I appeared just after SBW merged. Hey, just an idea for you: run a magnet over the shavings (if you still have them). I would be a little more concerned if they stuck, meaning they are steel.
I change my oil every year, at the end of the season, regardless of the mileage. I store the bike with crappy 99¢ oil, and then change it to the good stuff when summer arrives.
Thanks again ! I did run a magnet over a few of the tiny particles, they were NOT magnetic in any way (aluminum I guess).
