Rotary Valve Shaft Oil Resivour

[lv2plyguitar 172]

Is there any recommendation on changing the Rotary Valve oil?  If so how often.

 

Thanks

I'm changing mine once a year during my condition inspection.

the maintenance schedule in the book is every 100 hrs.

I premix with castrol.  Should I use something different in the rotary housing.

no, the recomended oil is what you running.... Joe Greheck says to use gear oil in there but everyone else just runs the same 2 stroke that your burning in the engine.  Rotax says to use the same 2 stroke oil also.
