Some quick info from the gurus please

My new 1980 CB750 custom;  The only frame number I can find is on the steering neck, RC01-2203303.

Searching on this number I've found everything from this bike being a 1981 CB1000, to a 1979 CB650K.

Does anybody have a good number decoder that can tell me exactly what this is saying?  I would like to get everything, build number and all if possible.

Also, is there any reason why I shouldn't make this bike my own?  It's not a sleeper collector bike, and if I change the tank than all the hard core 750'rs will come to my house with pitchforks and torches?

   Thanks!

Well I don't have numbers right now, but most people aren't going to tar and feather you for modding a dohc. As long as you do it tastefully and do good work!

However, are you looking at the vin plate, or the stamped number, if it has 1? There should be a vin plate that says the vin, year and model. At least my 78K has all that.
