Without sounding like too much of a wimp, I'm still new to the ATV world. I went out and rode for about 30 miles the other day and my right hand is killing me. I've got a Yamaha Grizz 450. How do you guys that ride all day long manage to do it? I've got the thumb extention but opted not to use it yesterday-guess I'll install it but I'm a little unsure how much of a help it will be.
