Whats better ??? Boring the stock carbs to 35.5 or finding a set of Ski Doo 38mm carbs..?? If using Ski Doo carbs what about the TPS...???
 

38mm carbs are only maybe 2-3hp more at wide open then boring the stock rack, nothing your gonna notice. As far as the TPS goes, it only controls the map ever so slightly during part throttle cruising, has absolutely no effect on power wide open, checked that on a dyno. You can buy a psi block and run a throttle cable with 2 outlets or make your own block. thats what I did, I worked it off the oilpump cable, ran premix anyways in my drag sled. If you wanna save alot of hassle just bore the stock carb rack to 35.5mm and call it good.
