I have never rebuilt a four cylinder bike before, I have only done singles and twins, so I thought it was time for a four.
I have just purchased a 1980 CB750K dohc, i say its a 1980 but the engine number has been messed about above with so could be later, its had 22 owners so is in a bad state with bodges all over it.
I have done some work and restoration and it runs well until its gets hot then the tick over is erratic and then cuts out, also the revs are slow to run down.
All the books and manuals say it should have VB42A carburetors this has VB52A(no accelerator pump) with 68 & 102 jets, would welcome comments and thoughts on these carburetors being fitted
