[QUOTE="Simon Dinsdale, post: 45531, member: 58"] To change the atd is not simple. It involves exhaust removal, engine timing cover removal and then atd removal. Then the ignition needs retiming with the new atd and all re assembling. To check the atd function is easy. Just remove the small cover held on with 6 screws behind the front exhaust pipe on the engine timing cover. It can be removed without removing the exhaust. Then rotate the atd against its springs and release and check it returns to the stops on the atd. With small tools and patience you can even change the springs for new ones through the small cover. Just jam rag into the gaps to stop the springs dropping inside the engine when swapping. If the bike has been stood for a long time the atd may be just sticking with old oil and so going through a few heat cycles and fresh oil would help. This is all assuming your bike is running a Lucas magneto with atd ignition and not a new BTH ignition, series D distributor or other electronic ignition which does not use a atd under the timing cover.
