A new chain cured my surging problem with noticeably improved acceleration. (White Buffalo 108.60 inc. shipping)
I set my suspension sag at 33mm front & rear and shimmed the rear shock 3mm. Huge improvement in ride and handling. I may add more shim but the roads around here don't have many tight turns. Cost me about 3 Bucks!
A while back I changed the front sprocket to a 16 and installed a Speedohealer to correct the speedo. Much improved.

I wouldn't have known to do any of this without the info in this forum.

Thanks :lol:
