Hey Everyone, I finally got my new clutch yesterday and installed it today. Piece of cake! I checked the valves last weekend, and only one was out of spec - the right exhaust. [A bit tight.] So anyway, I put the bike back together today and fired it up. The valve train was loud - almost sounded like a "clacking" noise. Something's not right! I turned it off after about 30 seconds to a minute of listening to it. What the @#$%??? Anybody have any ideas what might be going on with the old XR600?
