Naraku Racing QMB139 Transmission Kit 788mm for 4-stroke GY6 50cc, 139QMB

Complete transmission kit of Naraku components, all tuned to another. Since Chinese-built scooters are not kitted with top-end components out of the factory, this is the easiest way to overhaul the transmission without expert help. This negates any restrictors. Top speed and drivability on hills is improved, meaning higher top end and better acceleration!

I have tried the other performance kits which are more expensive and they don't even compare with this one. Part for part, this kit is the best and most affordable out there. The clutch itself is worth the money and the belt is the strongest I have ever used.
