Umm, let me see if I remember. They come stock with a 45 pilot, 180 main, and "G" needle on the 3rd clip installed. They give you an additional 48 pilot, 185 main, and "H" needle. Steve and I tried a 42 pilot, 182 main and a Honda CR 1468 needle. It was too lean, had a slight stumble, so we went back to the 45 pilot. Still a bit lean on top but since I'm not revving it to the moon, especially that day since we were trail riding, we left it in. We're putting the "H" needle back in since it is leaner than the "G" but not as lean as the 1468.
It sure made a difference. Not a trace of spooge on the silencer--Steve was kind enough to wipe the old spooge off with his pant leg when he helped me out of a small ditch I fell into--and you could tell after that it was running 100% clean. I'm going to the organized practice tonight at Seattle International Raceway and (hopefully) race Friday night. Steve's trying to talk me out of racing what he calls "stupid-cross" but I really want to do it.
