I have a 2002 Rmk 700 151" track with a brand new crete motor from tri-city and twin cpi pipes and v-force 3 reeds, I pulled the main jets and they were 310's and I talked to tri-city polaris and they said with those pipes and reeds my sled should run 380 main jets in it so i bought some. I rode it twice at 8390feet altitude pulled my plugs and they are black and wet, my question is, if i went to 350's, is that too big of a jump? where should i start? thanks guys hope you had a good christmas!

Jets are cheap, I would buy 370's and 360's, and go down by 10 and test until you find the sweet spot. Replacing plugs is LOTS cheaper than replacing pistons...
