I have the Ace 160 since i got it there was intermittently a problem starting off, it was like the gearbox was binding and the engine would stall,i checked all the usual stuff....stiff chain link, brakes sticking etc.

After checking the bike there was play in the kickstart in and out, spoke to Stomp who are helping with this and they say there should not be, maybe the factory left the shim from behind the kickstart shaft stop and the case, open it up and take a look....which i did tonight, the shim is there.

Ive noticed that there is a tooth missing from the clutch basket, the basket has excessive play sideways and you can see wear maks appearing on the crank gear from this. The kickstart shaft without the case on has lots of play up and down and in/out,I didnt have a torch to hand tonight but you can just see inside a hole around the shaft on the center case, not sure if this should have a bearing or not? and the intermediate gear between the clutch basket and kickstart has lots of play too.

1.should the kickstart have play up and down with out the side case on (also knoticed there is no bearing in the case to support the kickstart)
2.should the intermediate gear have play sideways?
3.should the basket have play sideways? (the center to the clutch is ok with no play)
4.it will need a full strip down now too to find the missing tooth

Sorry Prox but I know nothing that can help with your issue.

I just wanna say I am a YX160 owner and I really like it.
I put an OKO on it and a better CDI and thats it. It flies for what it is!
Great motor.
