Thank you for the advise. I will look into the mod2 cam. Yep, I am milling the head 0.050.

I need the engine to be have a high torque at low RPM and try to shift the maximum HP at lower speed as well. This was my thought to use this CL1 cam. Do you think I can get up to at least 12-13HP? GX-200 service manual said to replace spark plug and air filter every 200h and clean combustion...

Hi Ole, thank you for the reply. Here is the kit that I am thinking of buying from NRRacing. http://www.nrracing.com/product-p/stage3hopup.htm with Mud motor camshaft http://www.nrracing.com/product-p/dyno-cl1-108.htm I expect to run the engine from 3000-5000 RPM.

I am planning to hop-up my gx200 with stage 3 kit. anyone has experience how long this engine will last before service or rebuild after hop up? this is for gokart use. Cheers!
