I am thinking of buying a aerox standard and tuning it, I want to to put a mallosi 70cc bore kit, Doppler crank (anyone know how much it will cost to fit a crank at a garage), 6g rollers, mallosi multi varitator, mallosi belt, torque spring(not sure what one to get), race clutch springs, 19mm carb and manifold, is there anything else I would need to make it as reliable as possible, thanks
