
Because I must continually refill oil, 250ml at a time, and exhaust its not wet. And this oil in water symptom described in this thread. Is this a credible possibility?

When sitting on the scoot, it is on the lower left front of the engine.
The  oil and water pump are on the right hand side of the engine

What I find each week, when I open up the filler cap.
I just take the filler pipe off, blow it out and refit. Once new distilled water is in, and I run the motor, the now green water gurgles away just fine.

I am going to get a used oil cooler and see if the situation changes. It is the cheapest and easiest option, and also it is one thing that had never been changed in all the times it has been in the workshop.

Update : the scoot is at the mechanic after I did a radiator flush and cleaned the pipes, and now the motor is on the floor and the head is off.
According to the mackie, all looks ok mostly, just a little bit black, from fuel injection he says. Nothing wrong with the exhaust cam, so that concern is sorted.
The new head gasket is black, but the old one is gold.
The head has been declared straight. No leak found there.
So, I told them to leak test the oil cooler, because there can only be one other spot where it could leak oil into the water , the mechanical seal at the water pump.

They don't want to  take off the barrel, as the refitting of the rings is considered risky, possibly resulting in smoke.
Since there is a gasket there too, perhaps I should push for checking for a oil leak there?
This is my only question.
But feel free to comment on any thing in this post.

I have supplied replacement coolant pipes, and await a report of where the leak is coming from. Much Head scratching!

Ok, I have had the scoot for the afternoon, and it drives ok. They did not change one coolant pipe, top radiator. It is to much hassle to go back and moan. I will sort it out. Tappets are noisier. They can reset that when the head is tightened at 1000km(the first time I shall be doing that).
I was given instructions to watch for a reaccurance of the issue, since there was not conclusive evidence that the head gasket  was the actual weak point. So, the oil cooler is still possibly the culprit.
Luckily, the Kymco scrapyard, has a xc500 with an oil cooler, so, there is hope yet.
Never give up!

Yep, I am getting all and sundry advising the same, but this is the issue, no cash for a big purchase, each large scooter, like burgman, tmax, sym, are through the roof expensive, and even more expensive to service. Eventually it is expected that all the issues will be sorted, and I can relax regarding the reliability of this scoot.
I am quite happy to have it back, as that kymco super 8 is so slow I thought I could walk faster.
On the other hand, I am out of funds so I am riding slower and slower, in the hope it will not break again.
A thing that has improved is the temp is behaving like it should now, and not temperamental like it was before.
Onwards, we go.

I don't think it's the sort of thing where driving it faster is going to make anything worse. Either you fixed the problem and you can drive it as hard as you like. Or there's still a leak somewhere, and driving it harder isn't going to make anything worse.

Are used Burgman 400's expensive down there?
Burgmans don't have much resale value here in the States....certainly not when compared to their MSRP OTD price!
Other than valve adjustments, which few do, they are easy to service....and pretty robust by reputation
In any event ....best of luck with your current ride!

Chinese scoots on every corner, but the high quality stuff is scarce, and consequently, people hold onto them, and correspondingly, the resale price stays high.
I actuality saw a skywave(original name for Burgman) at the bike shop, and the mechanic said mine was a breeze to work on compared to that.

Hypophthalmus, the leak issue is a fairly recent thing;I was referring to the 4 exhaust cams I have had to replace previously, and this as a recurring theme, is not something I want to see anytime soon.

Then there is me, over torquing first the rear axle and then the crankshaft nuts, stripping the threads, requiring replacement, so now, I just ride, and won't be opening that CVT for a long while.

These things are sent to test us, some more than others, and my character is so nicely sharpened from all this "duck off a waters back" , I practically shine as I walk down the street, 😁.

Possibly you shouldn't be thinking of the Chinese scooters as lower quality?

I still find oil in the water. One mechanic says he has never ever seen a warped motorcycle head in his 30 years, and is adament it is the waterpump mechanical seal, there is another seal behind it, in the oil side, that could fail.His workshop is full if big bikes.
The other mechanic says he has seen a warped head before (20 years in business) and he says that if the leak Hole does not drip on the water pump, then there is no issue there. He does not have xciting 500 experience, mainly 150cc.
I don't know which way to turn now.
The local importer is gone, so I have to import the parts myself now.

Some of the first Honda Forza 300's had an issue with the same seals being cut on installations by a burr on the cover. Caused the same problems. Many were recalled under warranty.
My point is, could very well be the seal.

They already physically measured the head, didn't they?

The other option would be the oil cooler, right?

The water pump seal sounds more likely to wear to me.

Post by: xsel777 on September 26, 2018, 05:39:20 AM
The testing of the head was somewhat unconventional. He is not a fly by night biz, as he services the local traffic dept bikes, and I see bikers arriving with shiny 1800's and so on, so if he was useless they would not trust him with their prescious bikes. He went into a dark room, and using a steel ruler, checked if any light was coming through. None he says. Then he also used grease and a piece of glass, and said that test also confirmed to him that the head was not warped.

The scooter has Finally given up the ghost.

It suddenly would not idle, then white smoke from exhaust.

And then stopped.

It is at the workshop now.

But....

The old Kymco importer sold out to Yamaha in Dec, 2018.

Sounds great right?
WRONG!
Yamaha has no infrastructure in place, and no stock.
Everything is on back order from Taiwan.

Even a local dealer who used to be agent, said to give up on Yamaha, as he has items on back order and still waiting.

So, I ordered from eBay, gasket and air filter.

Maybe a two month wait, but hopefully sooner.

The scoot overheated a few times, and finally, I broke the sparkplug in the head, probably due to overtightening, but where it broke is strange, at the top of the threaded metal part.

Laying in a dark corner, in a fetal position.

I got all excited when I thought your scoot had finally put YOU out if its misery!
But no, it seems it's just in the Emergency Room again....

You, or the scoot in the fetal position?

No one could fault you if you were to give up on that 500 of yours.
Maybe a trial separation - where you see each other on facebook - and once a year for coffee = and you could see other scooters, that work ,again?

I got a quote for a copper head gasket, and was surprised to find I did not have to take out another mortgage to pay for it. Lasercutting. They will do the autocad drawing from my sample. I must just supply the copper sheet.
Maybe that is what the cost is?

Never give up.

I keep hearing "get a new scoot".
Naysayers, bah!

After week, the shop finally stripped the engine, and it looks like just the gasket.
There is no obvious crack, and the valves are deep, so a skim will be just fine, as the copper gasket can compensate.

So very relieved.

I have left the dark corner, and might soon be seen dancing.... [emoji3].

Ok Folks, something is beginning to happen here at last.

The head and barrel came back from the engineers, but the barrel had to be returned, as they said it was fine , but mechanic said not so, and when it was returned the second time it had 0.3mm milled off!
The head got a 0.06mm shave.

I am going to get a copper gasket made, but the barrel/cylinder skim exceeded the warpage allowed. (0.05mm)
 
The mechanic suggests adding that 0.05 to the barrel gasket(at the bottom, which will put the top of the barrel at the correct height for the head gasket.
Then the copper gasket only needs to be 0.06mm thicker than stock.

Workable?

Head max warpage is also 0.05mm, so skim of 0.03mm is within spec on this part.




That was part one of the story.


Part two is :

I need to know what the uncompressed thickness of the stock head gasket for a kymco xciting 500 Ri 2010 is.
I have a manual but I only see working clearances for the metal engine parts, not for gaskets.


How can I get this info, or can you assist?

I spoke to the local ex kymco agent, who I am on friendly terms with, and he indicated that the two copper gasket idea is best.

But even as an agent, he can't provide a thickness for the head gasket.

I have not been able to get any info on the thickness of the original new head gasket.
I am now waiting for the one from the post office (paid for already - so preferred), and /or the other one from Yamaha.
When I picked up an original air filter from Yamaha the other day (a pre-order), I was advised that he is waiting for corporate Taiwan to respond to my request.

And that is where we stand.
Can't move forward until I have an accurate measurement.

Well folks, some news on this ongoing saga.

The original gasket arrived from Italy, and a copper copy will be made(in the process)

This is the situation :
. 36mm material was shaved off.

I could not find an exact thickness of copper sheeting, and engineering the thickness seems to be problematic and not very accurate(according to one engineering company)
I can get  .8mm ,  1mm and 1.5mm.

During discussions with the bike shop, the barrel gasket split apart into two gaskets while handling and measuring its thickness.

gasket thickness for reference:
head=0.8mm at inner cylinder edge(thickest)
barrel=0.5mm

I checked with two bike shops, and they both stated that the barrel would only have one gasket, so the extra gasket was a mistake by the shipper(Kymco)

cool, right?

It is cool because that takes care of           0.25mm,leaving 0.11mm still to be covered.

According to the bike shops(2),the copper will expand when it is annealed.
I cant get figures on degree of expansion, but it at least whittles away at that 0.11mm

Furthermore,the mechanic where my bike is , and the other shop(where I am double checking everything), both are of the opinion that 0.11mm will still be workable in that no valves will hit the piston. The piston does have valve recesses.
The compression will increase slightly.

That last sentence does concern me, as these 500's do battle to start in the cold, but I have actually got that problem sorted, but still, I am still concerned.

So now, the decisions have been made, and it is just to wait to see what happens on assembly.

No, I am not buying another bike.
I might consider a new barrel if I don't have to sell my house to get it.

My stomach is all in knots whether this work out.

Well, the tension is really picking up now.... 😀.
The shop is actually working on the scoot!
And winter has started with the first storm.
That plug I broke off, was so easy to take out, it was embarrassing.
The motor is on the bench, and testing piston and valves are not touching before final assembly.
I can't wait.

It was so close, but not to be.....
No, I don't mean the bike is toast, [emoji16].

The engine was put together today, and the valves were not touching the piston, so all was going well, until it was found that a bolt was not tightening properly.
A very long bolt from the rockers through the head, and also down the side of  the barrel, into the engine case.
It was pointed out to me that this was on the same side where the old head gasket had blown.
So a helicoil will be fitted, causing a delay.
Darn, I was hoping to be riding this weekend.

I suppose in a way, this is actually good news, because for the first time, there is actually a definitive cause for why there was oil in the water, and all the swopped out parts had not resolved it(and with nothing else to swop, leaving the question, "what is going on here?" ).

So close, so close!
one more day only, hopefully.

At the workshop my scoot was started today.
The mechanic had to fit a helicoil kind of thing into the engine body where a bolt had stripped.
He showed me how the temp was now lower than it used to be, than ever before.
Previously, the needle was in the middle, but now can definately be seen to be below the middle line.

The mechanic was unhappy with the exhaust front piece glowing red when revving up to about 4500-5000rpm.
He was saying that it should not do that, the bike is running too lean and this is probably why the heater on the O2 sensor had broken (twice).

So, I ran my Chinese engine code reader on it, It can reset codes and adjust co2 levels.

Now the questions :
Is the mechanic right or wrong about the red hot exhaust pipe where it comes out of the engine?
And about the heater on the O2 sensor dying twice?

lastly, The co2 levels.
Nodody at that workshop could say whether the adjusting + or - from the default 0.0 was the correct way to go.
Another way to say it ; does adjusting co2 level from 0.0 to 1.5 mean more oxygen, or more fuel,and the same with -, going from 0.0 to -3.0 mean less oxygen or less fuel?

The mechanic said I must get a CR9 plug, because the exhaust is getting so hot.
Your views.?

Oh well, it was not to be.
The rear brake caliper was replaced(I had one that I imported from usa refurbished), but then the master cylinder was found to be not producing adequate pressure, and the brake handle was worn down.
I even helped a bit, I order to get the bike done for the weekend (a long weekend) , but, it was not to be.
Anyway, I do have good news, the owner of this workshop has a 500 gathering dust in the back, that cant start due to starter motor breaking a part of the casing.
My O2 sensor is faulty, the heater, and after a conversation with said owner, the result is  I got one for free.

It was ready for collection, but then........

The rear brakes were very spongy after fitting the refurbished caliper.
First round failed to get a decent pressure.
Second round was better, but still not  satisfactory.
Third round, pressure was aquired, but then the braided hose sprung a leak.
My handlebars are bare metal, and the brake hoses have been rusting.

I was told I must replace the complete length from cylinder to caliper, as it is one piece, but I am almost certain that there is a splitter under the fairing, so luckily it will be a much cheaper replacement.
In fact I have some hoses from the Kymco 250 I used to have, so the fix will be free if the hose is not too long.

Here's hoping.
Wish me luck.

It turns out, there is a brake splitter on the 500,but it is for the front dual brakes only.
I was getting confused with my grand dink 250.
So, price for a new made up hose, is horrendous, but, they work really fast, and so it is fitted and now just waiting for a call to say the scoot is ready for collection.

Hey good people.
I rode it for 1km and it overheated.
I waited 5 min, and carried on.
Starting was difficult.

I got it home.
3km ride .
Stripped off the plastic.
Took off the radiator cap.
no water to be seen.
I put 500ml antifreeze in(half a bottle).
Started.
Antifreeze blew out the inlet pipe like a volcano eruption!
I refilled, emptied the antifreeze bottle.
restarted. with difficulty.
Noted white smoke from exhaust.
Turned off engine.
refilled radiator as the level had dropped again.
cap on, attempted restart, and the overflow tank overflow pipe spewed antifreeze.

At this point, the conclusion is conclusive ;
crap job.

I am disappointed, but cant go there to express it fully.
I will talk to God about it instead.

So, back to the workshop  it goes.

Thanks CROSSBOLT.


BTW, the brakes are fine...... :)

mousejunks, me too.
I can secure a complete 500 for a fairly reasonable price, a carb version, 2007-2009 abouts.
The crank is gone and cost of replacement is more than the scoot is worth.
If the crank is so much, I can only imagine what the barrel and head will cost.
So, a potential idea is to swop out what I need to get mine going.
I don't really want to  go this route, but the advantage is I will have plenty of spares(but nothing EFI related).
I actually am at the end, because the exchange rate is crazy(14.5 : 1),and now that Yamaha is the agent, the prices went crazy too....
I cannot buy on credit, through the bank, as my business has very erratic cash flow, so the banks will balk.
I think this; I have never tried, as I see my bank balance, and I would not risk me.
All stock that is available is of the Chinese variety, and I would rather walk than get one of those.
Anything that is higher than 150,and not Chinese, has a premium here.
I have been looking for divine intervention/assistance, because it is all getting beyond me.
Not giving up though, just outlining the situation, as I see it.

Well, I went around to the workshop, and the consensus is that it is the head bolts are stretched.

Yeah, if you had TTY head bolts they are one-time-use only.
I guess that big 500 pot could stretch a headbolt. Thought only iron car engines could do that?
In any event.....I could be your agent if you decide to do a NETFLIX series.
Seriously,  best of luck with this.

I think they stretched because the head has been off about 6-8 times during the time I have owned this scoot.

We are looking for extras, particularly favouring those who can laugh like hyenas!

According to the mechanic he has fitted new head bolts.
Engine is back together.
Still to do:
clean out coolant system (oily), and test drive, but not just around the block, a bit further.

Tomorrow is D-day, because finally it is sorted. Speaking positively.

At least today it did not overheat, when I fetched it ; in fact I never got out of the parking lot, as it would not start.
If it struggles to start, could be compression leak again, or some other issue.
This time no coolant spewing out of the expansion tank overflow pipe.

So possibly compression leak small, like before I brought it in for repairs, or some other issue.

They did not use the original gasket, just the copper one, so they must be confident it is working.

It did drive fine during the test ride.

Ph well, Netflix weekend then.

I can't expend any further emotional energy on this, it is a soapy, without the torrid love triangle.......[emoji3].

Possibility I will be riding tomorrow, although I am concerned about one thing.

There was no spark, after a test ride, and the shop rerouted wires/made new wires , tested the ignition, replaced coils, and drained 8 batteries and the charger,
until....
I rocked up with a new Motobatt MBYZ16HD and an iridium Cr8eix plug.

all good it seems.

Just to put the plastic back on, test it and clean it, for pickup tomorrow.

Here is my concern :
The bike was cold, it had not started since Friday.
I undid the radiator cap, and liquid started squirting out under pressure.
My experience has been, that once it is cold, the pressure reduces, so it is easy and safe to remove the cap.

I asked the new mechanic if he was confident that the head  gasket was now properly secure with the new head bolts, and he assured me it was.

Your view on my concern, or am I just being too jittery after all the issues I have faced here, feeling somewhat traumatised.

Well, I got it back.
Things noticed : appears 6 month old waterpump is leaking, green liquid.
Upon closer examination it is a water pipe above the pump,these pipes are not in good shape, as they have had oil flowing in them for awhile.
When bike has cooled down I will sort that out.
Engine light is on, so I am assuming is due to them working on the bike.
To be noted is that two previous O2 sensor heaters have blown, engine light comes on then.
I have a Chinese OBD computer checker.
I will check that out too.

Update to follow.

Yep, and for that I am very grateful (no Netflix ads).
Now the talk is about using the original head gasket.
I have voiced the opinion that the engineers messed up, as there is no other place I can think of that works be causing white smoke from exhaust except combustible chamber area.
The head does not have water channels, as far as I know, so only at the gasket area where coolant can be introduced into the exhaust causing white smoke.
I wonder what is on netflix?

Well Folks. I am on the road again.
However......
lol, you didn't think it a going to be that easy right?


It is smoking heavily.
Since I got it back, yesturday, I have had to put 1.5l oil in.
There were actual smoke rings leaving the exhaust when revving on the stand.

I am disappointed that the shop did not investigate the smoke which I mentioned three times,Each time it came back from the shop. I did say it was white smoke though.
Still it still warranted investigation.
And the shop owner has mentioned twice now that there is potential for smoking if the barrel is removed.

Luckily now, Yamaha, the new agents actually have spares in Durban, 1700km away.

So, now I am riding with a litre of oil in the top box.

What is right :
Starts first time.
No coolant leaking or spewing out.
Temp stays at half.
No engine light(newish O2 sensor)
Original gasket seems to have done the job.
I wonder if it is because it has that thick bulge around the cylinder hole, which the copper gasket did not.
The scooter is raring to go fast. I can feel it definately has got the power back.
Higher compression is the reason.

Ok, I have just paid for rings, another head gasket, tappet cover gasket. 2 days eta.

I tried to complain but it was waved aside, I don't think I was heard.

Very disappointed.

The new mechanic says he just needs to hone the cylinder, and regular size rings will be fine.
The excessive smoke can only be coming via the rings he says.

This thing has reached a point where it is no longer about the money, but about my peace.
I saw milky green antifreeze coolant in the return pipe(right under the filler cap), so it is starting  again.

I cannot comprehend what the actual issue is, because the head and barrel were skimmed, the copper gasket showed a coolant leak. Now the original gasket is showing an oil into coolant leak.

How can this be happening on an ongoing basis.?
It makes zero sense.
I know they are trying their best.

Apologies re the rant.
There is no other platform I can let rip, as in nobody else in my circle is mechanically  inclined, so I just get blank stares, and from my wife, daggers, because this dang scooter is no joy.

It IS terrifically aggravating not to have a reliable daily ride.
Goodness, you have tried so hard!
Makes me embarrassed to be upset again this morning about my LIKE's one mirror that won't stay in place. All 4 of my scooters have been bullet proof (or made so after just one warranty fix)
Can't imagine constantly having to approach my scooter and wondering if it will work this time....especially after so many repair attempts.

We're all pulling for you!...but you know that.

Righto, this is the situation currently:
New oil  rings were rattling around in their slot.
Verdict was piston is worn.
So that is now ordered.

It is confirmed that no oil leaked in to the coolant.
Very good
Very VERY good!
The oil was found on top of the piston.

However, there are hammer marks on the upper face of the barrel.

I told the owner I am not happy about this as that is not how it came back from the engineers.
He would not take responsibility or acknowledge any wrongdoing , and just stated he will double check it later.

I took photos.

Amazingly, the piston arrived overnight.
I hurried over to the "mechanics", and got them to fit the new oil rings to the new piston, and they did that and it looked tight, and then they showed me how secure it was in the barrel, so that looks like it could mean that the high oil usage is sorted.

I left feeling somewhat reassured.

I might be riding this weekend.

I got so fed up, for awhile I stopped going over to the workshop to check on progress.

Anyways, I went over yesturday, and the scoot was out on a test run, no white smoke from exhaust (a good thing), but evaporating steam from coolant pipes splitting, this time above the oil cooler.

Today they are out searching for coolant pipes they can use to replace mine which are all weak from all the oil that has been flowing in them.

In the meanwhile more helicoils had to be used, as the engine had been disassembled so many times, I suspect  every thread now.


That's all for now.

I got it back today.

What has transpired.

On the test run, the right mirror blew off.
It appears to have had a stress crack that finally gave way, evidenced by a darker colour(dirt) over most of the surface and a smaller white area where it finally gave in.

Anyways, that does  not faze me at all.

I had to go look for generic hoses, all the thin diameter ones as they are bursting all the time now.

While searching motor spare shops, a pipe burst and all the coolant escaped. I drove off the highway, 200m about, and then pushed it home.

I replaced all the perished hoses, and filled up with coolant, almost 2l.

Ran until hot, and noted oil residue in the filler neck.

No white smoke from exhaust.

I took it for a test run, and when stopping abruptly when I got to my drive way, the oil light came on momentarily.

I will check oil levels tomorrow, and take it for a long ride to see if the oil accumulates in the filler neck again.

oh boy.

Have a good week end folks.

After test drives up the freeway, a miss that I had noticed when revving while on the centre stand, suddenly became extremely apparent when it started with cutting/missing out at 130kmh and above.

When I got to a stop sign, there was massive surging  from 2000-3500, making the scooter unsafe to drive.

Workshop will collect it soon.

I went over there and mentioned that hammer indentations on the barrel (by the area where the oil is exiting and pooling on to of the engine) is not the condition the barrel was brought in, as well the previously mentioned, the hammer marks on the gasket surface, was not the condition after returning from the engineers.
I asked if this warrants me shouting in frustration, if I have valid points, or am I just a stupid customer.
This produced some  throat clearing only.

Mentioning the same issues to the mechanic produced a "deer caught in the headlights" look.

I think I shall watch some online tutorials that can improve my IT skills.

Keep well all.

I am probably going to sell it to the workshop owner, as he has on old one there he needs spares for.
Mine has a new crank, new axle, Malossi sports variator, sports clutch spring, bigger givi screen, hand guards, backrest.

I have been looking into a tmax.
two options available in my area :
2009 500cc XP500 15000km
2014 530cc               80000km

I want to  go for the one that will be less maintenance cost.

yep, it has been a circus, but is likely time to give up on it.
I checked with a car salesman when I was there today working on his pc, and he said that I can get a bike on credit on my business account if I produce 6 month back statements showing movement through the account.

So, beginning to feel lucky.

Hey folks

The nightmare is finally over.

I gave it everything I've got, but was ultimately unsuccessful with a definitive repair.

The workshop is buying it from me.
I enticed him with a obd reader, and free spares(what good are they to me now? ).

And I signed on the dotted line for a 2009 Yamaha Tmax with only 15000km.

I am so glad I held on  tight because the acceleration is awesome!..... [emoji3].

Interesting thread.  I just picked up a project 2007 Xciting 500.  Wasn't running but got it running and same thing as you.  Blowing white smoke and leaks coolant, thinking being over-pressurized by the cylinder leak.  Bummer you never got it resolved.
