[QUOTE="ionbeam, post: 1284892, member: 277"] Replace the CCT with a new one. Any new CCT will be the updated design and work fine. There are several good 'How To' threads in this Forum, the trick is to not let the cam chain get enough slack to jump a tooth on any of the three sprockets. While not an emergency with such a low mileage engine, it's something that eventually you should get around to. You should be safe to wait until the first valve adjustment. The way the CCT is assembled it is possible to have one set with the tensioning spring tight and the next one with the spring insufficiently tight. Luck of the draw -- or not. The original CCT on my FJR had almost no tension from new. The tensioning plunger is half way extended to start with and the spring pressure falls off very quickly as it extends further to take up chain wear. [/QUOTE]
