SERVICE RELEASE N49

NATURE OF RELEASE: Fitting Exhaust Systems MODELS AFFECTED: All Commando models DISTRIBUTION: Worldwide (For general distribution) EXPLANATION: If the exhaust system is not assembled correctly to the frame, it can lie in the wrong plane. The tendency is to push the system to its lowest position during fitting so the centre stand and other equipment can come into contact with the exhaust pipe and mufflers. Assembly as below will prevent both misalignment and strain on any of the fittings.   ACTION: When assembling an exhaust system. Fit the copper /asbestos sealing ring into the exhaust port, after the exhaust pipe to the port and, holding in the correct position, tighten the lockring sufficiently to hold the exhaust pipe in the correct position whilst permitting it to be rotated slightly. Now assemble the muffler to the exhaust pipe and to the muffler mountings. As the final operation tighten completely the muffler mountings, forward clip and lockring.
