Default FLHRCI vibration problem...Advice Appreciated

I am having vibration problems all of a sudden too on my 08 FLHRCI.

Vibration is at any speed.

I also feel it when stopped at stoplights, and under my floorboards especially on the highway.

I thought about a badly balanced new front wheel, but wouldn't I feel something unusual in turns? And that wouldn't be a problem at a stoplight.

Bike handles normally. The vibration frequency gives me an upset stomach.

I have also noticed some of the rubber mounts for the exhaust pipes deforming and shrinking. I'm also assuming this is possibly because they are drying out and need to be replaced. could it be the same with the rubber motor mounts? Are the two made out of the same rubber?

I personally favor the idea of a rubberized motor mount issue, but I would like as much input on this as possible before I make a move.

If it is motor mounts, is replacing them an easy dyi?

Bike has 15,000 mi. and is 2.5 years from new.

Thanks to anybody.

a vibration at a complete stop that increases with engine RPM could be a crank that is out of true. do you have any leaks? check your engine oil magnetic drain plug for metal chips and check the drained oil for aluminum chips.

Most likely cause is the front engine rubber mount has collapsed, in front of the crankcase. This thread gives some idea of what to look for.

I looked into those things and both are ok.

I was also thinking could the engine be out of tune?


thanks
