triumph speed triple 509

I just picked the 1998 T509 up second hand and am experiencing the vibration problem at about the same RPMs under load. I've seen reports of this problem elsewhere and am hoping someone has solved this problem. My guess is the clutch.

Anyone know how to fix this?

Hi guys:

Get the injection sorted out before playing with the clutch. I have a '97 that had barely seen any riding before I bought it, was barely rideable in general while having the specific "feature" you mention here. Went to the dealer who informed me mapping was way off. Now it runs fine.

Greg.

linsler,
Thanks! I will do this first.
