That sounds like what we have been doing this weekend at the Beezumph, a club (TR3OC) organised event that is a bike rally with track access on the Friday. Not racing but you can go as fast as you like and there are some really nice bikes at these events.
The track last weekend was Cadwell park which is one of Britains best tracks for most, they even run BSB there. I have done a bit of video for you to look at (sorry Nigel, one got past
). Just after dinner there was a small parade which included an MV 500 3 cylinder as ridden by Ago, a couple of Trident based bikes, a space framed Norton and an ex Carlos Checa world super bike, that last bike is what I am chasing in the vid, why it was out with us I will never know but nice to be on track with it. Good job Carlos wasn't on it though.
I know it isn't racing, but the enjoyment factor is high.
Home made and very trick, notice the concentric chain.
Metal Malarky, Just right. No isolastics.
When we got up the next morning, it was like stepping back in time, the classic sports car meeting for the weekend was in full swing, I didn't know most of this stuff was still around let alone being raced. The place stunk of money though, and they were dropping oil everywhere, If the commentators were to comment on the oil they would have said it was a poor show, not that it would have been on their radar, at one point they were trying to justify £30 corkage in a restaurant, and this was over the tannoy. Nobs.
There was a full grid of these things. This one was pissing fuel because the float was stuck, that is how it went out.
Home made, 4.2ltr V twin, 1800 max rpm (Google Thunderbug Car)
Who knows
Don't know what this is either. Nice though.
