Shame mate, I think there are a few broken ones still. One of ours went tits at Brands but hopefully we'll get it back for Cadwell. Good luck with getting it sorted.
We are talking about 959s here @bradders but can only comment on the one I know about. Was a head gasket after it overheated following a ride through penalty. Rider did the right thing and parked it so no real damage done apart from the gasket. Not sure what happened to @Spence motor.
