I have done the same as Minority and I'm sure I used a Oil Level plug as fitted to the chaincase cover, hope that helps.

Thanks Andy, but the oil level plug is a bolt, right? I think Minority is talking about a spacer nut, or am I missing something?

Yes it was just an ordinary nut that happened to fit over the axle and was about the right thickness. Unfortunately I have no idea what size it was, I just found one in my box of nuts and bolts that fitted.

Thanks - and there was me thinking that I'd need a special "MBD CNC-machined stainless speedo drive spacing system" ;)

Ahh I see what he's done now, can't see pics on works computer. I thought he had removed the speedo drive and blanked off the hole the brass piece and worm drive fit into. Sorry about that.

So, if I swap to mph it also displays F... Any way to keep C as temperature?

Or do I have to manually reprogram the kmh speed to show mph if I want Celsius?

You have two choices as standard, MPH/F or KPH/C.
If you want MPH/C you will have to mess around with the tyre circumference to fudge it as you suggested.
In theory if you set to KPH/C and divide your tyre circumference by 1.6 (if that's within the allowed range) you should be about right.

That was my thinking to - thanks for confirming!

I've not been through all of the responses on this thread but I was having problems with my SIP speedo freezing and not starting up properly etc.

It appears that you must run a resistor type spark plug if you are running a battery-less A/C system to make them work correctly. I switched from a B8ES to a BR8ES and it works perfectly now.

Hope this helps.
