It might help posting this in the Can Am forum.
Also do a search for OMR carb mods.
You really need to get you jetting dialed in.
A good place to start would be to raise your needle 1 clip and up your main by 1 or 2 sizes.
Also a Dyno jet kit along with the carb mods would help it did great for my 01.
Good luck
