Re: Arctic Cat 90 Hop-Up Parts Help.
its amazing how little stuff there is for the ac 90. this may help a little. ac, polaris are the same machine,they are made by adly. another one is the drr(they have a website). drr has race parts for theres. sprocets are specel order from any of the costom sproket companys. ac is the most restricted of them all. it comes with a restictor in the exaust, a washer in the carb to not let it open all the way. a spacer in the primary clutch to not let it close all the way.the cdi has a rev limiter. and a 52 tooth rear sproket. if you are looking for race parts try hentrich racing or one of the other companys out there most of the suspention parts will work on your ac.
