Hey, I was on here a while ago asking about bikes and I just picked up a CB750. It's in good shape but didn't quite run so I took off the carbs and sure enough the slow jets were clogged. Other than that everything looked pretty clean. The only problem I have now which can't find in the factory or clymer manual is the choke valve on the number 1 carb is loose an doesn't move with the other three. It stays down when I turn the choke off and I can wiggle it around with my finger. I'm pretty sure I can be riding this as soon as this is fixed so I would definitely apprecate any and all information that might help.
