I bought a 91 VFR last year. It had a two brothers exhaust placed by the previous owner and a motorcycle mechanic. It has new pipes along with the exhaust. The bike has been running rich. We took the carbs off today and found the stock '130' main jet and the stock '40' idle jet. The only modification to the carbs that was obvious was that the pilot jet was set at 2.5 turns, a full turn over the suggested factory setting. We reset the pilot jets. I was wondering if anyone had any experience with the jetting required for a 2 brothers exhaust with aftermarket pipes and a k&n filter. Thanks for your help!
