I attempted to build a stock appearing predator and it looses power when i'm on the track around 5300 rpm. It seems like it is loosing fuel so I am not sure if it needs a fuel pump or is jetted improperly. This is what I have done to the motor and it still has the top mount fuel tank.
nr racing marine cam 280 lift
longer arc rod .020
shaved & ported head .050
28lb springs
arc flywheel 32 timing
gutted exhaust
stock air box with more flow
.650 nr racing carb
any help would be greatly appreciated and do you think a fuel pump would help
