BOYER IGNITION XS650 YAMAHA MICRO POWER - BLUE MODULE - USE WITH SUPPLIED COIL

This is a Boyer-Bransden Micro Power electronic ignition kit, the blue-module version, made for the Yamaha XS650. It's not a Triumph part - we carry it because plenty of XS650s pass through the same garages as our unit twins, and Boyer kits like this one are a common swap on kick-and-points bikes across brands. The kit comes with a coil, and the catalog description is clear that you're meant to run it with the coil supplied in the box rather than mixing and matching with whatever's already on the bike.
