Back in my days on 2 wheels, I had a Honda inline-4 that I could stand a nickle on edge sitting on the fuel tank - and rev the engine full throttle, and the nickle would not move. If I tried that with my later model Harley-Davidson V-twin, I would have to super glue the nickle flat to the tank - and the nickle would still fall off at IDLE!
Truth be told, the shift lever fell off on the highway two weeks after I bought it brand new! THAT is how badly the thing vibrated.
Even with a 3-phase motor some grinders have to resort to using air bearings to keep down the level of vibrations do they not?
Yeah, I'm blathering...
Harley's are suppose to vibrate. That's part of their "charm". And also be LOUD!!!!!!!
