I have a set of power incorporated pipes that i was goin to put on my 97 mxz 583, anyone ever used these pipes? wondering what i should try for jetting or clutching? any help would be apreciated

Let me guess. You got the pipes at the Wausau grass drags.

No I didn't buy them in wausa, I bought them new a few years ago,

Are you running the stock airbox? How about studs? Here's what you could try if running a stock airbox. Go up two on the mains. I think the power pipes spin about 8000 rpm. 228 ramps. Stock solid pins. 160/290 spring. Adjuster # 4. If studded, try a 200/290 spring. Try your stock 160/290 spring first. If you remember FAST Inc. out of Minnesota, they in the past worked with Ski-Doo exclusively. Almost all of their trail set ups ran 228 ramps. Just some ideas. Good luck. If you live near central Wi. let me know. I could meet you somewhere with my radar gun and we could try some different set ups.

thanks for the help, i live about an hour south west of LaCrosse
