My clocks are faulty, they stay on all the time and drain my battery. Had a RE mechanic verify it now. Easy option would be just to buy some new GT535 clocks and swap them out but that would be expensive and missing a chance for some customisation.

The problem is all the digital ones I can find can only be calibrated for multi cylinder bikes and I have no idea what the speedo ratio would be for some analogue ones. Anyone got any ideas? Thanks

I think any decent aftermarket clocks will work with a single cylinder. They usually come with a magnetic pickup for the speedo which also works fine.
