ah im sure rutans correct i just did a minor appearance job (sprockets , chain , brakes , seat , exhaust , choke cable , rims and skins ) never really got down to the motor or carbs , guy was selling it to a buddy and he wanted painted first so i just popped everything off and took to painters for him . His 06 is funny though i has some major issues starting when its cold . I know my 06 zx10 (fuel injected ) starts like a dream in the cold !
