Well, take it apart and I reckon you'll find the problem. Just about every clunky NSR I've dealt with has been because of this torque arm or worn out engine mount rubbers.

I had an engine pack up.....I looked at it for days.....even gave it a threatening stare, but in the end still had to disassemble it to fix the problem.
