Not been here for a while but Super 10 now gone and I have bought a 660 which I plan to use on and off road.
After picking it up I rode 70 odd miles home and 1st thing I noticed was the horrendous vibes / noise and lack of pull, now I had a new one of these back in 09 and don't remember them being this bad, in fact mine was pretty smooth for a single and so was a 07 660r I had, both also pulled really well. This one has MTC cans which is the only mod as far as I can see, std air filter, new'ish C&S so the dampened OEM front sprocket will have gone. changed the oil and filters + new plug as a matter of course.
Also mate has one identical except he has Leo Vinci cans, his is so much smoother and pulls really well and his ain't got any rubbers on the pegs with Renthal bars and no bar weights !!
Any ideas on what's causing the vibes gents
