Well, here I am again! My ride just developed a strange noise and I'm not sure where to start. Of course I am limited to some degree since I live and ride in China. It started out as a small sound on deceleration. A slight rattle at deceleration which at first I couldn't tell if it was at the exhaust or in the carburetor. Over the last few weeks I have noticed several things. First of all, the sound is not there at all until the ride is up to maximum temperature. Say the first ten minutes of riding it is not there at all. After the ride is good and hot it still may not be there but then suddenly as I come to a stop light and start decelerating there is a pronounced rattle which may stay consistent or after a few accelerations and decelerations it may go away. The next thing that started this last week is even though before I only heard the sound on deceleration, I can now occasionally hear it at normal speed and standard power... neither acceleration or deceleration. I hardly ever hear the sound on acceleration. My best guess for now is the sound is coming from what seems to be the area behind the riveted plate that covers the points area. However, due to the close proximity, it could also be coming from the push rods or lifters maybe? New oil! New plugs! Clean air filter! This sure has me worried! Another problem is that when the bike is parked and I rev it up I can't replicate the sound. Any ideas or guesses out there? Thanks so much!
