Jetting thoughts
Hi all, Ive recently fitted an andrews ev13 cam into my 1991 fltc evo, the papers that came with the cam advised a 48 slow jet and a 195 main, my bike has a k&n filter and fairly open/noisy silencers, the jets i had were 45 slow and 180 main, i fitted a 48 slow jet, and a 190 main, i already had these, bike goes well, but having read a lot of threads on the jetting sizes, i am thinking that they are to big, for my bike, would like any thoughts on this

I have the same EV13 cam in a ‘97 FLHR, SE airbox, 2-2 Kirker slip on mufflers.
I rebuilt the cv carb and installed a CV products emulsion tube... I started with a 48 slow jet and a 180 main. I changed the main out to a 185. I think the bike ran marginally better with the 180, but the motor seamed to get considerably hotter. The 185 seems to be right for me. The difference in gas mileage between the 180 & 185 was insignificant. (I’m getting 47 mpg backroad riding) I can’t recall the turns from seated on the mixture screw, but I do know the 180 required more “out” on the mixture screw to get things dialed in.
Good luck
