What gears exactly? Kick start gears or the actally 1st, 2nd ect gears?

Kick start gears: http://www.miniriders.com.au/motor-tutorials/25024-how-replace-broken-kickstart-gears-video.html Top work DvDRip.

The internal gears (last couple of pages): http://www.miniriders.com.au/mini-tutorials-how-s/24595-tear-down-bike-parts-completly-5.html

EDIT: won't be exactly the same but it'll be close.

You'll have to split the casing then and thats the second link. Heres anoher link to an engine split (This is too a YX 140): YX140 Engine Split

ok man yer its all split just putting it together is hard it has netrual then as soon as i tighten the bolts it loses netrual and wont click in netrual

I wouldn't know how to fix that problem Might have something to do with the gear selector? Or the gear-leaver shaft?

yer im talking to a mate on here he said to try holding the gear shifter in netrul while tightening the star and the other side of it

you shouldnt have any drama's tightening it up no matter what gear its in....
my guess is you have some shims in the wrong order or some parts are different..
another thing to watch for is the bolt on the sprocket side of the engine that holds the shift drum in place..

anyways heres an exploded view of a lifan...its not the type r but the gearbox should basically be the same
