just changed the oil,first time on this 06 yz450. i just got it.. i changed the oil and filter,let it all drain out best i could from both drain plugs. put new filter and oil in.manual called for 1.2 quarts.added one full quart adn about 3 or so oz or teh other. was just a tad bit over the xxx's on the dipstick when i stuck it in and checked. i noticed today after a good hard ride around the block,after i went back out into the garage there was a small pool of oil under the bike! i traced it from the hose that runs down from the valve cover.just wondered if it was normal or ok for that? did i add way to much oil?
