Hi,
I just picked up a long awaited 1974 cb550 about 2 weeks ago.
It has a 4 into 1 and is all original apart from the pipe. It came with 25,000 miles.
I have ordered a few new parts like a new lossa muffler, petcock, new air filter, new front brake pads, sump plug and washer, new cable set and some clubman bars with mirrors.
I plan on some light cosmetic mods and will be getting new tyres etc. I will need to get it tuned soon as its got a terrible idle and not alot of go down the bottom of the rev range.
I am based in the South Eastern suburbs of Melbourne.
