NATURE OF RELEASE: Interchangeability of exaust pipes MODELS AFFECTED: 1971 Interpol and machines with special low level silencers DISTRIBUTION: Worldwude (General) EXPLANATION: With the introduction of the 1972 Interstate model, an exhaust system has been produced which closely resembles that fitted to Interpol models and is designed to facilitate the fitting of pannier equipment. To commonise on one pair of exhaust pipes and thus facilitate spares supplies we shall in future supply L. H. exhaust pipe 063299 in lieu of 062545, and R. H. exhaust pipe 063240 in lieu of 062546.   ACTION: When attempting to fit a replacement exhaust pipe of the later part number to a 1971 model, abbreviate the inlet end of the silencer by 1/2 in. (12. 70 mm) and extend the slots to allow the silencer to clamp onto the exhaust pipe. This modification does not affect noise levels. January 1972 Norton Villier Canada Limited
