Hi Nick, no not booked in for dunsfold but thanks for the offer, will quiz you on it next time we ride.
Ian, yes I have 4 into 1 collector, perhaps a 4 2 1 will be worth a try, I'm hoping some re giggled ratio's in the gearbox might help
jonboylaw, I have some kind of electronic ignition but don't know what kind (it was on the car when I bought it)
Tony
