I have two GX390s that I got for $140. One has a cracked block and one was missing coil. So I’m doing a full build for my go kart. I pulled both heads off and noticed on the older one (cracked block) the intake valve was 5mm larger then the other. And the intake was way bigger. Looks like...

I have a highly modified predator 212 non-hemi. It is on my PRC go kart. Whenever I drive it, if I accelerate the chain will break the master link off. I have checked on a stand and there is no resistance with the chain when rolling, so its not a bent sprocket. I am now about to just attach the...
