That's about right! On my 400ex Honda I did a custom built slip on and K&N with outerwear. Went from 48 to 52 pilot and 152? 178 main! DS 650, cut the spark arrest or out and K&N with outerwear I don't remember the jets in this 2001, I went up on on the pilot and like 175 main. I did have to move the needle up(clip down one groove). Our local Honda shop was installing pipes, K&N with outerwear and lowering the clip one/ going up one on main jet. They were pissed when I beat them at 280lbs. There plugs were white, most didn't want my help!
