go with a 1mm larger intake and leave the exh at 23. get the kitaco intake off of dr atv-pricey but noticable gains. run a 28mm carb and maybe toy with cams although the tb300 is pretty good

Superhead....



Seriously, what you need is a flowing system. Faster in, and faster out. Big valves, matched with clean intake and exhaust ports, with more fuel and air... means more power (in the simplest of terms).





Who knows how much your current clutch and transmission can handle though.
