Hi I've got one problem in my 01 yzf 426 . I've rebuilt the bike few months ago. Now it has about 30 hrs. I've re-ruted breather tube and today I've checked the air filter on it and found pretty much oil on it. I've took the filter off and started the bike and noticed that there is a lot of air pump duting idlig. Is this normal? I don't remember such a high air flow before rebuild. Please give me a hint. Shuld I be worried?
