CB750K0 Carburettor Problems
Bryanj:
Does this have the 4 into 1 throttle cable? If so they were always a pain to set up and the cables frequently bind up giving wierd balancing problems, i don't know if new cables have been fitted or are available but that is one, expensive, thing to try

"yes I have, on my cb750 f2" but it was related to the spark plug cabs which were shorting out badly and was only spotted
by my son after numerous wild goose chases,....definitely worth a look for sparking in that area.
hope this helps,.terry
should add that 4 new plug caps fixed the problem and bike now runs superbly

+ 1 ON THAT I have also found what i thought to be a carb problem to be a coil related problem, i could have sworn it was carbs by the symptoms

+2 on that. Worth pulling the plug caps and putting a multi-meter across the plug caps individually and across the pair of ht leads from each coil to check the impedence. Should be 5kohm caps and 15 on the coils

Are your carb to cylinder head boots the original items? As we all know, 40+ year old rubber goes really hard and doesn't seal very well. At 30 squid a set, it might be worth a try if the advice on previous posts doesn't work. As these symptoms are normally an air leak issue, might be worth a try.
