Every so often I have a visit to the workshop from Steve Woods, Steve is the son of a very well known racer Ernie Woods who used to ride Manx Nortons and sprint a Jap engined 1100cc V twin. The Sprinter "Thor" was a significant bike in the history of British sprinting.
I think I met Ernie Woods when he was a senior member of the NSA (National Sprint Association) and I remember it being a pleasure shaking the hand of a Brooklands Goldstar rider.
Steve always has some great stories to tell growing up with such a well known and accomplished father.
Steve himself was a very capable racer and recounts the sometime difficulty of carrying out little tweaks to his own bike that were, maybe construed as, slightly on the edge of the ACU rules for the particular class. Ernie by that time was a top ACU Technical Representative and Scrutineer.
