I was in the first heat of a snow cross race and she started missing and died a couple of times including going up a 45 foot tabletop. when i changed plugs it showed that i was running lean but i just had it rejetted and it was fine three days before. im getting plenty of fuel at the petcock on the tank. Hopefully its nothing serious i have a race in less than a week. any info someone can offer will help. thanks
