I just got a 81 cb750k, its a great looking bike, but has been sitting for a long time, and needs some carb. work. The bike allready has a header on it and I´m wanting to remove the old air box and put some K&n pod filters on.I allready have the carbs off and would like to go ahead and do any jetting that might need to be done while i have them off. I´ve never jetted carbs before and would appreciate any suggestions or references on the subject, such as what size jets to use, the best place to find parts, and procedures.Thanks in advance, MM
