All sorted, I had fitted a Scorpion exhaust and perceived that it had slightly increased vibration levels, I have to admit that it was probably more in my imagination than a reality but did fit "Grip Puppies" which for me have improved the feel of the bike. I also rode a friends V-Strom and it was exactly the same as mine so it looks as if I was coming up with a problem that did not actually exist. Just to note I got a shot on the new Kawasaki Versys 650 now that really is vibration and of the most horrible kind.
