Default Re: Idler Wheel - Chinese make crappy bolts

What size chain are you using? Some of the kits come with the 410 bicycle chain. That chain can't handle the power from the engine. You may need to upgrade to a 415 chain or a z510 bmx chain. I put the z510 chain on mine and it ended my chain troubles.
