Electronic tachometers usually work by 'counting' 'pulses' from the coils but these bikes have 'dual fire' coils which means they file on both the compression stroke and the exhaust stroke.  Many tachometers have a switch to select 'single fire' or 'dual fire' coils, and those that don't often have an 'add on' that 'fixes' a singe fire tach on a dual fire coil.  You should check with the tach MFR.

I hope you might be able to help with the installation of a tachometer on my 800 Drifter, the unit came with no install instructions, but I used my Google-Fu skills to get it almost there...BUT! It reads 2X's the RPM's?? any help would be fantastic.
Thank you for your time and consideration.
