This has been going on for a while now..when ever i ride up the near red line on my 600rr (redline 15K) the bike would vibrate a lot !!!! To a point where my pegs numbs my feet, and bars numbs my hands. Usually not an issue because i rarely ride that hard.
Now, there several things i considered as the reason why this is happening.
1. I have a shogun- frame slinder. It shares mounting bolt with my engine mount. Maybe it wasn't torque right ?!
2. Maybe higher grad fuel ? (i run 91 shell) Or needs a tune up ?
3. That is just the way it is..deal with it.
