1 -62 BSA. Tank buggared, Carb buggared, Magneto buggared, primary chain and clutch buggared, Cylinder head manifold cracked, Electrical buggared at the factory. 432 (est.) case leaks repaired.
2- 74 CB550. Bought as salvage after nasty crash, motor, and triples unbent, everything else bent and replaced or straightened, including frame Had to toss the case guards. But, they did their job.
3 - 75 Cb550F. Bought as parts bike, tank and carbs corroded unusable. Few parts work as spares for the 74 K. So, I collected more parts to make it back into a runner, still needs tires and fork seals, though it is drivable.
4 - 77 CB550F. Sat in garage for 15 years. 8000 miles on it. I saved it from going to the junk yard. Tires, carbs, battery, chain/sprockets, brakes, fork seals, and a whole lot of cleaning/polishing, made this one of my best bikes.
5 - 76 CB550F. Bought from wreckers for $300. (I was just looking for parts!) Wire harness burned/melted, rectifier destroyed, Chain/sprockets, carbs, sprockets, battery, tires, seat, brake rebuild, factory new side covers, and replacement cam cover and cam.
6 - 78 CB550K Previous owner had the bike stolen and stripped. A year later he decided to sell it as it had been parked in his carport (a roller), untouched. I found/bought all the missing parts to complete the bike and restore to roadworthy.
7 - 75 Cb550K. Was an abandon bike. Some dumbass tried to convert to cafe style by throwing away lots of parts, but still had King queen seat!? Tank internal rust, outside of tank already repainted, carbs sedimented, clutch would disengage with sharp left turn due to short narrow bars and very bad cable routing. Cam cover/cam wear issues, electrical corrosion issues. Old Koni shocks frozen and too long.
I fixed the bike and made it a nice machine, rode it for a little while. I eventually sold this bike three times!
8 - 77 CB750F Another abandon bike refurbished to road worthy. Acquired for free. Still needs paint, though.
9 - 85 CB700S. Oil leaks and lots of neglect lack of repair prowess by owner. Free. Tires, starter, battery, turn sigs, windshield, carb clean. And lots of cleaning/polishing, all made it a pretty nice machine.
There are more "in progress", but aren't yet road worthy. (I probably spend too much time on this forum.)
Cheers,
