just put a new front end on my 89 gixxer and when deccelerating from 4.5-3.5 k rpm in 4th 5th or 6th gear there is an nasty tank slapper like vibration through the front end. It only happens at that engine speed in those gears. Could it be my front tire is not ballanced. Also the forks sit a little lower in the triples than my old forks which means less wieght on the front end, would this affect anything. Any help would be appricated.
