C100 In./Ex. Valve Assy 90-110cc

One of the cheapest ways to get real performance tuning. Working closely together with various 4-stroke scooter manufacturers, we have managed to increase engine performance and running smoothness. The result does not affect everyday drivability while still offering smooth running and durability. The Valve sets can, of course, be used with original (restricted) engines. Its strongest point is that it provides higher torque which translates into better acceleration.
