This is the second oil change I've done in the last three weeks (third change total, bike is brand new) on my '05 450 where I pulled the oil bolt from the frame and NOTHING came out. The dip stick is wet, the bike is functioning really well. Oil & filter had two rides & one race on them. Filter looked really good, mag drain plug & oil filter cover have some fine materials on them, but nothing out of spec. I filled the bike with the proper amount at the last change (I swear!!), so what gives with no oil purging from frame???
