Ever since then power up wheelies in first also clutch ups my chain seems to jump the sprocket. Giving this nasty clunking sound before the power picks up. Could this be caused by the front sprocket being off a little as Herbie explained in one of my earlier posts? I bought a new clutch assembly in case I have to dig into it. I'm hoping it's just the little space on the front sprocket causing it to jump. Any input would be appreciated.

I think the 17/40 is the perfect setup for street riding on the Brozz, and it seems to do pretty good with light trails too. As far as the clunking goes, mine did that if I dumped the clutch and revved it to wheelie the bike before I put the washer in place. If you do the same as I did and buy a 5/8 flat washer, then you need to go through the bin of washers at your hardware store and buy a few as they are all different on thickness by a little bit or buy a thick one and grind it down a little at a time. When I found the right one the lock just barely fit on and everything was good and tight and no more clunk. I really wished some sprocket manufacturer would come out with the proper offset sprocket for the bike. I called JT sprocket and he said they didn't have it and couldn't help me.
