  • Damaged splines - Tricks or cures?

    So I took my wife for a long ride today on Incubus, ended up right at 160 miles. All around town. The ROT Rally is in Austin, along with some say as many as 50,000 motorcycles (mostly Harleys, still, but the population of real motorcycles grows every year). Incubus was cleaned and polished up all pretty and, as usual, got most of the attention and conversation in every group we stopped at.

    Everybody had Harleys. I had something cool. Hot chick on the back, too.

    Anyway, I installed the floorboards I scored last week thanks to a great tip from Psycoreefer. I like the look and I like they way they feel.

    The floorboards came with a toe-heel shifter. I installed it too and rode around the neighborhood yesterday. The shifter works well and I like the placement, although I think it should be called and front and rear heel shifter. But I had gone only a short way and I noticed the position of the shifter had rotated a little. It still shifted, but the position was different. When I pulled it I noticed that PO apparently had the same trouble and a lot of splines are rounded.

    You can see from the pictures that this pedal does not have a pinch bolt. It has only a set screw, and that does not line up with the groove on the shift shaft the regular shifter pedal bolt fits through. I can torque the set screw some more, but I don't think tightening it that way would give me the confidence to take the bike far. I used the stock shifter for the ride today and shifting with it, while not difficult, is a bit awkward without the pivot of the stock foot pedal.

    This is a nice piece (although it is a lot of metal to hang on the shifter shaft) and I would like to use it. Does anyone know a way to improve the grip of the rounded splines on a piece like this?

    you could line the shifter up on the shaft and drill a small
    hole part way into the shaft so when you tighten the set screw it
    screws into the hole you just drilled. jat

      One idea and one crazy idea

      you could drill a hole to seat the set screw in, or go real crazy and weld it on in the right position no way for that puppy to move then. Down side to welding is you may need to remove it to work on bike.

        Perhaps you could cut a slot into it and put a pinch bolt in like the rear brake pedal uses??

          Shifter splines

          Wrap a piece of steel screen around the shifter shaft. Then, tap the shifter on. Tighten the set screw, and report back! Works for loose handlebars also.

            This would be my choice, but I'd also get a different set-screw with a point on it. That way you only need a dimple, not a hole. Try your local hardware/parts house for the screw...

              this happens to a lot of equipment at work. we drill a small hole through the lever and shaft. then us a roll pin to hold in place. you use a drift pin punch to remove. this is a good, solid, and non damaging repair that anyone can do. you could drill an 1/8" hole and never have to worry about it again.

                If you are careful drill a hole for a roll pin.

                  My 80 came with the boards and shifter. I really like them. I have another set screw at 45 deg and it works. I found that locktite helps to keep them from vibrating out. A roll pin would be more secure.

                    For the time being I am trying the steel screen repair. Put it in yesterday and took Incubus for about a 30-mile ride today. So far, so good. I have a 50-mile trip tomorrow that should be a better test.

                    I wanted to try something that does not do anything to weaken the shift shaft first. I seems strong to handle a dimple or a small hole drilled through it, but this toe-heel shifter is solid stainless steel and it has some heft to it.

                      Boards????

                      huh?

                      Pictures, PLEASE?

                      i'd like to see them.
                      do they move the mount points at all?

                      I'm 6'1" and the pegs are not working for me.

                      Thank you!!

                        This is what the boards look like on my XS11, Mindwebs. They mount to the motor mounts. The rear mounts on the same motor mount as the stock pegs. The front mounts to the lower frame mount bolt. These, however, were made for an XS11 back in the day. I have contacted the manufacturer looking for replacement parts and they tell me the floorboards and the replacement parts have not been available for decades. They still make floorboards for Goldwings, and the floorboards themselves are pretty much the same (Emgo makes a clone for Goldwings, too), but the mounts would be very different, I believe.





                        BTW, I do not think I trust the steel screen repair. The splines are too worn and the fit is too loose. I think I'll be trying the pointed set screw thing next. I have a spare shifter shaft from the parts motor if I mess it up.

                          Very nice looking bike!!

                          very cool floorboards!

                          do they reduce cornering capability?

                          also the roll pin fix idea is about the strongest idea.

                          thank you for loading pic's!
