I see this is quite an old thread but I hope someone will see this. Have just fitted the Powertronic to my 2018 Stealth Black classic 500. A couple of issues. When trying to use the supplied replacement relays, the bike runs fine in neutral but cuts out the moment you put it into gear. I have had to put the standard ones back in. Secondly, since fitting the unit, the ABS light does not go out. Any ideas guys?
