so im tired of my crap china girl. ive got a huge list of problems this junk has had. i want something that wont break down after an hour of use. from looking at the gp50 my throttle will work with it, is it the rt carb or something different? what will i need to set up the clutch? i doubt my current one from my kit would work. also what are some mounting techniques? can someone suggest and a 7 speed bike with steel frame, suspension, and possibly disc brakes? also where can i find some good tires.
