C100 Intake & Exhaust Valve Assembly (Performance Upgrade)

⚡ Performance Upgrade · Complete Kit · Increased Torque & Acceleration

For Moped, Cub & ATV · Fits 139FMB, 147FMD, 147FMF, 150FMG engines

📋 Product Overview

This is one of the cheapest ways to get real performance tuning – the C100 Intake & Exhaust Valve Assembly. 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. This valve set can, of course, be used with original (restricted) engines. Its strongest point is that it provides higher torque which translates into better acceleration.

This product is suitable for Mopeds, Cub series, and ATVs, and fits engines including 139FMB, 147FMD, 147FMF, 150FMG, and similar models.
