2012 CRF450R Oil in Airboot
Posted 11 October 2012 - 03:09 PM
I have a 2012 as stated and it is right at 30 hours. Used correct break in procedure and changed oil ever 4 hours engine and tranny.
I went to change my airfilter before practice and the whole bottom of my airboot had a layer of oil the whole way across it. so i cleaned ot the oil and changed the filter and went and rode some more and it happened again?!
What could this be, my suspicions could be that i have a FMF rct 4.1 and a megabomb with out mapping causing to much blowback? Or could it be that a valve seal is out or a possible injector?
Anyone else have this happen or know what it is?
thanks ahead of time for any replies

There is a vent on the top of the valve cover that vents directly into the airboot, before the airbox.
When you reach high rpms you push up the oil pressure, and the oil has to go somewhere, if there is too much....
Mapping, injector, pipe, have nothing to do with it.

I always check my oil level before i ride and it was perfect both times so im not sure what it is. Would that harm the motor in any way though to be sucking oil? I was going to race it this weekend but if its going to end up worse ill just run a smoker
What do you mean you check your oil level....with the dipstick?? That's about + or - 15% or so.
You have to measure it in, and get the motor HOT when you drain it, and kick it through 10 times to get it all out.
