You could use an electric linear actuator in place of the stock manual trim control. The manual one has left hand threads on one end and right hand threads on the other end. Turning the middle of it shortens or lengthens it. It would be kind of hazardous to reach down and turn it with your right hand as you ride to manually adjust the lean out using the stock trim control. I would never attempt that myself and would pull over to adjust it, which would be a hassle. Replacing it with a 12vdc electric linear actuator would allow push button control of lean angle as you ride. Two relays, one to make it longer and the second to make it shorter and two buttons along with two fuses is all that's needed to make a control box for it.
I made new bushings for mine. I found a set at John Deere, and used a belt sander to grind it down to size.How well does that original trim system work? The DMC kit locks that stuff down HARD. When I installed my standard trim grip, it seemed to have a lot of play in it because of the plastic/rubber bushings at the mounting ends.
