I had the same problem with my right hand tingling and going numb rather quickly into my rides for the last 20 or so years. It was frustrating as hell. Cruise control helped but you can't use it in town or back roads. I decided to put grip puppies on to cut down on the vibration I had. The vibration was barely noticeable but I thought I would see if it would help further. It did and it also kept my right hand from going numb/tingling and tired. A $15.00 fix. Give them a try. They may not help you like they helped me but before I couldn't go 10 miles without my right hand going numb. It really worked.
