Motorcycle Repair: 75 CB 750 K, cb 750, airbox

Question
I just recently bought a '75 CB 750 K and I am looking to refurbish it. It is missing the airbox and air filter, so I have decided to go with the no box, and cone shaped air filters instead. Any idea on what I should jet the carbs to? I was told that if I don't get more fuel in there it will not run well at all.

Answer
Sorry Zack, but the jets will depend on the exhaust restriction, and altitude you're running.  But it has a 105 main jet stock and a 115 or 120 main jet would probably be about right.  You'll want to raise the needle jets about .025 or .030 inches too so you don't run lean in the mid-range.  If the needles don't have clips and slots in the top, you can put small washers under the stop to raise the needles.
