well i did this last night: i changed my oil now that my bike has 3k on it and discovered what i had suspected and should have taken care of when i first got her. The break in oil was never changed.... by the original 2 owners, so the oil was totally cooked and was watery and sticky not even lubricant any more :-/ and what the F@*k did yamaha do use an impact wrench to put the oil pan drain screw and oil filter on!? i let the bike drain for about 45 mins to get that awful oil out of my beautiful bike.... then it took me an hour and 20 mins to get the effing filter off!! i ended up having to brutally pierce the filter 3 times and use a small pry bar to rotate it enough to get it off with my hands....now she's got a new filter and 3 quarts of mobil one synthetic ..... i think i should do a preliminary flush after 1500 miles but thats would be another $50 down the drain... any thoughts?
