Vibration isolator mounts finished

I made my own isolator mounts and the turned out well.  The problem was that the 60 duro urethane was just too stiff.

I bought the VC isolators (left) and they did an OK job, but still were on the firm side.  I went to McMaster Carr and picked up some softer mounts (right).  The softer mounts did an outstanding job of keeping the vibrations away from the rest of the cart.

The next issue was dealing with engine moving back toward the rear end during acceleration.  Even with the stiffer VC mounts the engine moved back.  And with the softer mounts it was even worse.  I thought about doing the torque strap/cable that Yamaha uses but found a use for the VC isolater mount afterall.

This is what the cradle and engine mount plate look like:

The engine doesn’t move back while keeping the vibrations to the rest of the cart to a minimum.
