Got her running and she starts with one kick but there's a weird hissing sort of sound. I have to feather the throttle to get any rpm increase and if I don't do it gently enough it does what's in the video. Sounds kind of like an air leak? When the bike's off and I let the throttle go to snap back to idle there's an audible "pop" sound of the throttle sealing, I don't know if that's normal or not either.
