MrDavo:
Another thing I decided on my test ride was that while it is all very nice having the original Decarbon gas shocks, at 70mph on the bumpy 'Isle of Skye' road over Saddleworth Moor, it didn't feel as if there was a lot of damping going on. Frankly it all felt a bit scary at times, the CL's shorter trail and higher stance probably doesn't help either.

Shocks listed for the CB450 and 500T also say they fit CL450's, whether the originals had a different spring rate or settings for occasional off road use I don't know.

I'll probably go for a TEC set, they look right and improved my CB750 no end, as well as being at a reasonable price. I have also seen EMGO ones that look close to the OEM shocks but cost a lot more than the TEC ones, and I have seen some not great reviews.

My originals would be great for someone who wants a show bike, using genuine OEM parts, and aren't too fussed about being stable at speed.

MrDavo:
The splines on my gearshift shaft are shot, the pedal (new) is slipping on the shaft. No doubt the offs that cut a nice arc with the gear lever into the alternator cover won’t have helped.

New spindles are unobtainable, the obvious solution seems to be to open up the slot in the pedal for a tighter grip. Unless anyone has a decent second hand shaft, anyone got a better solution?

Is this one in any better condition than yours?  The teeth all seem to be intact if a little worn.  AFAIK the CB and CL mechanisms from that period are pretty much interchangeable (the part #'s are identical - 24610-292-030).

Might be worth picking up anyway for what's known as the pizza cutter selector part shown prominently in the fourth image.  Those things are the main weak point of the 450 gearshift mechanism and when they go, finding gears gets very hard.  Decent ones are very hard to come by now.

Dave - only other suggestion I thought may work would be to drill / tap a hole on the underside of the gear lever itself and use a cone tipped grub screw to provide a bit more ‘grip’ on the shaft. You’d probably also need to run a drill tip part way into the shaft to provide a seat for the cone. Might be a bit convoluted.?

AshimotoK0:
Will a CB500T one fit ? it's a 292-040 part?

Could you take a shaft off another model and weld it to your existing mechanism?
