I just installed a #8 slide. There is a lot more room around the "shroud" where the main nozzle is. It seems like it would slow air velocity around the nozzle quite a bit. Anyway, it idles pretty good in the garage with almost no bog when I wing the throttle. I'll take her out tomorrow and see. I have been all over the board on jetting but this is my current set-up that should work.
PJ: 40
MJ: 172
Needle: CCK(2)
Air screw: 1-1/2
Slide: 8
I'm very hopeful this will be the ticket for my '03 250.
