A friend of mine has a CB500T and it doesn't run smoothly. Compression is good, ignition is correct. I believe its in his carbs. Has anybody had any luck with a different set of carbs...Mikuni possibly? I have dissembled his carbs, removed all jets and thoroughly cleaned and inspected. Compressed air blown though all ports, etc. I am wondering if one of the brass plugs is leaking, allowing it to run a little lean on that side. What do you guys recommend?
