Ok, So as I was about to order some 115 mains for my CB550 (free-flow race exhaust and k&n pod filters) I noticed in the K&L Supply catalog that there are Primary and Secondary mains listed for the CB550's. What size Primary should I go with? I have been told to start with a 115 secondary main to get things close to correct before it goes on a dyno for a full tune. Any help would be appreciated; I am in a hurry to finish this bike and actually sold my CB360 to help the project move faster!
