I know it is due to do, and last time I took it in for a 'warranty' valve clearance, I was charged around $200 US and I had to leave it for the night so that it was cold when they did it. I did so and after 3 hours on buses (transfers, getting home and then going back to pick it up), what are the tools necessary to do a Valve Adjustment?
Side note: This place also charged me almost $100 for an oil change that took over an hour. Now that I am no longer in the warranty (almost a year now) and I do it myself, last week I changed my gear oil, motor oil, and cleaned my carburetor within an hour and only $12 in material (bought oil, but have plenty of gear oil in stock as well as carb cleaner spray).
I have an Agility 50, 2009 with around 15,000 km. Used daily and basically a new belt, but I am missing a slider in the variator, which is on order (realized it was missing on last belt change).
I have no idea on how to do a valve adjustment and/or what valves need adjusting. I can take my scoot apart, but really I have only dealt the carb, belt, rollers and changed some light bulbs.
Any advice on what tools I need or let me know the 'experience level' that I need to DIY it would be great. If I need to take it in to someone I will, but if this is something I can do myself, I would rather do that.
Thanks

There is a link to a service manual in a thread called "links to manuals" in the general section. It is REAL easy to do.
Scooter How-To : GY6 Valve Adjustment (Also For Buggy + Kart) (http://www.youtube.com/watch?v=s0K-ytyjOFg#)
For 100.00 yuo can buy all the tools you need to rebuild any gy6 engine.
Your mechanic was a bit pricey but he most likely lost money on shop costs for the day. You gotta think about that too. Utube is full of vids on every part of your engine. Forget about hurting the shiny body. It's just plastic.

I forgot to quote Mary K... "hit it with a mallet."
-
Yup, its easy. I held off doing mine for ages cos i was chicken i'd make a mistake and wreck my engine but it was simple and quick to do. Just wat h a few vids and read up on it 1st so you are sure you know how to do it. And be certain you use the correct size feeler gauge.
-
Thanks Zombie for the proper vid, that is totally different than what I thought a valve adjustment was going to be. I don't mean to knock the dealership people, I know they have to make money to stay open and I am sure the overhead is crazy high on a scoot shop, just sometimes that sticker shock really gets to you.
Yep, by watching, I feel totally comfortable. I have a complete set of wrenches and other tools, so I guess all i need to pick up is a feeler gauge. Sweet, thanks again guys.

There should be a thin rubber seal round the cover so just make sure you fit it back in correctly so you dont have any oil leaks. Mine was missing when i 1st did mine (no i didnt lose it, it just wasnt there), think the previous owner had mislaid it somewhere in the past so i just bought a new one.
-
That's why were here Bro!

black seal a gasket well work for this.

You're right Zombie, these mechanical stuff is very easy to do. But the problem of these Kymcos (I don't know about others) is the difficulty of removing and worse assembling back these plastic panels. I had a Chinese ride before and you just to find the screws or bolts, take them out, plastic panels pops out, then whalla!! you're in! To put them back, just do the reverse. With the Kymco, I have to study the leg bone which is connected to the knee bone connected to the thigh bone connected to the hip bone .... and before you know it, it's dinner time again!

I've glassed all mine into three pieces total for the scoot, and 2 for the head set. My body is off in 1 minute
-
I finally did my first Valve Adjustment/Clearance and I must say I did it within an hour.
So, I bought some feeler gauges I couldn't get the .004 inch to fit on either, so loosened them tightened them down to the .004 and tried the .005 to make sure it wasn't to loose, however, now I notice a very rapid tapping sound.
I know the scoot needs to be cold, so there is no need for me to open it back up and look at it for a few hours or until morning, so thought I would post for thoughts. Maybe that tapping was always there, it is just since I was over focusing on the one part I noticed it allot more. Hmmmm?
-
You set the gaps too small :P
It should be set to .04mm not 0.004" (0.004" is only 0.0015mm :o )
So yes you willneed to open her back up im afraid :(
You learned at least how to do it so it should take you half the time.
-
So, I have the gap to big then. I am looking on my feeler gauges and I have a .038mm/.0015" feeler. The other one is .102mm/.004", the one I used today. That is why when I did the test when I first opened it up and tried to fit the .004" one in there it wouldn't fit. I was like, oh, that really got tight, but really it is suppose to be tighter. Thanks bud - will do it in the AM and let ya know.
-
Yeah the .038mm/.0015" feeler is just under but it should be fine. Youre right, if you set at 0.102mm its too big a gap, more than double.
You'll be an expert at it now at least :)
-
i think blue said to me that you can set the valves at 0.04 top 0.03 bottom. "try it you will like it"
-
..i just set valve clearance on an un-touched 2006 a50 with 4800 miles onnit...
..checked before adjustments, and they were at .102mm...
..set intake to .04mm and exhaust to .038....
..with unrestricted cdi and boss, scoot runs 45-50 flat out...
:o
-
valve works best at ,04 exhaust at .02

valve works best at ,04 exhaust at .02
..blue drops a bomb....
;D

hang on is that the same measument you gave me? im gonna get Mr Dave to reset my valve clearences after i get all my engine bits.
-
Whelp, after I did the clearance last night, scoot started and I heard the tapping. Now that I have re-done the clearance, since I did it wrong yesterday, the scoot won't start now.
I am going to re-do it one more time, but the battery and spark are fine and when I hit the start button all I hear is a single click and then nothing.
Any ideas on what I messed up, biting nails over hear, I have an appoint down the road at 3pm, need to get her running.
Clicking noise is coming from around the gas tank.
-
I re-did everything and then I used a string to keep back brake engaged so I could hit start with one hand and use the other to feel around, looking for clicking noise. I moved a wire (to the bystarter) and it started right up. Does this mean my bystarter is bad then or do I have a short?
Thanks guys, yes valve adjustment was pretty easy, been a fraidy cat to do it myself. Thanks for the info and encouragement. Oh, I just did both valves @ .038mm, no tapping noises now.
-
Its prob just been a bad connection on one of the wires, when you moved tbe qire its remade the comnection, either be down to corrosion or dirt prob.
You can take off the wires and make sure theyre clean and tight, if its working now i'd leave it but remember what this issue was in case you have the same prob again, then you can check there 1st.
Its all easy once you did it a few times, just teething troubles. Think of the satisfaction of doing it all yourself and the money you saved and will save in the long run with servicing etc. :)
Been there, done that, with the whole "why the f..k did i even touch it" thought a few times myself in the past :D
-
Bystarter meaning the starter relay? There are four wires. One is to the push button start, one is to ground, one is to the starter motor, and one is to the battery. I would check all four for a loose/dirty connection. If they are all in good shape simply replace the relay wiyh one of these relays.

either be down to corrosion or dirt prob.
x2 I had my scoot tore down a few weeks ago.and found so many wires that had corrosion on theam.
Im lucky scoot would start. I took my time and cleaned almost evey part of the wireing. makes a big dif.
