Is there anybody out there?
 

I've got a (I guess somewhat rare?) 80 KZ550 4 cyl. I can't find forums on it that have been used in the last 6 years, I can't find anyone else with this bike. Anyone else ride the old Z bikes?

A 4 cylinder 550? Wow talk about piston to displacement ratio!!!

I do not own one, but congrats on the ride. I think that this ride should have stayed around for awhile with some work on suspension and brakes. No corner clearance what so ever, but would make a nice street bike. (I have the 1k, so going off of that experience)

try this one pontiacdude210
KZrider.com
its pretty good forum dedicated to KZ's of all types.
I ride a 1980 KZ750E and have 1 1/2 KZ650's I use as parts (most pieces are interchangeable, well after some messing around :) )

I had a GPz 550 in another lifetime

....just nod if you can hear me......is there anyone at home?
(Perhaps THE quintessential rock guitar lead of all time; my hands down favorite.)

Dude Jeff, I remember that album. It came out when I was 14, and in fact I played it so much that I wore out the tape and had to buy another one. To this day, its still my fav album of all time!!!
