Hi new to the forum Just bought a used 2011 650 The bike has 1600 miles looks like it came off the showroom floor. Question I have when riding the bike I go about 10 -15 miles and my right arm is numb the throttle grip vibrates pretty bad the rest of the bike seems smooth. Now my old bike for the last 10 years was a converted to street XR 650 R I could ride it 100 miles with out stopping very little vibration so I don't think its in my head. I was wondering if it could be the fact the bike has so low miles, I did put in half a can of sea foam in the gas tank, or I was thinking could need the fuel injectors synced I had a problem with my cbr 929 before and that was the fix. Any advice would be helpful. Ive only rode about 50 miles so far.
