2007 Arctic Cat 90 speed mods
Hi, I'm new to this board, looks like some really knowledgeable folks frequent here so I'll toss out a question.
I just picked up a new 2007 Cat 90 4 stroke utility atv. It is too slow for trail riding and I need to increase the speed.
There is no exhaust restriction, can't find any wire that doesn't belong on the CDI box (maybe 4 strokes don't have the jumper wire).
I'm going to crack open the CVT case and see if there are shims in the sheave. Anybody know of anything else I can do?
