So far I changed oil and filter 3 times on my X. When I change I rock bike side to side to get out all I can. Is this why I may drain more out then others, and then 4 quarts actually doesn't fill it to upper line? I just never get a satysfied reading. Once I added a little extra, I think it was 4 to 6 ounces to get it right where they want it. I know the proper procedure for checking, and even follow it with a timer. I am on a level floor, and I find the balancing point and check it after running it, then letting it sit for a few minutes. I follow checking procedure perfectly according to directions. I do it all right by the book. So, do others rock bike side to side, or do you just drain it, what comes out from the side stand without rocking the bike? I feel if I did it that way, 3.9 quarts probably would bring it to proper level. I never have tried that yet. I don't get excited after putting in a full 4 quarts and it barely registers on the stick after 5 tries because I did put 4 quarts in, I realize it isn't more then 4 to 6 ozs low , so no big deal. I do things exactly by the book, other then I rock bike side to side to get more out. What do you guys think on here?
