I recently had the privilege of buying back my first Harley- a '99 Police Road King. I sold it in '06 and have rotated through two more Harleys since then, my current ride being a 2010 Street Glide. When I bought back my '99, it seems that the vibrations and buzzing are uncharacteristically high for the bike and were bugging the heck out of me- so much so that I figured something must be outta whack. The buzzing and vibrations are apparent at various rpms from 1500-3000 and can not only be felt in the floorboards and grips but visible on the crash bars and spot lamps. Granted, I haven't ridden it in 10 years and my the 2010 is worlds smoother than the '99. However, I also have a friend's '97 Police Road King (evo) that I ride regularly and the vibes/buzzing aren't present in that bike either.

After doing some searching on this forum and the internet, I decided to try the front/rear engine mount kit from Glide Pro. I called and spoke w/Jake several times, both prior to the purchase and for a tip or two during the installation. He was super down to earth and helpful. The kit seemed pricey at about $400 but I'm a little OCD so I elected to buy it.

Installation was pretty simple. I spent about 2.5 hours doing the rear mounts with my bike on a lift and I just followed the directions. The directions were fair-to-good and there is also an online video to watch... I skimmed the video and, in conjunction with the instructions, the installation was a breeze. I have a V&H 2-into-1 ProPipe so even though loosening the exhaust system was enough to get it out of the way to remove the rear engine mount shaft, I took it off to put in fresh exhaust gaskets and guarantee I wouldn't have an exhaust leak issue upon tightening everything up. The 2.5 hours included the time spent on the exhaust system/gaskets. I probably spent another 1.5 hours replacing the front mount. Anyone could probably do the installations quicker than I did but I wasn't in a hurry and did some extra cleaning while everything was apart.

The quality of the parts was excellent! In addition, comparing the front Glide Pro mount with a factory mount or a cheap Drag Specialties replacement mount is like comparing a gold fish to a whale... The Glide Pro mount is much beefier and looks like it means business- I can't imagine it NOT working.

I have everything back together now and am looking forward to riding it in the next few days... when I do I'll post the results.

Until then...

 

I had that in my 07. Hint if you ride the bike and feel vibes in the floorboards, they say it may take a couple hundred miles for them to break in. I had the vibes after the breaking, called Jake and the solution is to loosen front MM bolt rev bike 2-3 timEs up to 3k rpms. Shut off torque bolt to his spec and it will be gone.

 

Yeah, I ran the engine for about a minute, reving it up (but only to about 1500-1800 rpm) a few times before tightening down the front three motor mount bolts. Jake actually told me to ride it around the block before tightening them down but somehow I just couldn't see myself doing that. Maybe I'm being overly weird...

I'm looking forward to riding it and breaking in the mounts!

 

Look forward to feed back. Replaced mine with stock(made in China) front.

 

In 80,000 miles I have never been able to change an oil filter without getting oil all over the front engine mount. Even though I tried to clean it thoroughly each time my factory mount began to rot in about 3 years. Glide Pro said the mount was made of urethane and wouldn't be damaged by engine oil, so I bought one. 5 years and 50,000 miles farther down the road, it works beautifully, just like the day I installed it. I never noticed any new vibration, it has been great.

 

Actually petroleum based products are not compatible with urathene bushings. The kid has them in his suspension and they say no on petroleum based products. Everywhere I searched said the same. Clean it off right away youll be good. From now on when changing oil get some foil and put it under the filter and form a drain to a pan. Punching a hole minimizes oil spilling.

 

Thanks, I do the holes, the foil, the Harley catch pan and stuff the area with towels. Only thing I haven't tried yet is to lay it down on the crash bars to remove the oil filter. Even using the recommended technique for picking it up it is right at my threshold for not being able to do. Guess I'll just keep cleaning up afterwards to the best of my ability.

 

I rode the bike today approximately 15 miles... What a difference!!!! The vibrations have significantly smoothed out to where they should be (or at least my recollection of them, anyway), especially at the floorboards. What I wasn't expecting, however, is the way that the bike's power comes on. It seemed to fall on its face above 3000rpm and just make more noise and excess vibrations... now it continues to pull as I go through the gears and remains much smoother. Glide-Pro says that there is typically a break-in period but right out of the box the front and rear mounts made an improvement. The vibes in the handlebars are much less and are more than tolerable... I don't know how much of the remaining vines are due to the new poly riser bushings I installed, though... the old rubber ones were shot and you could rock the bars back and forth an inch or two before putting in the new bushings.

As a side note... when I removed the old rear mounts, the circular rubber mounts were oblong as though the weight of the drivetrain caused them to sag over the last 17 years/24,000 miles. The new mounts are, of course, circular. And new. Maybe part of the difference I felt is because of the new support shaft too.
