  • Great upgrade for 125cc size bike
Color: Silver+140CC 4-Stroke
Great upgrade for your blown 125cc. Better guality...smoother run ing. Wire diagram a little challenging...takes 2 gas tanks of rum time to smooth out gear vox. Runs very good and stronger than a 125cc. 1 gear very low and taller gears 2 through 4th. Good value . Throw away the carburetor a d upgrade to Japanese carburetor and this engine will last you 10 years. ... show more

  • Runs as it should.
Color: Silver+125CC 4 Stroke
Good engine for my golf cart conversion, vendor has no idea how to address issue with start solenoid due to language issues. Could not reconcile after many contacts. Used an old Ford part to keep me running.

  • Good for someone with carb skills
Color: Silver+125CC Single Cylinder
Motor is solid, gear box is sticky at first will slip into a neutral in between gears no grinding though. carb is sucks haven’t found a carb to make it run right yet if you are decent with carbs I believe the motor will hold up good. Would recommend if you have carb skills
