There is a VIN number on the fork steering tube (head tube). You may have to do some work to get the title generated, but I'm sure it can be done. It is done all lthe time with "barn find" cars. You just need to go to the Washington State Department of Transportation to find out how to deal with a vintage vehicle where no title is available.
The CL is the very famous Honda CL72 (250) or CL77 (305) Scrambler. If you have a good complete one it will be well worth at least refurbishing. If it is not all corroded, it would be best to keep the original finish and patina making it a "survivor", which is starting to gain value over the overly restored bikes some do. In other words if it is fairly decent, clean it up and leave it alone. Maybe relace or redo wheeld, but if the frame and/or body parts are still good paint, leave them alone. Besides, it's just less work for you if you do.
Let me add if the bike was in your family if you can figure out who bought it and when you might be able to trace down a history of ownership to the point where it can be proven to not be stolen, which is the major concern. Heck, you might even be able to find the record of the titile and generate a replacement title from when it was sold.
KLX650C, Zephyr 550
SR500, Bultaco Sherpa T
