LOOKING FOR PERFORMANCE MODS FOR AN 02 XC800 MOTOR IN MY 99 XC700 CHASSIS. RIGHT NOW ITS ALL STOCK LET ME KNOW WHAT WORKS BEST. THANKS LUC

I have a buddy with the same sled and his is piped, clutched, air box is not stock and some gearing done and all i can say is that sled hauls ass. He raced a apex with the turbo and smoked him across a small pond. Both were picked and balls to the wall. GO POLARIS!!

A set of HTG pipes work great on those motors, also clutching and gearing are a must

in all honesty for that sled i would run either an aaen single pipe for the huge weight loss or the twins for the rpms, gear it down for about a 90-95mph 1-1 ratio with whatever pipe you have, then some good clutching. if you are more of lake racing i like the 48-38 or even a straight 36 helix with as much weight as you can pull.

ONE OF MY BUDDIES TOLD ME TO PUT AN ALMOND w/BLUE SPRING IN THE PRIMARY & 10-68G WEIGHTS AND IN THE SECONDARY TO KEEP THE SPRING BUT PUT A 52-34 CUZ I'M NOT A SMALL GUY I'M ABOUT 270 LBS.

you will want a 36-38 finish angle on the helix, i did a 600, stock springs, put in a straight 36 helix and added 2 grams to the primary, goes like a raped ape. he ran down many 800 xp skidoos in the 1/4 mile drags.
