I'm new to this forum and the Yamaha XS650. I am more knowledgeable about the 2001-2015 Triumph Bonnevilles. I recently helped a friend get his 1977 Yamaha XS650D running. We have noticed that more often than not, there will be a noticeable loud rattle for a second or so after the engine engages and starts running from an electric start. Sometimes it does not do this at all. I am wondering if it is possible that a solenoid controlled gear is not being disengaged quickly enough after the engine fires? I've looked through the forum for this specific issue and not found anything quite like it. Oh, and yes, we have adjusted the timing chain tensioner according to the manual. The sound does not seem like it is connected to that. Any experiences, thoughts or suggestions?
