Electronic Tachometer 6 volt positive ground

[jefrizzell]

Is anyone out there running a tachometer on a 6 volt positive ground BSA A50?  Information is clouded at best.  Is it possible to retrofit a mechanical tachometer on a 1963 BSA A50?  I only see the output for the speedometer, which is being used.

thanks

Several BSA unit twins had tachos, You would need a parts book for a Lightning or Spitfire to work out what parts are required.

If you don't have the needed one already you need an inner timing cover. As ever, google is your friend and all the bits are on ebay.

When I dealt with A50s electronic rev counters weren't invented, but then  again fat ol slugs like A50s never needed one
