2007 Bellagio (CARC) with 30,000k. I have a cyclical vibration felt primarily through the left foot peg, very similar to a tight spot in a drive chain.
Uni's/tail shaft has been inspected, and another unit tested. Engine & exhaust mounts re-torqued. All oils changed.
Symptom is most noticeable between 50 & 70kph in 3rde gear, needs low engine speed and more load.
Higher revs or speed it cannot be detected, dis-engage the clutch and coast - it all disappears.
Hold 3rd gear at 50kph going uphill, slowly increase speed and the tempo/frequency slowly increases.
Change to 4th gear & tempo/frequency drops. All disappears by 80kph.
I surmise an input shaft bearing close to 3rd gear, at slow shaft speed the loads are greater.
Any ideas? ...................................................................................Somebody, tell me I'm dreamin'.
