Member Contributer Fritzer Posted September 26, 2022 Member Contributer Share Posted September 26, 2022 The shifting lever on my machine is in a position that requires my foot to be raised higher than is normal for me to shift into a higher gear. Once in a while I don’t lift the lever up enough and the gear engagement cogs don’t get fully meshed. When that happens, it pops out of gear while under load. Very bad. So far no serious damage has happened (I think/hope). The most likely solution is to move the lever one notch down on the shaft splines, but the result is a 25mm drop in the lever. I tried that quite some time back but it caused too much toe contact with the lever. Never gave the issue much more serious thought until today while doing some cleaning. It came to me that if I could not lower the shift arm at the splines to the correct height, I could increase the diameter of the shift arm pedal rubber to effectively lower the contact point to my foot. Happened to have some ¾”ID clear tubing handy so I cut off 30mm length, slit it lengthwise, wrapped it around the shift arm pad then zip tied it on. This dropped the contact point about 4mm. I took her out for a spin and what a difference that made! Now when I go for a upshift, it solidly goes into a full engagement without having to make extra toe lift effort. Now that I know this setup works, I’m going to move the zip tie ratchets forward to eliminate contact with my shoe. If a person needed more drop of the lever arm, some thicker walled radiator type hose would probably work. I am sure that some others may have the same issue. Hope this helps.

Member Contributer bmart Posted September 27, 2022 Member Contributer Share Posted September 27, 2022 A creative solution. 25mm/spline seems like a lot. I never measured any of mine. Quote Link to comment Share on other sites More sharing options...
Member Contributer JZH Posted September 27, 2022 Member Contributer Share Posted September 27, 2022 Silicone hose is very thick-walled. It even comes in black. Some experimentation could find an ID size which fits snugly without slitting or zip-tying? Ciao, JZH Quote Link to comment Share on other sites More sharing options...

Member Contributer Fritzer Posted September 27, 2022 Author Member Contributer Share Posted September 27, 2022 Picked up a piece of 3/4" radiator hose at the local auto parts store. It fits nicely over the lever without cutting it lengthwise. Put a zip on it to stop from sliding off. Quote Link to comment Share on other sites More sharing options...

I never measured any of mine. 28 splines equals 13 degrees by 92mm throw is 22mm. I was a little long on the quote. I am surprised how much better my shifts are now for such a small change the hose made. Quote Link to comment Share on other sites More sharing options...
Member Contributer Dangeruss Posted September 28, 2022 Member Contributer Share Posted September 28, 2022 I put an Aprilia shift arm on mine. It had the same splines and an eccentric adjuster on the tip. It was a bit shorter, which increased effort a bit, but the improved ergo was worth it.
