Vibration when riding.

I have an 01 Raptor 660 I have noticed that while riding my hands are getting numb and falling asleep. Today I payed more attention to it and am thinking that Its coming from a vibration in the handle bars. what could be causing this is this normal.
I have a little slop in the handle bars from side to side before the front tires turn. I have tightend up the nut that holds it all together but doesn't seem to change today. Any thing I could look for.

The vibration comes from the engine, not from the suspension.  You may have a loose or broken motor mount or some other related issue.
