I took my banshee out yesterday and it ran bad. It wouldn't get into the powerband. The last time I really rode my banshee was in early January. I think the gas in it is from December maybe November. I took the carb apart and cleaned it, it wasn't gunked or any thing. The spark plugs were awful so I put brand new ones in but no change. It started on the 3rd kick, idled fine but there is no top end. It kinda cuts out right where the powerband should be. I haven't touched the jetting, changed location, and there hasn't been a temp change really. I have had the same jetting in since October 2006 and it ran great all seasons. If the gas is stale would it cause this problem? What else should I check? Both pipes get hot so I am pretty sure it is running on both cylinders right? I have no time to look at it until Thursday. I am first going to buy some fresh gas and then take it from there...maybe I will check the spark on both sides and the compression
