Just bought this bike today, started fine at the dudes house. got home... parked it turned it off. Family came out to see it and when i went to fire it up it sounded like a blender with ice cubes in it. tried it again, same thing... i'm assuming a wore out starter gear is the problem because after a few attempts it now sounds like the starter motor is spinning with absolutely no resistance from the engine (and the engine is not turning)... but I just got it and I don't know where the starter is. A detailed description would be appreciated, or pictures/links the will show me where it is.
