Need some jetting help


Stevv

Recommended Posts

Need advice here. I just did a new top end on my 03 banshee. And I started jetting it and right now I'm at a 340 main, 27.5 pilot, needle in middle 2 turns out on the air screw. I just put the pilot in from stock and now the bike barely hits off the left cylinder and the right plug is a greyish tan color. My elevation is at 700ft. Mods are +5 timing, dune ported cylinders not sure who did it, cpi pipes in frame sb,stock carbs with k&n pods. Compression around 165 with chariot cool head and 18cc domes any help is appreciated!
