Lift With Gx160


New member
I am not racing my kart. I'm doing this just for fun.
What is the maximum amount of valve lift that can be achieved with a stock gx160 head. I think I have the 18cc head and I am not going to be milling it. I want to do a performance cam and I want to know how much lift I can possible achieve without the valves interfering with the piston. Also, would I need to upgrade my lifters and push rods and if so how would I know what length. Also, what do the numbers mean when referring to ss valves. do they mean length or width of the valve.
