Apologies if this has come up before. I did search the forum and didn't see anything. I've got a Smiths Speedo (Indian replica) and wondering if anyone knows where I can get it recalibrated for 10 inch wheel. I don't mind if I have to post it overseas. Everything I've read on these Speedos seems incredibly complicated. I've got a custom made headset primed and ready to paint. The speedo fits well and really looks the part, but I would like it to be somewhere near accurate in use!! Also any tips on the drive cable connection to the front hub would be useful.

remove the bottom threaded part & use a std lambretta type & these will work

Thanks for the tip re the cable connection. Anyone got any advice re calibration? There's a place in Swansea but I'm in Australia. I could post it if anyone has used them?

I'm thinking of giving up on this as it's in the too hard box. My headset has been customised and the Smiths speedo is a good fit, but not having it calibrated is a big issue. Surely someone must've had one converted or sorted. I know a few guys just bend the needle so it reads ok at a mid speed like 50mph, but this doesn't cut it for me. I'm thinking of something radical like the SIP digital conversion. Anyway one last shout for help re the Smiths !!

hi you posted on my thread about my gt240 problems asking about smiths speedos ,

mine is an original 1960s speedo and was serviced by gaggs in nottinngham mine is yet to be calibrated for 10 inch wheels costs around £55 , there is another place also in nottingham called chronometric instrument services , you could try they gave me good advice an were helpful .

not sure about recalibrating the remade ones but i went for an original as they havd a lower profile so dont stick up out of your headset top like a dalek !

Many thanks mate. The repro is pretty good and I believe they are made to original specs as part of the Royal Enfield deal, but as with Indian Lambretta, probably not to the same grade as originals. Mine looks good in the customised headset, but I really need it to work quite accurately. Thanks again.
