hOW TO CHECK FRONT MOTOR MOUNT
hOW TO CHECK FRONT MOTOR MOUNT
Like the title says.I was riding along and noticed a vibration after I hammered down on it.Felt almost like a flat spotted tire.But when I stopped the bike didnt idle a smooth as it should.Motor seemed to be moving more than normal.But it could just be me.
The front mount does look to be moving a bit.This is my first rubber mounted Harley.
How can I check it for too much movement.

My '13 Wide Glide did the same directly off the dealer's floor, shudder on decel, odd vibrations, and excessive engine movement at idle. I believe it has to do with the alignment of the engine with the frame of the bike, some mounts are installed with the front engine isolator torqued down under tension causing premature failure of the rubber isolator. The HD fix is here: https://app.box.com/s/42af95077c683c50e461
Didn't seem adequate to me so I purchased a new front engine mount and installed it following the vehicle/engine alignment procedure in the SM and my front mount needed to be shimmed out to keep it where it actually wanted to be, there has been no vibrations or decel shudder since then, butter smooth, almost too smooth; when the dealer saw what I'd done to the front engine mount to properly align it they had a deer in the headlights look, they had no idea the bike actually needed to be aligned
Basically, get under the bike and look at the mount and see if the rubber isolator is contacting the front engine mount bracket, if it's touching the mount the rubber isolator is gone, replace the front isolator and follow the alignment procedure when you install the new engine front isolator. I needed to use longer grade 8 bolts and several stainless washers to put the mount where it wanted to be located, but since then there has been zero decel shudder or odd vibration, the mount is still clear of the front engine bracket and still shows no signs of collapsing, it's no longer under tension and can actually do its job... isn't rubber mounted fun?
