CB 500 resurrection

[gary123]

 After being retired for 2.5 years I've run out of house projects and my other bikes are relatively modern so I needed a project and this seemed as good as any.
 I'm really not sure exactly what I've got so any and all comments would be very welcome. [ Guests cannot view attachments ]

The rolling chassis is a UK model CB500 four K1. The engine you show is a CB550/4

[gary123]

Are you sure? [ Guests cannot view attachments ]

Unless I'm mistaken, the photo of the engine on the bench isn't the same engine as you have just shown the number of. That engine number probably makes it a 1973 K1.

The first photo is from the for sale ad, the second is in my shed but its the same engine.

Ah, OK. So it's still looking like a 1973 UK model CB500/4 K1. It should look like mine 😊😊😊😊

IIRC when this appeared on this forum there was a 500 and a 550 engine. The one on the wooden shelf is a 500, you can see the pushrod seal and it has the gearbox drum retaining bolt on the upper casing, which IIRC the 550 doesn't have.

My bike is listed as black on the v5 but it came with a nos brown tank and panels and thats how I remember them from 50 years ago.

Yes , it also came with a 550 engine, not sure why, and as the previous owner sadly died last year Ill never know.

He was most probably going to put a 550 engine in as the 500 is toast. Years ago a lot of owners changed there engines to 550's as, they thought it was a more powerful engine with 50cc more. The 500 and the 550 are the same BHP so, no benefit from a engine change.

The UK CB500 only came in Black, Gold or Brown.
