How to Repair Harley Motor Mount Vibrationsby Robert Good
If a motor mount on your Harley is vibrating, the motor mount is loose or the securing bolt holding the motor mount in place is stripped. The motor mount(s) will be located toward the front of the Harley's engine, on the bottom of the engine between the frame and the engine. Some Harley motorcycle models with large engines have two motor mounts, However, most Harley models have one motor mount and one transmission mount.
Place the motorcycle jack beneath the engine block and raise the jack head up to the engine block to take the weight of the engine off the motor mount. If the Harley has two motor mounts, determine which mount that is vibrating.
Remove the motor mount securing bolt from the center of the motor mount using the ratchet set. Pull the the securing bolt from the mount.
Inspect the securing bolt. Look for stripping of the bolt, rust, bending or any other damage. If the bolt is damaged, replace it. Any local Harley-Davidson dealership should have the replacement bolt.
Replace the securing bolt to the motor mount and tighten the securing bolt using the ratchet set. Tighten the bolt so that the mount cannot move.
Start the engine and rev the engine a few times to ensure that the mount is tight enough that the mount is no longer vibrating.
