Yes this is the right place for great information.
We have a lot in common, I also have a non running CB 500-4 (it was free!) and it is my 1st street bike too. It's good to see another dirtbiker here, I ride a 98 YZ125, brrraaaappp!
You may find the CB to be a bit overwhelming (I certainly did) to rebuild, so many parts compared to a single cylinder 2 smoker but they are fairly easy to work on. Good luck on your build. If I can be of any help just ask, I recently finished my CB motor rebuild but I'm putting the rest of the restoration off for a little while so that I can get my YZ ready for spring.
