Was wondering if anybody knows is there any thing in the 03 yzf 450's oil tank that keeps oil from quickly running back down into the crankcase? I run the bike for couple minutes and shut down. If I check oil right away it reads full if I wait thirty seconds it reads half way and another ten seconds or so it reads empty. Hard to tell what my oil level is when it drains back to crankcase so quickly.any input would be much my appreciated...hoping to hear from grayracer513 as I have read MANY of your posts and feel you know your way around the yzfs very well. Thanks.
