Topic: '74 550 Engine into '72 CB500

Other than the clutch cable and bracket, are there any other modification which need to be made?  What carburetors originally came on the 1974 CB550 and will the 672B carburetors from my 1972 work.  Thanks!

22A are what came on the 74 550. I belive you can use the 672b but I think the jetting needs to be changed. Do a search on that you will find what you need to change.
