What oil do you run in your Raptor ?

 

I use syntetic. Motul 300 V factory line.

 

Castrol 10w40 motorcycle oil, and in the heat of summer 20w50. But whatever oil you use make sure it is rated for use with your clutch. Automotive oils have friction modifiers in them and these will let your clutch slip and eat it up.

 

Yamalube. & what radman said.

 

I'm running Amsoil (synthetic) 0W-40
