Hey guys I have a 125cc gmx rider x 4 speed manual i am just wondering if I can upgrade the engine so put a 150 in it ??
Without having to do too much tinkering around like welding or cutting pieces off the frame
Hey peeps, need some help. I have a 125 that can't be kicked over or bump started, due to loss of compression I have checked the piston and rings and they seem okay still nothing I'm not sure what from here .
