Even if you do not have a battery or money for a possible bad starter you can see if the engine will turn over. I know your a aircraft mechanic. But anyhow, pull the plugs, put it into gear and turn the back wheel. Will the wheel turn the engine over? You should be able to turn the back wheel by hand or roll the bike and get the engine to turn over, if not....... More fun times ahead, now why will it not turn over, possible tear down time. Good luck let us know what you figure out.
