Topic: What to replace on kohler

[Darkviper]

Im thinking about one day building 15hp kohler built it up but idk what to replace but the cam, rod, piston, port, idk how far to race compression. thanks for the help.

Stock cam is junk. Will snap over 6500 rpms. Had 3 of them do this, all in the exact same spot. Call Julian @ Super Cub.

Can you use the springs and roller rockers and do you have to get weights or is there another way?

You'll want to buy new springs for anything. Roller rockers are fine with any cam. Spring pressure is what will kill rockers. If a mild build stock rockers would work for a while going by the looks of them. I will say though mwsc has some sweet lookin rockers. As for cranks and weights, a stock crank can be used but you will have to find somebody to balance it or do it yourself. If you call Julian at mwsc and buy their crank it has bolt on bobweights. Truly a sweet piece.  And they can balance it for you

Can you run stock crank stock rod idk what but i probly need smaller stock piston and mild cam for kohler like kawaskis do besides getting retainers and automotive springs. Do you still have to balance it?

[Burton for Certain]

Stock crank will be fine. Super cub has diamond pistons that are stock bore. No idea on the rod. Sbc valvetrain works. You should always balance a motor.
