Thought I would start a thread on my bike, I had been watching sprinting for a few years before I had a go, I took my 750cc xs650 down and got a time of 13.68 without even topping 100mph, took a break for a few years then joined the nsa and have been taking part ever since, when I first started it was on an engine I built while in Australia, 707cc and web camshaft it was quicker than the 750 engine but not by much
