I have searched this forum top to bottom trying to figure out how to fix my problem. I thought fixing whatever was causing my foot pegs to vibrate (loose motor mount) would fix this problem as well. I have the tusk d-flex handguards with the bar ends that have a little rubber sleeve around them to dampen any vibration from the metal on metal contact. I just realized today that the vibration is localized to the end of the bars. So, if you are holding on to the grips there is no vibration under the thumb and pointer but there is a very serious vibration under the ring and pinky fingers. I have tried tightening the bar ends to the max which helped a little but it still causes my hands to tingle after 30-45min of riding. Any ideas?
