Hi all Im new here  and trying to source out some parts without much luck.I'm in Ontario and looking for standard pistons, rings and all the bearings and a primary chain.Almost everything else vintage750 has. 78CB750K.
 Any ideas?

If you are looking for standard Honda parts, look up the part number on the fich and then google that part number.
Results will tell you if still available and where.

If there's anywhere you will be able to find stuff it is here. Look down the main page for parts wanted and post there, maybe somehting will show up.

The 77 and 78 CB750 are FOMN (freaks of mechanical nature). They had unique pistons and rings when compared to earlier models. When the time comes to freshen up the slugs in my 78 CB750, I plan to go with an 836 overbore. How did you wear out the pistons without wearing out the cylinders? I would expect that if your pistons need replacing, then the cylinders need to be bored too...

The pistons have some slight scoring on the skirts and could probably be reused without a problem bu I figured since it was all apart why not go new.The cyclinders are in good shape and so are only going to get honed.
