Engine vibration?i
My 03 Electra with a 95" has developed a pretty wicked vibration that is felt through the bike but it's real bad in the floorboards. It happens at any speed (MPH) as long as the engine is above 2k RPM. If I pull in the clutch while riding it goes away and if I increase RPM with the clutch still pulled in the vibration comes and gets worse/faster as the RPM increases. Seems like it has to be engine/trans/primary related. I have the BDL compensator in it, and it was fine while it was in there. I just replaced the front mount with the Velva Ride and it didn't change.
What's the best/easiest way to narrow it down? Has anyone seen this before? I'm thinking possibly crank, but how can I determine that without pulling it all apart? Will a runout test tell me? Do I do one side or both? Any suggestions would be great. Thanks.

I replaced the front one already and there was no change. Took the rears out and inspected them and visually they looked ok, but I'm not sure what I would've seen anyway.

Took the primary side apart tonight, found the BDL Compensator was loose, meaning the threaded part of it and outer nylon washer were loose. Removed the nut, tightened the compensator back up, and retorqued the nut. Gonna ride it in the morning and see if it changes. If not, I think it's going to MBBW for the weekend and I'll worry about it when I get back.

I put some miles on it over the weekend, it still has a floorboard vibration. I'm gonna get the cam plate off and measure the runout. What's the spec?

Harley says .012" before they'll warranty if applicable, which is ludicrous.
Be aware, that not only can the pinion side slip, but the sprocket side can as well, independent of one another.
Worst we've ever witnessed was .042" on the pinion, and it also had .016" on the sprocket shaft.

After reading that tech tip, it states that vibration is usually on the sprocket side and that excessive runout on the cam side causes oil pressure issues. I guess I should do both to be safe.
