Engine Vibration

RE: Engine Vibration
I'm an old R&D tech, having done a lot of shake/vib testing, I appreciate the tech notes. Am presently riding a 12 yr old Evo all ridgid in a my own custom frame. After having to put up with heavy vibs at 60-70mph, haveswitch to 24T main drive sprocket. Can cruise now without hitting that resonant freq up to 80+. Kinda like a cruise conrol.I've owned 1 ea. Knuck, Pan, Shovel and Evo. They were all shakers and rattlers. The Evo makes as much mechanical noise as any Pan.The ol' lady got me to riding with a Full Face helmet on longer rides and it does wonder to cancel allthe high freqs leavingthe nice boom of the open pipes. Envy you your knuck, Have fun!

RE: Engine Vibration
Hi DACONIAM ,A vibration meter is a small instrument that measures vibration in inches per second.It is used regularly in industrial plant maintenance to monitor the condition of bearings on shafts ,gearboxes, etc.The tip is simply pressed to the machine to be tested and it shows a digital reading of the vibes. The one I use is A VIB PEN model CMVP20 made by SKF bearings .Sells for about $600.It was a big asset to me when I visited H-D dealer.They and the MOCO could not argue with the meter mainly because it does not understand english; it comes from Japan.If you have a friend who works in an industrial plant ,he may help you borrow one.
