I know I can't be the only person that has this problem, so I'm hoping someone else has found a solution. After only about 10 minutes riding on my honda foreman my thumb starts to cramp. After 15 or 20 minutes it's either numb or in pain. In cold weather my thumb is frozen. I did put on a thumb throttle extension and that helped just a little. I've seen some twist grip throttles but am not sure how well they work or which one to get, or how complicated it is to install them. Please give me some direction and advise.
Thank you,
