Hi, Just to remind you, my stock jetting on my 88 KDX is horrible. I constantly foul plugs on cold start ups. Have to much smoke and to much spooge. My stock jetting is Main 145, pilot 48 and needle p-3 (middle), a/s out 1 &1/2 turns. I just put in a 45 pilot. It starts better now w/o fouling but boogs in mid and high rpm's (while rideing). I turned the a/s 2 out and it seemed to get a little better but still no power over 1/8th throttle. My mid and top end use to be great. What should I try next? I have stock exhaust, DG silencer, boyesen power reeds. I'm still running the B9ES plug. I have a couple new B8ES ready to go but am afraid they will foul.
