Unlucky and lucky!

Been having quite a bit of what sounds like cam chain noise on my 850, (always had cam walk noise, but seemed worse) so decided today to try and check it out. Took carbs off to get cam chain tensior off and reset it, just to make sure it was working properly. Reset it properly and turned screw out alittle over 1/4 turn and locked down nut. Working fine. Noise may have been slightly better, but not much. Checked on here and some suggestions of loose cam caps were made on old threads, as well as tight valves. Took valve cover off and tightened cap bolts a little (weren't loose but not completely snug), used my HF torque wrench but was afraid to tightened too much and snap a bolt. Well off course I snapped one! But got lucky that although it was down in the hole a ways, I was able to tap on the edge with a small screwdriver and get it to move. Took me 45 minutes to get it to the top so I could grab it and out it came. Yeah!! Checked valves and only three were tight at all and they were at .03 or .04. . Will be changing those after get back from officating volleyball at Girls Inc. Any other ideas what to look at for possible noise. Cam chain seems tight, and I'm sure noise is coming from engine and not starter clutch. Oh, and get louder with more throttle. Bike is also running great other than being noisey. terrylee
