I've fitted a new battery. It started straight away, despite having been stood ( under a cover ) through all the snow. This clip just shows me starting her ( second attempt. I blame having to juggle the camera ). She was started and run for a couple of minutes before this - camera, clutch and throttle were too much - but is basically still cold so I didn't want to hold the revs too high for too long. The rattle below 2000rpm is the timing chain - it doesn't sound as loud as this in real life, its just because of the frequency response of the camera.
