Have some cocktail shakers on the way for my 05 Speedmaster. Also ordered a K&N replacement filter, was going to gut the airbox and remove the snorkel, and remove the AI system. Using the Dinqua's jetting calculater, there is no cocktail shaker option. Not sure which existing exhaust on the calculator they compare best to. Playing around I found myself between 132 and 137.5 suggested main jet. I ordered 135's figuring I would be safe right in the middle. Suggestions?
