Last year the shift shaft had developed a decent amount of slop, neutral was becoming just about impossible to find and my shift arm would rattle at idle.
Recently installed the Head Hoggers Bagger "Shaft Gripper" vibranium shifter bushing. Have been out for a few quick rides since install and everything felt great, really tightened up the shifter and neutral is much easier to find now. Just about zero slop and absolutely no more rattle.
Well, I finally got out for a decent length ride and all off sudden started noticing after about 20 minutes or so into the ride that when downshifting the shift arm wasn't returning back up to its normal position. I'd have to sneak my foot under the shift peg and slightly lift it back up to it's normal position. This was happening when downshifting from 2nd to 1st and also from neutral to 1st. I get home, let the bike cool for about an hour and the shifter movement is totally normal again.
Anyone else with the Head Hoggers bushing experience something like this when the cases heat up? I'm hoping the bushing just needs a couple good heat cycles to wear in properly...
I was looking into this, and they state that it will tighten up a good bit once warmed up, so you want it a little loose while cold...
Yeah, it seems like mine tightened up so much when hot that it's restricting the movement of the shift arm from returning to position.
I installed everything per their YouTube video instructions. I sanded and cleaned the inside of the primary case bore, sanded and cleaned the shaft itself, used grease inside the shaft/bushing contact area.
I went to the Head Hogger web site and then got curious as to what "Vibranium" is. Someone at Head Hogger must have a sense of humor, as the only answer I found was that it was a FICTIONAL material dreamed up by Marvel Comics. That leaves me wondering of what material these bushings are really made. Anyone know, or would care to hazard a guess? If they expand when hot at a significantly greater rate than aluminum, will they eventually crack the shift shaft area of the primary case?
I don't know anything about their bushing, but their puller tool ($15.95) seems like a great option and value over the JIms #5518 Shift Pedal Shaft Bushing Tool which is over $100.

Nah, the bushing feels like some type of rubber or nylon. You literally just press it in by hand with minimal effort. I can't see it distorting the case in any way.
I bought one of these things and didn't care for it at all. I buffed and sanded the shaft, even hones the bushing some. Tighten up when it got hot and was loose when cold.
No advantage to having it. Bought new shaft and bushing and will be good for a long time to come.
One more thing , no matter what i did the bushing would rotate in the inner primary when shifting.
