..wow..
...vibration of that magnitude could be caused by a screwed up tire..
..one would think that there would have to be a lot of ..mass out of balance.. to cause that much vibration...
..at what speed does it begin...
..is it incremental...get worse with higher speeds??
..is it coming from the front or the rear...should be able to get a "FEEL" from it's origin...
..or, it coulda just been a fastener that worked loose...
..my left-hand, center stand pivot shoulder bolt, backed itself out...
..the ONLY fastener that has ever worked loose on my scoot tho...
