Ok, 2" snorkle, NGK plug, K&N filter, and looped the vent lines. Today is the first time I actually went riding since I put these on, and it was real hard to start cold. When we got there, we had to take off the lid to start it, and when I got home I had to do the same thing. Runs great after it starts. Now I have fuel in the airbox. Does the A/F screw need to go in or out? Any suggestions?
