was thinking of upgrading carb, putting a lrd exhaust on my blaster, was wondering if a 34mm would be too big for the stock motor, if i would see any real jump from it? by the time i have the exhaust and the carb, it will also have the v force 3 reed valve and cage assembly on it, it has a 1/2" spacer, i just ordered the jet kit and carbon reeds in it right now, anything would help.
