A close up of the throttle. These are the grips I bought from Karl [MENTION=48751]Not so mini bike[/MENTION] for $27 shipped. They are made for 1" bars. (I assume Harley) What I didn't figure was that if I installed them on painted bars which allowed me to see through the grips to the paint below, the first time I moved the throttle, the paint would scratch.
First I tried the Arlen Ness "Throttle Bearing" which is a piece of rubber inserted into the bar end, to which an allen bolt is threaded, to which a bearing at the end of the throttle rides. It didn't prevent the rubbing I was concerned with, so I cut the bars off just outside of where the throttle clamp is retained. To that I slugged on a 7/8" bar I cut from a Cat set of bars. I then modified the Ness rubber insert to fit the end. Results accomplished. This is by far the smoothest throttle of any machine I have ever felt, and that includes every motorcycle I've ridden, or owned since 1969. I am more than happy with the way it turned out. Note the 1/16" gap. The bearing on the end of course is hidden by the grip.
The dummy side worked out fine, except that I did have to notch the grip to accommodate the brake lever.
The throttle feels so good when I grab it, I just can't stop doing it. Grandma said this was wrong, but so far, no hairy palms.
