Oil in water xciting 500

[xsel777]

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, 😁.

I had no idea that the xciting 500 had that sort of cam problem. That's ridiculous.

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.

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.

Oil cooler has been ruled out with a test confirming no oil in the cooler water channels.

Oil still in water.
2 mechanics for water pump.
1 mechanic against.
So yesturday I replaced the water pump. I must still flush the system again, and then we will see what happens  next.

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?

Whatta guy!

Gotta laugh, hey?
In any event, I ran out of tears a long time ago.

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].
