I just bought a new Motorcycle Wheel Chock from Harbor Freight for my bike lift table. There are three mounting holes vertically on the Pivoting Bracket Mount, the part in the back. The directions say to adjust it for the motorcycle to be loaded but provide no guidance information.
So, my question: Does anyone have one of these and how did you set it up?
I have one bike with a 18" tire (K1100LT), and one with a 19" tire (R100).
Your assistance would be appreciated.
