I am not sure if I'm posting in the right area but I have a question about preventing hand numbness. I bought a crampbuster and use it all the time. However after about 30min of riding my hand begins to fall asleep I have tried many different positions of my hand on the throttle and still end up with the same result numb until I ride the clutch and can fully release the throttle. I can feel a bunch of vibration in the throttle only. It feels like a dual action sander. I don't know if there is a problem with my bike or it is just me. If anyone has any suggestions I am open to them.
