Mag side should be richer on a 98-99. ur plenty rich stock is 146-148.

that jetting is the base jetting recommended with the cold air kit, but those recommendations were set up before our gas went to crap. i'd find a used shelf with the 3 holes and put it back in

You mean for the airbox? So get rid of the Cold air kit, or keep it and just get a stock top "shelf" without the extra cut-out slots on top?

My airbox has everything but the 2 dividers.

On another note, I checked my pilot jets and they are all 42.5. I did notice the one on my mag cylinder (which had the burndown) had some corrosion on it? Kinda like copper pipe gets?? I cleaned it but it's kinda stained on the outside.
