I seem to recall a post about this but i can't find the darn thing so i'm sorry if it's a re-post.... i helped a buddy of mine change his oil last night on his 636.... we had to buy a new pan and drained the bike..... as we were disposing of the oil i always strain it to see if there are any flakes or anything inside.... as we strained his oil we found three small pebble size pieces... at first i thougt it was pebbles, upon further examination it looked like a white sort of ceramic type peices.... my first thought was the friction plate or clutch but i'm no mechanic or anything..... if anyone has ideas please help.....

 

Time to take it to a mechanic

Are you 100% positive that the container was completly clean when you drained your oil in it?
