Honda CB350 Twin - Camshaft Replacement

Follow along as I replace the camshaft and rockers in my 1973 Honda CB350G with a refurbished set from Common Motor. This is actually the second time I’ve had to perform this fix. The first camshaft I received had some pitting in the shaft where it passes through the oil seal behind the points advance unit which was causing an oil leak. The awesome folks at Common Motor sent me a replacement kit which is what we’ll be installing today. If your camshaft is looking a little worn out check them out, you’re not going to find a better option for the price.
