He was on sand highway at Glamis, hauling a$$ back because he knew he was low on fuel..... I am sure he was 4th gear motorin' both times he ran out. (main tank and reserve)

Thanks for the quick responses! I must say that I tend to agree with you and am leaning towards an airleak myself. It just seems strange that it happened when he ran out of gas. It could just be a coincidence but the timing of it all just got me to thinking, so thats why I asked. Thanks for letting me know about draining the bowls...... I will talk to him about that. It does have pipes, air cleaners, light port etc. and yes it is a fuel hog. (That's why he ran out of gas) LOL

First post here and tried a search but all of my search words are too short so I need to ask the banshee guys here. I have a buddy that just rebuilt his banshee a couple of trips ago and it has been running awesome. It is a 4mil with a few mods but nothing real radical. Been running great right up untill..... he ran it out of gas. One cylinder plug looks great, the other...... white with what he explained to me sounded like aluminum. Sounds like he popped a hole in the piston but not sure, we will know later when we pull it down. Bottom line is, can this happen from running the bike out of fuel. Can the one cylinder keep getting enough fuel to run and not the other.... causing the other to go lean?? He said it was running like crap at the end, I wonder if that is when the one side was leaning out. The main reason I am thinking this way is he ran out of fuel on the main tank, bike was running great and then quit, switched to reserve, kept going untill bike quit again. Now.... bad cylinder.
