Hello. Just back into bike world. Not an owner but trying to help s widow. Husband passed about a month ago. Owned a 1978 CB 550 four K. Bike has good bones but was not stored well. I am bringing it out of hibernation. Bike in basement for 25-20 years, has 9673 miles on her.
Starting the process of step by step rehab.
I has put oil on top of pistons and genially turned motor over. It turns easy but I have not yet started her up.
Will be changing oil, etc and will have her started later this week.
Going through but owner will probably sell at some point.
Anyway, I am John
