hi , i searched all over the internet but i did not find :
- original BELT SIZE for agility 50 (i have no chance finding the original belt to buy)
i intend going for malossi kevlar or dayco (if i can find)
i have the original belt since new and now i have 8700 km on the clock
- original air filter (from paper) so i want to cut the paper from the old one and fit same filter paper in there. I`m not sure how to glue it there, maybe silicon ?
i "cleaned" it twice with jet of air but it`s to dirty now
I want to change the belt because i feel some vibrations when i take off and i think that`s the problem. Am i right ? I heard i also have to clean the Clutch from it`s own dust (i can`t express myself) because they cand make the clutch slipp and => vibrations again
so please

..go to stadiumyamaha.com
..they have the belt, air filter etc...
..with only 8700km, your belt is probably fine..
..the dirty air filter could contribute to the vibration, i've had that same thing happen once before..
..where are you located mikrron?

At 9'000k It may be the rollers more than the clutch/belt. You can tear down all the cvt parts, and inspect the rollers for flat spots, clean the clutch w/ DE-natured alcohol, and measure the widest area of the belt, (across the top). Then you will know for sure what is needed. If you need help ordering parts there are lots of people here willing to drop ship an order for you. http://www.stadiumyamaha.com/pages/parts/viewbybrand/default.aspx (http://www.stadiumyamaha.com/pages/parts/viewbybrand/default.aspx)

nice site, i will register to see the shipping costs to Romania Bucharest
I have found belt. here an OEM belt is 66$ (double the price from the site) while malossi kevlar is 33$
I have changed the rollers at ~5000km with 5g ones hmm but i`m going to take a look inside and measure the belt too (min 16,5 width)
Thanks for the site :-*
PS shipping costs are way to high for my location from 36$ (product price) to 110$ (final price)
but it`s good to know in case something important brakes

Like I said Bro, Both myself, and some others here would be more than happy to order parts, and ship them for you at no extra cost. I will ask at the post office today to give you an idea!
-
i measured the belt width and it`s ~13,5mm. Service limit says 16,5mm measurement error
i also found out an abnormal movement: i held the variator and pushed it then pulled it twoards me. it moves a little :o. but i has no up-down movement. i think this ax moves on the bearings. and it`s a well driven scooter..i`m starting to hate it

..when you say "a little", the crankshaft will move a few mm in and out...that's normal...
..sounds like you need a new belt tho...

If the crank shaft is moving side to side you will be able to se this by holding the fan on the opposite side. It really should NOT move. If it does the bearings may be worn. As you posted at first , Have you tried to remove the clutch bell to clean inside it? A little de-natured alcohol, and some FINE 600grit sandpaper too remove the shine. Is this a two stroke or four stroke AG.?

I just checked 2 engines in the "shop" and the one on my ride, and 0 play on all three! Maybe your var is moving. The crank should be rock solid. Its all pressed together, and the ONLY play is if the bearings/races are worn. Re-check yours slinger.

..i'm sure...i can move it in and out by holding onto the splined section of the shaft..have been able to since the first time i was in my cvt, when i installed the malossi...

the scooter is stationary till i buy all the parts so i can mount them and inspect/repair/clean the rest of the scooter. so i will check my crack shaft and clean the clutch then.
But i`m pretty sure it slides with the ax (2-3mm) and makes a tac sound. this is not normal. otherwise the engine runs great no noises! Wish i haven`t inspected it.
the oil was changed every ~2000km , not abused, it has 30km/h break in.
as wordslinger says (and hope he is right) i will check other scooters at scuter-centre too ..you never know....
it`s 4 stroke agility 2006
i will fit 72cc kit, fresh air filter, malossi belt and multivar 2000 probably with heavier rollers
next month!
thank you very much

i`ve inspected the fan side 1 minute ago to see better and the sliding is rather 1mm than 2-3mm. I`ve exagerated with 2-3mm earlier.
so if wordslinger is right i may hit 44.000k with no problem :)

hello guys , bouth me and mikrron have a strange sound which it seems to come from fan ,do you have any ideea what could it be ?
strange sound from agility50 (http://www.youtube.com/watch?v=Vsec69zT6Yw#lq-lq2-hq)
here is a video with my scoot ...

The stock fans are made of a Nylon type material that tends to crack over time. My stock fan had dozens of them. There may be a loose blade due to one breaking at 1 end, or as sdithesloth found you may be hearinr the rollers "echo" thru the flywheel, as the cvt cover shields most of the roller noise. Easiest way to find out is, Remove the plastics, cvt cover, and the engine shroud. Make sure the jack shaft for the kick start is either removed, or held in place so as not to fall out, and start the engine. You will be able to see any broken blades on the fan, and hear where any noises are coming from. Could also be some debris in the shroud near the fan. Either way taking it all apart is the best way to inspect everything.

Hey by the way mikrron, I took a ball park guess you were somewhere near Romania! To ship a 6lb. package from Florida, it would cost $43.00, and that has $79.99 worth of insurance built in. Most places I order have free shipping to my door so If the #'s help let me know...
-
hope it not your crank. mine did that and I found out the crank was bent not good .
take the fan cover off and run the scoot like that for a few and see if the sound goes away.
maybe a stone or something in the fan,
-
ok zombie i`ll keep that in mind for expensive parts, it doesen`t make any sense otherwise. i`ll buy belt and air filter from here. Air filter is 15$
but kymco rarely brakes down.
i noticed that sound coming from the fan only from kymco scooters. baotian sounds so nice >:(
i`m going to take off the cover and start it like that, then start it without the white fan
back from the scooter.
the sound seems to come from inside (bearing or ax) maybe echo as someone mentioned, not so loud as in the video.
Don`t care anymore. I`ll run it hard from now even if it`s going tu f*** itself up!

From the first day I had mine it has what sounds like a rattle in the engine. I had some rags stuffed around the exhaust header for cleaning, and noticed the rattle was gone. Turned out the rattle was just the pipe resonating at a certain rpm. If the bearings are worn/bad you can feel that by spinning the engine by hand w/ the spark plug removed.
