If it is popping when you let off the gas then yes you need a larger pilot jet:)

also, i would come down on your main jet to at least a 160.

go up to a 42 pilot at least... WOW 170...I run a 146 dynojet:eek2:

i put in a 42 pilot and it is popping real bad upon decelaration. if i went up to a 45 would kinda calm down a bit?

isnt that what he just said ;)

There is no reason to drop the main jet size if it runs good on top. I run a 165 in the summer and 170 in the winter in a stock carb with a 416 kit at 3000 feet in all of my customers bikes
