Mr. Polaris Tech,

What is your take on the 850XP oil in the airbox problems?
I have my thoughts on it but there has been reports that:

1.) Removing the felt in the crank breather or
2.) A new Labyrinth plate (was installed wrong or warped)

will fix the problem.

Please give me what you think is causing this issue and what the fix is.

thanks,
Jim

 

This problem just started showing up when I was retiring.Some have exchanged parts from a 2012 model up dated breather vent system,plus there were couple other things people have done,but here's the first bulletin on this.http://www.google.com/url?sa=t&rct=j...,d.b2I&cad=rja

 

Thank you, that is helpfull.
