I'll take a stab at this although I don't really know. The top speed of the track appears to be pretty fast. My rule of thumb is to match the top speed of the track with the top speed of the gear ra...

@meatman From what I can see in those pictures all 3 of them visually look ok.

@meatman Radical already do their own version of this that is fitted as standard to all the engines they build. If yours does not already have them fitted it is another sign that it was not built by ...

@meatman, I agree that is a great sign that it is a “Radicalized” engine. if it started life as a Radical engine it would have a serial number that started with the engine size and then a dash and ...
