hey everyone, im new to the quadracer world but had lots of other quads and dirtbikes. i bought 2 quads an 87 and a 91 the 87 im leaving alone for now but want to build the motor up in the 91, it has all new bearings and bushing in it now and when i bought it the guy put a new pistion and rings, a cool head and dyno port pipe and silincer. im thinking about 40 over, a torque plate, power reeds, and carb up grades not sure yet what to do to the carb, i will need to switch the silincer becuase were i ride i need a spark arrester, any thoughts on the upgrades or ideas i should do instead, im not looking to race but have more power and a faster quad. thanks
