Thanks for reaching out. Our XS Charge PMA/Electronic Ignition kit is an easy and reliable upgrade from the old, stock TCI ignition system found on the later XS650 models (1980 - 1984). It can be installed on the early XS650 models, as well.

Be sure to read the description to see if this kit will work for you. Note: The PMA kit is NOT compatible with lithium batteries or any other lithium products.
