Or how about this?
Owner of business Werner is pretty clued up on Honda spare parts compatibility.

MrDavo:
Thanks for your replies. Below is a picture of the shaft, it doesn't look that bad. frankly the lever splines are in worse shape, despite it being a NOS one I got from Silvers. Clearly slipping on the shaft hasn't done it any good. Of course even just whipping the lever off wasn't straightforward, as the footrest was in the way.
James' solution looks like a good last resort cure, however I'd need to find the right screw, as well as buy a matching tap.
the-chauffeur's ebay shaft looks in worse shape than mine. It may be worth buying for the pizza wheel in the long term though, however as with all my engine internals I was lucky that my engine appears to be low mileage, and mine was in very good shape.
Of the two that ash found, the CB500T one looks in good (possibly even NOS) shape, however with a slightly different number (040) I'd need to know it fit, as I found with the oil pump 'con rod', even a slight difference can lead to unforseen issues. I may search the twins forum to see if I can find out. Not sure if he posts to the UK as the ad is all in German. The other one, there's only 1 photo it isn't clear whether its any better than mine. I don't do welding, and a part that would leave me stranded if the weld failed probably isn't a good thing to learn on, though I could pay someone to do it properly.
I'm still tempted to try and cut the slot wider, as I tightened until it closed completely, but the lever still slipped.

Dave ..... Werner ships to the UK all of the time .. he is shipping me a late CB550F cam cover with the pinned shafts next week. He may even know if the 500T one will fit plus he has a lot of stock not on eBay yet (like my cover for example).
You can ask him here and may geta better deal direct. He speaks very good English and seems to know his stuff on Hondas. Much easier to deal with regarding questions on items than DK.

Sorry Dave that shaft is finished as far as the splines are concerned.
I would definitely go with the grub screw fix as a set of taps versus stripping the engine is a no brainer.
I have also fixed these on kick starts by drilling right through the lever and shaft and fitting a spring roll dowel. Worked very well and was a permanent fix and removable. Only, the rivet counters would be up in arms about a fix like that and would probably hang you.
The shaft has had it anyway so what's to lose. I know it's only a partial strip with engine staying in the frame but still a lot of work compared to a dowel.
MrDavo:
Grub screw it is, then, if Roy says its shot I'll take his word for it. It didn't look that bad to me, but he knows his onions (and Hondas).
I seem to have found a source, if so what size do you recommend? Obviously I want to get the screw first, then buy a tap. Somewhere I have the T piece part, if I can find it that is (Probably with my set of Whitworth taps, which I haven't used or seen for years).

As far as the rivet counters go, there is already such a grub screw retaining a large nut on the end of the non standard rear brake / centre stand bolt. If anyone's that picky I'll tell them to get a life (or point out it's actually a K2 in K1 clothing and really blow their minds).
