Anyone ever tried reducing the amount of force required to twist the throttle open? My throttle hand has been going numb, and I think part of it is the force needed to grip it and keep it twisted back all the time. My left hand never has a problem, which leads me to believe it's throttle related. I've tried a throttle lock, but I find it a little cumbersome to use and I only wind up using it after things start to go numb. If I could lighten up my grip without the throttle wanting to close all the time, it'd help out a lot. Any ideas?
