What needs to be done to safely go to premix on an '06 900 RMK, I know there's two center seals for the water pump/oil injection shaft so I guess a guy can just keep that cavity topped off with oil via the line that use to go three quarters of the way up the oil injection resevoir but what about the rest of the mains with no journals on the upper case half will the premix get delivered out to the outboard mains especially the outer PTO as that bearing is a good distance outboard of the crank chamber. Any input from guys that have done this would be greatly appreciated?
