Rectifier swap question

Does anyone happen to know offhand if a rectifier from a 1977 KZ400 will work on a 1977 KZ650c1? They both are the seperate reg/rect but the one I have from the 400 is different except that it looks to be the same wiring setup (except the stator wires are white instead of yellow)

Thanks!

Dave...post a Kawi part number and I can cross-ref it for You,Bud...jus to see what other bikes DO use the same rectifier.

I'll look at it tonight and post the part #. Thanks!

21061-31 is the rectfier part #. Used only on the 1977 KZ650B1 and C1. Other rectifiers could work, but no other Kawasaki used the exact part.

The part number will be different from minor differences. Sometimes the part number is different just from wires being a different length.

I believe the 77 400 and 77 650 use a very similar rectifier (and even a similar regulator). it may be worth a try.

You could also make one for about $20.
