Well, just ordered the KX450F stage 2 cam and the KFX head is coming off tomorrow to get ported and polished. Should have the ported and polished head back on by monday along with the Hotcams stage 2 intake cam and KX450F exhaust cam then taking it to the local dyno to check the A/F and adjust. I'll post up the dyno sheet sometime mid-next week to see what kind of gains I get. So far my mods are Fuel ATV spec full Dasa exhaust and Fuel ATV intake. Any guestimates on what kind of gains i'll be seeing? Anyone know what the other brand of 450 bikes are putting down with head and cam setups?
