CRM Posted March 21, 2019 Report Share Posted March 21, 2019 I thought i would add this here as i lost all the info and it took a while to refresh my memory about how to do it. Anyway i cannot take the credit it was someone else who gave me some verbal pointers and started me off on this path. So as you know the NSR250 MC28 has the "smart"card and digital speedo and as such reads in KPH which is a bit of a pain for us here in the UK. Its pretty easy and cheap to convert and this is what you need, Get over to svaspeeedos.co.uk and order yourself a E0021 converter for £35 once you have this follow the simple instructions here (don't worry if your converter has a green lead it still works) Speed is shown in MPH and mileage will increase at a slower rate too hope this helps someone else converting a Honda Digital speedo fed from the front sprocket area. 2 1 Quote Link to comment Share on other sites More sharing options...

Mellorp Posted June 12, 2021 Report Share Posted June 12, 2021 The E0021 is not available anymore. However Buy one of these converters http://www.kbtv.info/speedo.htm Find the wires from the speed sensor by the front sprocket Trace them to the 3 pin connector somewhere close to the front of the seat subframe LHS Use the +ve and -ve feeds to power the KBTV unit The yellow wire is from the sensor The grey wire goes into the loom The green wire is superfluous I used 2mm flat pin connectors to make the jump leads That's it 2 Quote Link to comment Share on other sites More sharing options...
