Try putting a washer or two inside the shifter rod on the shaft. Is the shaft loose or does the shifter move around on the shaft ? May just need to bush the shaft.

The splines on the shaft are fine, it's the linkage - claw, whatever it is - that's worn. I've got a lot, make it enormous, amount of slop in that shifter. It makes missing shifts easy! However, I don't want to miss shifts!
I still need to futz with the petcock and find out why the left carb dribbles fuel out of it's vent when the bike isn't running. I suspect trash in the needle and seat. I want to run the tank low before I disconnect things and remove it, though. I have to ride the bike for more than ten minutes at a time to do that! :)
Rode a CBR250R today. Cute little bike! Just a little torquier than the Old Girl, but the Old Girl has a lot more up top. The CBR is smooth, though! I also rode a Ninja 300. Now, that bike is fast! Much faster than the CBR and the Old Girl. It's very refined, too. Nice motorcycle! Well, both are. No, all three are!
Thank you for that! The shifter splines are worn. The shaft is just fine, it's splines are good and it does not move. I've considered bushing it, but I just don't know about that.peter4821 wrote:Try putting a washer or two inside the shifter rod on the shaft.

Graham - thank you!! I have basic tools, no machine tools at all (well, a bench grinder). However, you've given me some ideas.G-Man wrote:Sarah
If you have good tools, the 'easy' way is to set those clevises up in a pillar drill and find out what the 'next' size for the hole would be - either metric or imperial to get a fractional increase.
Buy a reamer of the size you need and take the hole out to the 'next size' by drilling 0.2mm undersize then reaming. Next job is to find some material to make the pins.
Alternatively you might be able to make a Honda 400/4 linkage work with a long rod.
Or - take a look at 'rose' bearings on eBay. This is what the 400/4 used and they provide a much larger spherical bearing surface.

The above should work with your existing shift linkage rod. Just get some bolts, bolt the rod-ends to your shifter arm and shift lever and you will be good to go.....
You might try and get some rubber 'boots' to cover the rod ends to keep everything nice.
Have fun!
