I installed a JB swingarm on my YFZ with a RPM tapered bearing carrier and dominator 2 axle. It seems as though the chain doesn't line up, my chain is rubbing against my chain guide and the master link broke off when I was riding it. Has anyone else had problems with this? or did I just get a bad swingarm?

It must really be off alot. On my 400ex I had a walsh swingarm, which rubed the chain guide with the chain. It just made the chain shinny on that side and wore the plastic in the chain guide. Never ever had a problem though, I think the chain guide is worth its weight in gold. I never threw a chain.

I looked at it a little more tonight, it seems that my chain is worn more than I thought, it had some pretty bad side to side movement to it. It looks like the chain had been slapping against the PEP roller mount, it might have caught the chain and busted the master link. It still looks like the alignment is off though.
