I have a 2003 Predator with a Big Gun Race series slip on w/SA, drop in K&N filter, and have just installed 4 Uni Vents to the stock airbox. Before I installed the Uni Vents, I was running a 155 Main jet with the needle on the second notch. I was curious to see if anyone knows about re-jetting at this point? And if necessary what would you recommend going up to in jet size? Would a 160 main be suffucient?
