[QUOTE="Dgaspar, post: 1372741, member: 80530"] Hi, I had the extact thing happen with my street bike and it turned out to be a blow back valve and o rings in the petcock. After a while of riding the o ring and valve affected the vacuum and fuel starvation would occur. Actually some fuel would flow but not enough to satisfy the engine. Opening the chock slightly would allow more fuel directly into the cyclinders and keep it running. Now I also had this happen to my two stroke bike as well and it turned out to be an intermittent connection in the CDI caused by heat and vibration. Very same circumstances that you describe. I checked all the fuel circuits and carb ( dealer looked at carb as well but they had no clue). Start by checking all the obvious things including replacing the caps and check timing and spark as [U]soon as the bike falters[/U]. Then check the stator coil pickup and source if all are within spec. This will help determine if there is a problem with the CDI [/QUOTE]
