If you loosen the bolts on front engine mount and it pulls away from the frame this is not good .

i fixed the vibration by 90% by putting a 2mm thick piece of flat steal between rubber mount and frame .

heaps better

Cheers .

 

THANKS! I'll be checking mine for sure.

 

There was another thread a while back where a guy put a spacer of some thickness in that same location with good results. It looked like the spacer kept the engine side of the mount front being in contact with the frame. I'm going to try this.

 

just watch out , coz when ya take both bolts out the motor will drop and move the the left , but only a little , so but a jack under it first to take the weight to stop this movement .

You can shim with washers. Loosen the bolts, then jack the engine up until you can turn the bolts by hand with no resistance, measure the gap and shim. Also, remove one bolt at a time.

 

Yep, seems like it's probably more common than most realise. I found mine needed shimmed nearly 1/4" when I put the true track on a couple weeks ago. I don't know if it's the TT or the shims, but mine is even smoother at idle now! I'm not real sure why HD can't fix this from the factory. I guess that might take knowledge and an effort, but what do I know!

Anybody notice handling issues or differences after installing this shim?

 

Yep, really helped mine. '07 Dyna, loosened the bolts and it gapped about as much as yours and others have. My gap was about 3/16". Placed (2) 2.5mm washers between the metal bracket and the rubber of the mount. The washers just about touch each other.

The bike was allready on the lift and this mod took all of about 5 minutes with jacking and retorqing the bolts.

Put the bike down and fired up, vibration at idle is down over 50% and vibration running the engine in neural at 3K is gone entirely. Simply amazing! I kinda like some shake in a Harley but had a little too much prior to the washer/spacer install. This forum is the absolute best.

 

Anybody have the torque specs for the bolts when you re-tighten? I don't have a manual, so I don't want to do this until I know what to retorque the bolts to. Also, should you jack up the engine while you're retorqueing the bolts?
