Judging by the front disc brake, seat, exhaust and tank, I'm betting that you have a CB360 on which someone has replaced a few parts from a CL360. The front fender and side cover appear to be from a CL360 and most likely a '75 (K-1).
Because they followed the ever-great 350's with little in the way of improvements, the 360's suffer from a less than positive reputation. Add to that the six-speed transmission and cam chain tensioner issue and they become a hard model to appreciate. That said, with the tensioner update and proper tuning/maintenance they are an entirely enjoyable ride.
If you intend to keep the bike, it is well worth performing the cam chain tensioner update. To begin, go to the engine serial number box and look for a colon (two dots) stamped somewhere within the number string. If it's there, the update was performed by a dealer at some point and you should be in good shape. If it's not, chances are you have the original tensioner setup and it should be replaced. The chain will eventually start eating the engine case if you don't and nothing good will come of that.
I have a pdf. copy of the Honda factory modification procedure that I can email to anyone who would like it. The file is too large to post. I can also provide the name and part numbers of the three parts required for this procedure. They are generally available, if you don't mind searching a few old suppliers. The update can be accomplished with the engine in place, although it is somewhat easier to do with the engine removed from the frame. The procedure outlines how to do it with the engine in place.
Best of luck...
