earlier i took it for a ride continuing the break in, and it was running great, however when i got back to my shop and i was getting ready to turn in as i slowed down it kinda bogged down and stalled, i started back up and drove around parking lot for a few mins, then it did it again. I have been trying to dial in the throttle screw, it seemed as if it was idleing high, i turned it a little then this happened. then turned it back, and i got a back fire??? i didn't mess with it any more tonight, any help would be great. Hoping to get it figured out so I can go to Crow Canyon On monday...
