I've got a 04 fatty and im getting ****ty gas mileage, bought it used and it has sampson pipes on her.
I've been told it has a stage 1 kit on it since they are not stock pipes.
my question is what size jets are in a stage 1 kit, im running rich ans im thinkin its jetted wrong.
h.d wants me to "bring it in" and we will fix u right up !!!
so what size jets should i have in it , any clue?


thanks in advance

#48 lowspeed # 180 main

 

+1 on the #48 slow jet. Just think if you didn't have carbs you'd be spending hundreds of dollars on all these fancy FI tuners .

 

+2 on the #48 low speed jet. mine had a #45 in it and would pop and fart at stop lights, plugs looked good. Had it dynoed and put the #48 in it, problem solved. I never cared much about fuel mileage, when the tank is empty my ars is usually sore!!! Control the fuel mileage with your right hand...
