  • Must have.
This is a must have for all motorized bikes. I have used all the nuts to lock down the motor so the nuts don't viberat off. Have use the motor bolts to replace broken ones. Have not had any problems after doing this.

  • Recommended if you have issues with your original studs
This worked perfect for my 80cc China 2stroke engine, my engine mount studs were bent and stripped from previous owner so I ordered this kit and it came with more than I expected.
