Im building a race GY6-150 motor for my daughters Gokart [see other post],So far I've got the following parts,NCY63mm BBK,6mm stroker crank,A9 cam with adjustable cam gear,NCY variator kit and Im using the 30mm pumper round slide carb off the current motor.
im having trouble deciding if i should use a 4 valve head or go for big 2 valve?,it seems there is little info on the 4 valve heads and Im worried maybe thats for a good reason ??.Also havent found anyone selling cams for the 4 valve head?
Also wondered if stock oil pump and starter clutch are up to the job or ??
Appreciate any help[from those that know],thanks
