What's the solution for the lower chain roller behind the footpeg? I got a Red-Racer roller and the recess wasn't deep enough and I had to grind the head off the bolt to get it to clear the brake arm and then it blew apart in 2 motos. What else works out there?

The Red Racer and OEM rollers use a recessed allen bolt that when installed is flush with the outside edge of the roller. Is this what you used? If not, I'll get you the part # for the correct one. BTW, if you are using an after-market swing arm, it will pinch the chain against the stock-sized roller. That issue is handled in a thread over on the Red Racer forum.

Couldn't source the flat allen head bolt, so had to go with the next best thing. Would be interested in bolts, tell me how to get them. I'm using a stock swingarm. I'm familiar with the fox arms and the cool extension they offered. Thanks for the info.

Go to http://www.cmsnl.com and search for part # 90124-430-700. Costs Euro 7.50. You could try http://www.westernhillshonda.com and/or http://www.powersportspro.com but I think it is a discontinued part.
