Tonight I installed my ESR pipe and airbox eliminator but I'm worried about the jetting for Dumont which is where I mostly ride.

A friend who also runs the ESR pipe and airbox eliminator said to go with a 178 main, and a 45 pilot while putting the air/fuel screw at 2 3/4 turns out....

ESR Recommends 178main and 48pilot with 2 turns out on the air/fuel screw....which my friend said I would be running rich at Dumont with....

Since the parts desk at my local Yamaha dealer are retards and gave me the wrong 45pilot jet, I went with the 48....and 2 1/2 turns out on the air/fuel screw...

The only other thing that may affect this is that I also installed the ncvq needle tonight on the 4th clip down....

I'm a newbie to all this so any help would be appreciated....
