This is my second go at this, so not off to a good start.
Anyway, I've just bought what I think is a CB550K3, but mine was first registered in 1979 which is a bit odd, it also seems to have F exhausts fitted to it.
Chassis number - CB550K2025730
Engine number - CB550E2026451
The bike is in a terrible mess and is in need of a full restoration, I'll get some pictures of it the next time I'm over at my lock-up.
In the meantime, I'll be around asking questions and generally making a nuisance of myself.
Cheers
Andy
