Its a 2000 model. The bike runs fine and strong. i recently cleaned out the carb. what seems to be happening here is that the carb is vapor locked or not venting. Fuel is not refilling the supply line. The petcock is brand new and flows fine. I shot some low pressure air through the fuel line and it blew out of the vent lines. yesterday was the first day that i was able to get out and ride it, and when my issue occurred on the trail i would have to pull the fuel line off the petcock and slowly turn the fuel on and fill the line back up to get myself back to civilization. Any thoughts on what this could be? Thanks in advance.
