That said, on the whole, can't help thinking it's all a bit daft. My Cat SX shell has the std air vent removed, it measures in the region of 11.5x16, and now that shell isn't legal...... You'd have to "try" and put your finger through it.

Roger, yes, it's hotter in a lot of parts of the world - but a lot of the time, they are running on dirt, with a lot less load on the motor - hence, doesn't generate as much heat internally.

love it so whats the cowin rule in english please
