Anyone had any experience with these carbs. I put a set of CR35 carbs on my 1980 CB750K. I just cant get the damn things to Idle.
 
I have CR29s on my 1980 CB750F DOHC.
I do not use the choke to start the bike. It runs super rich on idle. Fouling plugs if I get stuck in bad traffic. I have a couple sets of pilot jets to try out but haven't had the time. It's great on the freeway.
Try a 100 or 110 main jet. Wont help the idle but who knows.
 
35's are way to big for a stock 750, you should be in the 29 range for stock. If you keep them you will have to start playing with the jet sizing to get it close but you will more than likely not get it perfect with that size. 35 are for high performance over 1000cc motors.
