Alcorp Posted March 20, 2005 Share Posted March 20, 2005 My 87' FZR1000 has a strong vibration at 4500rpm in all gears and neutral, it passes as soon as i pass this rev range. I suspect the problem is not gearbox related, any pointers ?? Link to comment Share on other sites More sharing options...
Moderator YamaHead Posted March 20, 2005 Moderator Share Posted March 20, 2005 My old XJ750 used to do the very same thing @ the same revs I think I narrowed the culprit down to a camchain tensioner issue along with a need for a good carb balancing.

solorider Posted March 24, 2005 Share Posted March 24, 2005 all 4 cylinder bikes will vibrate at a certain revs,if the carbs are balanced it is better to adjust your speed to suit or alter the gearing Link to comment Share on other sites More sharing options...
cterror Posted April 1, 2005 Share Posted April 1, 2005 the old pre-exup engine is a bit more vibrating than the newer one... and still the t-ace owners keep saying that it vibrates. nothing really you can do to it. carb balancing as said before. also a bit of help if you change the handlebar grips to "soft" ones. and add some massive antivibration endbars. no carbon here Link to comment Share on other sites More sharing options...
