YEAH, Rick!

I'm still waiting to see how that Swaintech piston is doing in that 400 cylinder. Piston sure looked pretty cool though. Got any on stock for a 300? Don't need it right now but I'm sure I will.

 

the first thing to do when ported cylinder is changing the primary spring to match the new engine powerband,if jetting is right then you might
RESET your whole clutch setup (belt deflection measures is very important)and try it out,with all the mods you get you should not even think about EX...

 

the power has been found. replaced broken ramp buttons and bought new epi helix. Now i can out run a 2001 raptor with fmf exhaust and k&n filter with new jets.
