First thing you'll need to do is ditch the stock intake..at the very least do a search here for theduv, he built his own using a ltr tube...and you'll need a pciii to tune it...can also change the gearing to a 15 up front but i'd probably wait till you change take care of the intake & pciii first...that'll get you decent power.Hey guys and gals. I have my 08 kfx450r with a single stage genisis chip with fmf slip on and uni filter. Lots of cosmetics that made her loose some weight but it still isn't fast enough. Yesterday I raced a YFZ450 and I lost. Not too happy about this. I'm just lookin for some small hints on how to go faster bottom and top end and not spend too much.
