Woody you are correct, there is no requirement to run the new clutch with the exception of Super 1.

Hear are the current regulations:

C2.5 Transmission: Direct from the engine to the rear axle via a single length of chain. The
clutch must be as supplied by Rotax for the FR125 MAX. The internal running surface of the clutch
must remain dry and free of grease or lubricant or any additional substance. The engine clutch must
be triggered at 3000 rpm maximum and make the kart and Driver move forward. The clutch must be
in direct drive (and 100% engaged) at 6,500 rpm. See U18.8. A bar test may also be used to test
clutch engagement, parameters to be advised.

Amendments to Gold Book 2011: The MSA have approved on 25.11.10 the following amendment to the Rotax class 2011 regulations:
Transmission: Direct from the engine to the rear axle via a single length of chain. The clutch must be as supplied by Rotax for the FR125 MAX. The internal running surface of the clutch must remain dry and free of grease or lubricant or any additional substance. The engine clutch must be triggered at 4000 rpm maximum and make the kart and Driver move forward. The clutch must be in direct drive (and 100% engaged) at 6,500 rpm. All sprockets must use a 15x19x17 needle cage bearing and O-ring seal except in the case of an 11 tooth sprocket. An 11 sprocket must be fitted with a plain bearing with or without an O-ring seal.
