thought I had it on polaris but was on utility some body tell me how to switch it without retyping the whole thing . anyway read it on utility or here. I was wondeing if anybody has any new imfo on the specific rpms at which the timing limiters start coming in on the sp 500std +ho/and sp700, and/or does anyone know of a fix or way around them ? Have modified sp500/700 and need some help. thanks. also is anybody racing in any of the utility classes on the gncc circuit this season??Im going to try to make 2 maybe 3..

 

I race in the Utility Unlimited class at the GNCC's. Be careful with raising the rev limiter RPM's. They are there to limit the rev's for a reason. I watched a 400EX with obviously no rev limiter blow the engine, literally, apart at the Taylortown, PA GNCC. It sounded like a bomb went off and sprayed so much blue smoke that you couldn't see! I haven't touched anything to do with the rev limiter on mine!

 

what do you ride? were you at loretta lynns last year? Which events do you plan to make this yr.? I ran LL last yr on sp500 mod util. took 2nd in holeshot hit a tree at three mile mark nearly took right front wheel off . still had a blast though going again this yr. will also try to make several others.

 

I'll be doing both Pennsylvania races and the Wisp race in Maryland.
