ok here is the deal i have an 08 kfx450 i just went threw and put in a new wiseco 12.4:1 pistion and when i put it back together it has no top end it just seems like it bogs after half throttle. i have a race DG pipe and a pc3 and a K&N filter. im running a Power commander preset map from there web site. i didnt know if i needed to change the map or what. i have cheaked the valves both the exhaust valves were gaped about .011" so im ordering new shims to bring it down to .007" but it was not that bad before i rebuilt it so i figured that it had to be the fuel map plz i need some insight on what you guys think it is and if anyone might have a map for about the same setup just something to get me started.
