Review on Optimized Proform 66514 Harmonic Balancer by Steve Douglas

Revainrating 5 out of 5

Works perfectly. in the "Engines and engine parts " section

Works great. Make sure you lubricate the threads going into the crank and the threads on the mainshaft. Makes the product easier to use and easier to remove from the handle.

Pros
  • Few competitors
Cons
  • No instructions
