Default Engine vibration ???

Have 2009 Electra Glide Classic 96 CI

I notice, barley/slightly, a vibration, around 2500/3000 rpms...
Just wondering if this is somewhat normal.

I notice it going thru the gears.... so I don't think it's the Primary or gears...

Like I said barely noticeable. So I;m thinking it a feature....

I have 1999 Softail Evo, and the Evo's definitely have a vib. at certain rpm, just a feature of those.
The EVO is much more noticeable than the TC.

So I was wondering if it was the same with the TC.

Check your engine mounts.
I've never noticed a vibration on my Electra Glide other than the shaking at idle.
I hear oil can destroy the lower front mount if you let the oil run on it when changing the filter.

I have no vibration on my 09 ultra classic either while rolling.

To clarify, this isn't noticeable when cruising, only when accelerating and when you get to 25-3000 rpm....range. and as mentioned barely noticeable.

2500-3000 is lugging the motor for other than cruising. You are hammering the bottom end at those RPMs with hard acceleration.

I usually shift before 3000. Peak torque is around 2800. My bike does not "lug" unless I roll on at below 2000. FTR, I have over 100,000 miles on my motor and it still runs strong.

I would go through and check the basics:
  • Condition of tires
    • any cuts
    • even wear
    • pressures
    • road tar on rims
    • wheel bearings
    • missing balance weights
  • Oil levels
  • motor mounts
  • exhaust mount bolts tight
  • handlebar mounts
  • etc.
