Bad Bike Vibration
Looking for some help with vibration seems to be getting worse. I feel it mostly in my feet left side more than right. I took the bike to the dealer for this problem only because I have an extended warranty. They replaced the compensator, clutch hub, transmission bearing, selector shaft seal and oil cooler also had rear tire re-balanced and new belt. At 70 mph it’s bad and gets worse the faster I go, feel it in both feet. If I pull the clutch in at 70 and let the engine come down to idle vibration goes away or if I pull the clutch in at 70 and hold the rpm at the same rpm no vibration. It seems to only happen when engine is under a load, thinking flywheels out balance bad bearing some place I don’t know. Plus it keeps blowing out the radio that’s how bad it is. PS engine is all stock pipes, a/c and TTS Thanks

Doubtful the flywheels are out of balance, more likely the crank has scissored.
A crankshaft run-out check would have helped to determine that, they should have done it when they replaced the compensator, I'd ask about that.
If the run-out is good I'd start thinking about checking for excessive play in the wrist pin bushings.

had mine doing the same thing a few weeks ago. also had a different sound to everything....a little more rattle than usual......motor mount was loose on mine. bolts on the Bracket from the engine to the rubber mount had come loose and one had snapped. side to side stablizer bolt had backed out also.Rubber mount was cracked so went ahead and replaced that too. back to normal now....a little extra vibes than before but that's because of the upgrade HD rubber mount...stiffer. that being said, it looks like dealer would have checked that when he replaced the other stuff....but who knows....have to remove the oil cooler if so supplied and Voltage regulator to see em good....

After I made this post I went to the dealer to ask about crank moving or scissored as you call it and they said the same thing but to check it on the cam side. He also said that ESP will not pay for that and if they do I would have to pay for it if it's within spec (3-4 hrs). He told me to check it and let him know what I find or just wait for it let go but, by that time the radio will junk again, the fairing supports will have to be replace again, and yesterday I noticed my passing lamp bracket is broken do to this vibration. He told me just take it apart check the runout and if its out he will come pick up the bike all apart and fix it. I’m really **** when it comes to someone working on my bike my sh—needs to be right or I’m upset and I won’t rest till it right.
