I ride a 1975 CB550 that I've had since 1997. Lots of good info on here and looks like a good place to hang out. I need to show my bike a little more tlc, because its been good to me. I started riding in the early sixties, first with a Zundapp 250 for a couple of months and got the bug for more power so I bought a new 1962 Norton Atlas. Other bikes that I owned in the period were a Ducati 250 scrambler, BSA Road Rocket, and 1966 BSA scrambler. Quit riding for a long time until I got the 550. I'm currently wrestling with a frozen bleed screw on my front brake caliper. I think I'll have to go with the Thegman insert, but I'll get another caliper for the interim from fleabay or crc2.
