How to Adjust a Loose Chain on a 125cc Motorcycle?
1 Answers
Lift the main stand, use an adjustable wrench to loosen the large nut counterclockwise, and use a 12# wrench to loosen the adjusting bolt lock nut, then adjust the adjusting bolt. Adjust until the tightness is appropriate, ensuring both sides have the same scale marks, then tighten the adjusting bolt lock nut, followed by the axle large nut. Apply lubricating oil, preferably using a dedicated chain oil if available.
