Hello
I'm the happy owner of 2 CB550 F1 from 1976.
One is original in a condition "as is", mayby some day I will restore it to new condition.
The other one is a bike rebuild from scrapyard parts into a bike I like and wich is fun to drive, I call it "the party animal".
I have a site about CB550's, unfortunally it is in Dutch, but I'm working on a english version.... patience
on this moment I'm orientating how to rebuild an engine with by example big-bore and flowed head, so if anybody has experiance with these items, please let me know
grts Ben
