I have just finished restoring an ’83 Heritage Special which had not been ridden since late ’05 and only has 6800 original miles. When I started the project I changed the oil and did not notice any shavings, but that oil was very dirty and I might just have not noticed any. After getting it running and riding only a about two miles on a test run I changed oil again and found what I thought was a significant number of aluminum shavings in the drained oil. Even before coming to this forum, I suspected a problem with the cam chain guide or tensioner, as I had a similar problem with another bike many years ago. I tore the bike down only to find a tensioner and guide which looked brand new, as might be expected from a bike with just 6800 miles. The only other spinning aluminum part I can think of is the clutch, but that also looks good… Any other suggestions as to what I might look at or be causing this?
