Hey All. I am the new owner of a 03 wr450f and I took it for its first ride this weekend. I was running in the 5000-6000 altitute. I have the endcap removed and the snorkle out. I noticed a lot of popping after releasing the throttle and there was a big bog off idle when I went to pop the front wheel over an obsticle. Is this a sign of being way too rich. The dealer "said" he performed the service bulletin, but failed to punch the vin. So I'm guessing that he opened the air screw a couple of turns. Would this have made my bike to rich? I'm not quite ready to get into the rejet stuff, I just want to go out and ride. How can I get this to run normal at that altitute and at sea level? Can I just close the screw a turn or two? An advice for a newbie would be greatly appreciated.
