You're not running your oil at the 'Full' mark on the stick are you?
Also, if it's been very hot recently and you've done any slow speed/commuting type riding the engine will suffer higher blow by due to the lowered viscosity of the oil which in turn increases crankcase pressurisation and taxes the condensor system more. That simply means that more oil vapour and particulate matter ends up in the airbox and getting dragged through the stepper.
Just let it find its own level and don't add any more oil unless it drops off. The bottom of the stick. Even then just add enough too bring it up between the marks, not to the full mark.
As you know, here in Oz it gets pretty damn hot in summer. I've yet to see a 1200 pump itself dry, even in the hottest conditions. A common sense approach, rather than rampant oil quantity paranoia, will result in it being far less likely to end up with a grubby stepper and the problems associated with it.
Note that even when the oil is dropping off the stick entirely there is still over 2.5 litres in there, more like 2.75/2.8. That's plenty, it really doesn't get worked particularly hard and no thermostat means that the cooler is always flowing maximum volume and it's the cooling circuit that needs the help most, not the bearings.
