So I've had my 1980 xs650 for a couple of months, After rebuilding the carbs, replacing coil, spark plugs, caps and wires she's running good still a little tuning but I'll get there. Also I adjusted the valves and cam chain. When changing the oil I noticed the black plastic chunks and a small amount of aluminum shavings from the front cam chain guide. I plan to replace it in a few months, but right now the tensioner is set with the recommended 1-2 mm of movement. Was wondering if it would be smart to loosen it to say 3 mm to help reduce front guide wear? The only concern is jumping timing or the motor running poor with a loose chain. Is this something you would try, or should I just run it as is. Also after aluminum shavings show up how long before it completely destroys the front guide. Is this something that will last a few hundred miles or a few thousand?
