Yeah, that's it. I didn't win because I wasn't cheating. Actually, Meiring's bike was found to be legal and it was even faster than Hayden's on the straights.

You can machine the gasket surfaces of the head and cylinder, including the cylinder base. You can (I believe) do multi-angle valve jobs provided that the grinding is limited to the valve seat itself. All engine parts must be stock, with no modification. Carb rejetting/EFI reprograming is allowed, exhaust system can be replaced, shocks can be replaced and fork springs, valving etc can be modified.



I believe the rules are on the AMA web site but I was too lazy to find the exact link.
