Rode with a buddy today who also has a turbo bike and one time when we stopped his bike wouldn't start. When we turned the ignition on we didn't here the fuel pump priming as usual so we assumed it was the fuel pump. Could it be anything else? Finally we turned the ignition on one more time and presto it made the low squeal sound started right up. When we got home all lines, wires, etc. look good. It starts every time we've tried since. Could it be a heat issue? This is stumping us and my friend is afraid to ride it until this is reconized and fixed.
