My wife drives a 99 Z 440. Its a great sled and she loves it but the throttle is too hard for her. She complains after a VERY short time that her thumb hurts. I know the twin carb setup is a harder to pull than a single carb but i'm not going to pull a carb off. We have taken rubber bands and put them on the throttle to make it easier but that kinda scares me. Any suggestions?
