Crank case

[Kinney128]

Was wondering if I could get some info on where to find a new crank case. I purchased a bike, and am doing a full restore on it. The chain at one time blew a hole in the crank case with the previous owner and I’m looking to replace it now. Does anyone know where I can find a new or used crank case for a 1970 HONDA CB750?

eBay or Facebook marketplace. There are a couple cb750 stores online but doubt they have a crankcase (cb750supply, vintagecb750, PartsnMore, etc.).

If it isnt too bad you could patch it. Ebay will be best bet for a bare case. New ones have not been available for many many years. Might try Ken at cyclex he might sell you one. Or start googling bike junk yards. My bet is you will find one on ebay.
