I would also say your fuel mix is lean. If this is your prob or turns out to be something else, could you post your results as a lot of cb750 owners like to "free" their exhaust and "open" their air intake. If you look for new jets, bikebandit.com has sets for our bikes. They come in a mixed size set, so you will need to buy for sets.
