hey guys, im a little bit puzzled here I ride a 2009 yzf 450 , just got it new this year in may. anyway it seems to be "burning" oil but the funny thing is that it seems to be reading good on the dipstick after a ride but then the next time i go to ride it i check the dipstick after leaving it warm up and the oil level is low and i have to add about an ounce or two of oil for it to read good on the stick agian. am i missing something here? and whats wrong with my motor? my motor has about fourty hours on it, 8 oil changes along with filter on every oil change and iv never raced the bike. Thanks to all.
