1) The bike must remain in stock form from the intake manifold to the exhaust port, and all engine parts between those two points. All engine parts (ie. cylinder, cylinder head, piston, rings, rod, etc.) must be OEM for that year model.
2) Intake manifold is defined from the rubber boot clamps to the carburetor. No porting or headwork allowed.
3) There are no restrictions on pipes or mufflers other than the fact that they must meet the sound rules.
4) CMRC will be conducting random engine checks throughout the series. CMRC will have a cylinder, cylinder head and piston from each manufacturer for comparison.
5) Any bikes found to be modified will be excluded from the results of the day’s competition.
6) Additionally, a rider may not switch from a two-stroke to a four-stroke or visa-versa. The type of machine on which a rider begins the series is to be used to the completion (ie. Start on a two-stroke, finish on a two-stroke).

But for the record, I have always been a fan of letting the 250 2 strokes race in the 250 class. Those rules you posted there sound spot on. Props to Canada on that one.
