Found this cool link to this motorcycle electrical connector site on a moto guzzi list I'm also on so I thought I'd share it . Looks like there is lots of things that will work on K bikes .
Electrical Connectors Here

Lots of Royal Enfield connectors in there too (Sumitomo). I'm pretty sure you know'll this, but just in case, Guzzi OEM terminal blocks are Molex 0.093" series.

Yeah , My electrical connections  on my 850-T melted one day while out riding  a good 7 or 8 years ago (molex) . The starter just started to try to start the bike on it's own as I was going down the road.I was able to tape it up and get home where I got rid of those connectors going into the headlight and set the whole thing up with bullet type individual connectors. Never had a problem again after I did that.
