Hey Again:
I am looking on ebay for some regulators...there are tons...but how do you know which ones will work for your bike?
Again, I have a 1983 Suzuki Katana 750.
BTW....this site is amazing...sorry for so many questions about the regulator...this is my first bike...just got my licenses...and am loving driving!

I didn't worry about fit. As long as they charged I could care less. If it fits under the covers and has a heat sink and the same number of input wires (three) it should work. I bought two a month ago (average about 25 bucks each) . I'm going to try to put one in tomorrow.

YOu want to find one with five wires. or a honda one with six.

Five wires.. Ground, Positive DC, and then the three stator wires.

Six wires.. ground, positive DC, three stator wires, then voltage sense.

look at your stock regulator. Ideally you'll find oen that's larger than what youv'e got. The CX500 one I put on my 550 is positively HUGE. (it's quite litterally four times the size of the stock 550 part)

Most of the differences can be attributed to plugs & mounting You could use one from a brand new GSXR if you wanted to. A reg from any three phase alt system will work

Considering how inexpensive this mod is a piece of sheet metal and a few bolts can be used to make anything fit.
