Default Vibration @ 3000 RPMs

Has anyone had this problem? I notice whenever I run up to around 3k rpm I feel this vibration coming from the engine or rear drive that seems like it saps the power and I don't know where to start to find the problem. I have a power commander, v&h duals, se air cleaner, 8400 miles, syn3 and it is dyno'd (about 4k miles ago). Any help would be appreciated.

I too have a vibration at 3000 rpm....mostly thru the floorboards though...I've checked engine mounts, belt adjustment, tire pressure....haven't been able to put a finger on the problem though, hope someone can give some insight to this potential problem...

Maybe make sure that the muffler clamps have not shifted and are letting the mufflers vibe against the support brackets. Had that happen on my RG more than once.[sm=escape.gif]

Scissored crank assembly?
