you are welcome to organise this through our track events.. why go out of the way to organise your own when we have them 3 to 4 times a year already.
If you'd like to organise a small 4 cylinder competition at one of our events.. send me a PM with some details and we can get something set up. We can possibly get some prizes organised.
If you do PM me about this.. be sure to have your ideas ready.. ie just HOW you want the format o run.. rules etc etc.
