Vibration - what vibration?
I had a bit of a tingle in my bars that started last fall. I looked around for it from time to time, but only recently did it get much worse. My left side mirror and grip vibrated quite a bit at certain rpms sometimes. It was hard to figure out the cause since it was very intermittent. Today, I pulled my primary apart. Everything looked fine. My comp nut even felt pretty tight. When I got my rotor off (which I had suspected for a while), I found the problem. Apparently, the comp nut was just shy of tight enough. The teeth on the rotor were worn down significantly. The vibe was the rotor wobbling back and forth on the shaft. I feel lucky it didn't damage anything else. My stator is ok as is the bearing in the case. I just happened to have an extra rotor here in my shop, and now, all is good again. I just wanted to post this in case someone else was chasing a vibration. Check your compensator nut and rotor!!

Off topic and maybe a coincidence, but I changed out my Longshots for some Big Radius and now it seems my bike is vibrating more. I mainly feel it in the floorboards. Maybe just the pulse out of my now shorter exhaust is causing the problem or maybe it's just all in my head. Anyone else experience this?
