My '06 Ultra has developed a vibration in the floorboards.First problem I found was the front motor mount, replaced it with the -79D mount, what a piece of crap. Installed a Glide Pro mount cured the shaking at idle, but still have the vibration. It's a high frequency thats painfull after a few miles. any ideas would be appreciated. If the flywheels have shifted it's getting traded.

What kind of pipe? Did you check the heat shields??

Mine had the vibration that was cured by the stack on the compensator nut,  I shimmed it and that brought it down.  Had another vibratioon that was caused by the rear mounts, replaced all the mounts at around 50k.

I too installed a Glide-Pro front motor mount and had essentially the same issue you were having up until about 500 miles or so and it just disappeared.
Guess it takes a few miles to break in.
Just my .02

ditto.

How many miles do you usually get out of a glide pro mount?

I think they are pretty new so hard to tell.  I would however venture to say they should wear well.

Have the same problem as you and am waiting for my Glide-pro to arrive......Did talk with Jake (Good bloke) and he suggested to me to only torque it to between 22-25ft/lbs.....Now that's a 05 RK. Just my .02

Good luck

funny he told me to torq it to 35 ft/lbs even tho the instruction said 30 ft/lbs.  maybe he is guessing as he goes along.  One thing is that kind of bugs me on the torq thing is the nut is a pinched nut (lock nut via being crimped) and I think that would have some effect on torq.

Dogbone,

Check the floorboard mounts to the frame and also check the floorboard pads to make sure the large nipples that go thru the metal floorboard aren't split.

Ed, I replaced both floorboards yesterday, The rubber isolate rs were cracked and mushy. The new boards helped, but still have a vibe. I'll try tightening the mounts today. Also going to check the exhaust and heat shields.

Check the shift arm on the trans for tightness  Butch

Just in reading the descriptin, the glide pro front mount sounds pretty much to be the same as the V-Thunder "Velva-Ride" by comp cams. Anythig different about it.

I have not seen V Thunder's mount, but the Glide Pro is a soft urethane. It's shaped alot like the first OEM mount.

Checked my exhaust and heat shields. Several hose clamps were loose and the worm drive of one clamp was jammed hard between the right rear pipe and a allen head Capscrew on the Trans cover. I'll see tomarrow if anything changes. Thanks for all the replies.

My exhaust pipe clamp at the transmission bracket broke and caused a lot of vibration.

something else to check

Same happened to me.  The exhaust mount to the trans. came loose and caused a bad vibration.

Had a cracked primary tensioner shoe, vibrated like hell.  But the high frequency sucker was at the compensator nut for me.  The comp nut needs the shim, it was like a painful buzz vibration at the handle grip and foorboards.  Maybe Sir Garfield has the tech bulletin, had it on the hard drive that crashed.
