my 4 stroke clutch has ground almost completely away.

I can't figure out why. i got it idling where the wheel doesn't move and i never ride it with the break on while the engine is revving.

I only have about 170miles on it and already needs new clutch pads.

does anyone know where i can get one or what the problem may be?, thanks.

well im running a chain not a belt, and no i'm not kidding at all sadly.

Nooo no no, I'm not riding up hills with the breaks on or anything like that at all.


Now what is strange is this happened to my last motor to before it broke from there not having enough oil in the engine, thats unrelated however and the only reason i found out about the clutch was because i took the engine apart. Then I bought another motor without a gear box and swapped it from my old motor onto my new.

Is there suppose to be any oil in the clutch or anything or some type adhesive that i missed??. I did put wd40 behind the cup on the gearbox that the clutch grabs onto using the little holes to lubricate the ball bearing witch are a little gunked up with powder from the last time the clutch got ground down on the first motor.

thanks


is it possible that the first motors clutch ground down because I was revving it with the wheel off the ground and the second one broke because it got dirty from the old gearbox being on it, old clutch powder from my other motors pads getting stuck in the new clutch?.

I used w240 to clean out my clutch and gear box and this is what came out.. http://img195.imageshack.us/gal.php?g=webcam2010091205273.png
The first pic is the gearbox the second is the clutch.


Its not oil, its dw40 mixed with clutch pad dust.

Now how could this have even happened?.. On both motors too /:..

2 different reasons maybe?. gosh... ok..

I think on the original motor it got ground down because I ran it with the wheel off the ground at a high throttle for like a total of a little less than minute and it caused the clutch to get ground down a little and thus the gearbox got clogged with clutch powder, because the gearbox was clogged with clutch powder it made the gearbox harder to spin causing even more of the clutch to get worn down until it completely ate it up.

Then when i swapped the gearbox to my second engine without cleaning it, it wore this clutch down aswell.
