Model: Honda Sh 300
Part: Engine

In this tutorial (see video), you will see how to perform proper maintenance on the engine and gears of a Honda SH 300 scooter. To restore the scooter to its original performance, carry out an internal cleaning of the engine to restore compression. Also, clean the gears to eliminate noise. Clean the throttle body and the injection system with the appropriate additives. For this single-cylinder engine, we recommend the PRO 10w-40 Racing Bike Nanotech from Fluip Motor Oil. In the gearbox, we used the PRO 75W-90. At the end of the service, you will notice a significant difference in the quietness and performance of this SH.
