Buy a used motor, and rebuild the one you have over time, as you find the parts.

Great advice - going to look into used motor costs..... Still rebuild what I have...

Unfortunately the 550 has plain bearings on the big end. My suspicion is the big end bearings and the cam journals wouldn't be far behind because unlike the bigger Z's they run the cams direct on the head (at least I think they do). Doesn't sound good either way.

First Permanent ride the Z1R since Dec1977 (220,000km) as of June 2015
Second permanent bike 1989 FJ1200 dyno'd 140RWH, great bike.
Third ride is now the Frankenstein 1981 GPZ1100B1, 1983 fully recon motor fitted LOVE THIS BIKE
Forth my work bike FJ1200 1989 (same type as FJ above)

I would say Crank bearings, I myself wouldnt mess with it anymore and hopefully you can go back to a standard bearing and dont hurt the rods.
