First off, I have conflicting info on the choke. The manual explains the knob that is found on the YZ motor but not the lever that is found on my WR. The manual says pull the knob up to turn on the choke, down to turn it off. On the WR, the lever up would be like the knob being down, and then obviously down would be like having the knob up. Which is on/off for the choke on the WR lever? I have been riding with it like this: lever down for choke on, lever up for choke off. The bike fired up today, but I think it may have fouled a plug. I installed my new pilot screw, adjusted it to 1 1/2 turns out, kicked it a ton of times and got it to fire up. It ran well and when I flipped the lever up (what I thought is choke off) at idle it would start to die, flipping the lever down would raise the idle back up. Rode down the street, and it was running fat in the mid range, got a good rip though the top and it cleaned up and ran well. All the sudden it bogged and died. The plug was soaking wet with gas. I can clean the plug real good and get about 3 sec of running super rich, but then it dies and will not restart. Seems to start easiest with the pilot screw at about 4-5 turns out. (again still not sure if im running with the choke on or not) The last thing is I am looking for jetting recommendations for 3-6000'. Right now it is set with a 360 main, 40 pilot, clip in position 4 on the needle and to get it to run clean before the plug fouled, I had like 5 turns out on the pilot screw. I thought after reading the manual that I ahd been running with the choke on, but the bike ran decent, although did have a pretty good amount of splooge out of the exhaust. After I got it about a month ago, I got it running well by leaning the pilot jet screw. I ran it like that for almost 200mi riding mostly 2-6000'. I rode a lower elevation area on laybor day and had a hell of a time starting the bike, but once it was fired up it ran decently. After I got home I found that my pilot screw had wiggled out (likely because of how far out it was) and the bike was too lean to start cold due to no screw in the hole.
