I got a 99 banshee that I'm having a problem with. It won't start. I tryed cleaning the jets and that didn't work. But when I put a little gas in the heads it's starts right up. If I keep the rpm's high it will keep going. But once I let it off it dies. So it must be starving for gas. Any idea's on whats the problem. I'm new to banshees and 2 strokes so I don't know much about them.
