Title: Vibration Through The Tank ?
Post by: Ed_in_Az on April 07, 2004, 07:51:25 AM
Between 5 and 6 grand, in fourth particularly, but other gears to a degree, accelerating or decelerating, the gas tank buzzes, mirrors too. The pegs and seat don't vibrate. It's puzzling. Anyone else encountered this?

Title: My 91 does it...
Post by: The Buddha on April 07, 2004, 08:17:48 AM
My 91 does it... my 89 does not. Anyway the reason I believe is the rubber bushings on the sides on the tank are either worn out or missing. I found one on my driveway last weekend  :x  ... and its now making a nice accoustic echo... through the tank and inside it and on the skin... and I hear 8 octaves and its beautiful  :? ... just like a duc monster.
Cool.

Thanks, scratch. I actually checked the mounting bolts and all seemed OK. I'm glad it's no big deal. I might look for anything else that might be loose, but this little beast sure runs good. :)  Accelerating over a small hill in town the other day it tried to wheelie.  8)

Maybe I just need to tune my tank.  :roll:

Yeap I get this too.  Actually the rearsets seem to vibrate alot around 6000-7000RPM.  Sometimes I'm nervous it will make my feet numb while riding if I don't move them.  Not a good situation  :o

Mine too, but only when my gas gets to aroung a half a tank, anyother time it doesn't.

That's it!  If you drill a row of small holes in the tank, you really free-up the fuel flow , the stock tank is too constricted ;)

I spent a summer trying to figure out a vibrating noise I had....fairly disconcerning.....until I layed up on the tank to listen closer...and what do you know it stopped!
