I'm at wits end I haven't happily ridden my 750 in over 3 months. I've tried somany different thing . I Want to run my 76 cb750 with a kerker 4 into 1 with the stock air box.. with stock keihin slide carbs. I tried the 105 mains way to lean. Then I tried some 110 mains still same no power and an awfull gargling noise from the exhaust. Then I installed some 130# main with the stock air box and she dumping black smoke. Does any one know where I can get a reasonibly priced main jet kit other than cb750 supply.com they r out of stock and wont be reviving any for a couple of weeks. I'm open to suggestion

How exactly are you diagnosing a lean condition?
