I have mentioned this before in a couple of posts I have made in the past but thought I would just see if anyone else has this specific vibration. It also coincided with me wiring loom shorting out some time ago, I was one of the first people to have this happen and thanks to the mechanic at Suzuki, we got it sorted and then I posted about it on this forum and the UK one. Anyway this vibration happens only at 3500 and shakes the bejesus out of the left hand plastic tank panel. It happens as you go up the rev range and back down again but only in a very narrow band of 100rpm or so. When you put your hand on it as it goes thru this rev range you would swear there was no way to prevent this from happening. However the rhs panel, nothing, completely unfazed. Anyone else experienced this? I am going to pull my bike down soon to fit new steering head bearings and will remove and refit these panels but it seems more than just a loose fitting somewhere? I am going to remove my Givi crash bars first and do a test run to see if it is that.
