I took my new to me my 2000 Yz 426 out last weekend before I rode the bike I did a oil filter and oil change including the screen. The oil leave was a bit high on the dip stick just above the full line I thinking no big deal. And yes I started the bike before I checked the oil level and with the dip stick not screwed down I did notice I had oil drips comming out of the oil blow by tube under thew bike i was not to worried about it. This morning I thinking taking the bike out for a ride and checked the oil level as I normaly do before I go ride I notice the oil level about 1/8 of a inch under the bottom of the dip stick now I only rode the bike a hour last time last weekend. Is this normal for a 426 uses oil of do I have more going on I need to look at harder.
