I have overridden it a couple of times in the past, via several stages, but with the amount of problems I already have with my system I’ve decided not to risk it again!

Not used them but Classic Speedometers sell parts and on this page say: "if you don't see the part that you need please give us a call to discuss your requirements."

When you fill it with oil kick it over (plug out, not on any stand) until you get a return (best get someone else to kick it over, suggest a teenager).

Re: B44 Speedo

Jerry T, the ratio is stamped on the brass ring that retains the gubbins in the gearbox. Remove the gearbox from the back wheel and you'll find it. It may be worn off, so you can gauge the ratio by turning the drive and counting the output revs....

Re: Better OIF Damper rod piston ring

If you fit an emulator, won't that take care of the damping so you won't need the original valve and O-ring?

I recall a square cross section fibre ones, L&P Williams stock them here, but that is $33 for a pair of glorified O-Rings!

The speedo mechanism is basically a magnet spinning in a cup. The cup is connected to the needle and is returned to zero by a spring. When the magnets turn they drag the cup (and hence the needle) round against the spring. You can get awesome acceleration if the spring breaks! :ban If the cable is n...

This is where the oil should be in the gearbox: http://www.b50.org/phpBB2/download/file.php?mode=view&id=10259 and it takes about half a pint from memory. Rather than mess about, drain the oil and put in just less than half a pint, leave it on the centre stand, I don't think it will leak. Your level...

Maybe your gearbox is too full, I don't think the level should be so high that it leaks when vertical.
