@meatman the easiest way to tell the k7 from the k8 is to look at the valve cover. The k8’s have a plate over the top of the plug wires that has to be removed to take out the spark plugs and the k7 d...

Wow, at least you know where your problems are. My guess is that something large got stuck in the GDU gear which caused the gear to break which in turn caused the other issues. How many hours are o...

Hi @smoothcriminal, welcome to the Forum! It looks like you had a fun first day on the track. There re plenty of people here that are happy to help if you have any questions. 🙂

Welcome! It is great to meet you.

Hi @slowcar, Radical sells single seats and there is a company in the UK called The Ark Angels that offers one also. But converting to a center seat configuration is a bigger job than it seams. You ...

@kt-r13, Nigel doesn’t have these anymore.
