I am happy with the work and post sales support Nick at Nix speed has provided.
Fortunately, it appears that this was caught very quickly. I fished around with a magnet around the head and did not pick up any metal bits. The cam position sensor location is very close to an oil drain from the head so I think that what little that did break off just went straight down to the pan.
He is sending me a racerx cam position sensor to get me back up and running. I'm still not even in double digits for break-in miles, I'm looking forward to racking them up soon here.
