I have an '09 VN900 custom SE, and I decided that it would look and feel much better if I installed aftermarket grips. I wanted to start with the throttle because I am a little scared to cut off the other grip. Turns out that it hits the bar-end and sticks. I have read on another thred that it was prob the bar-end. Well, thats all well and good, but how do I fix it?
