I've noticed over the years that when I see a bike with to much oil, they always have excessive oil in there air box. Coming from the vent off the top of the valve cover, and oil vapor being drawn in from the vacuum of the motor into the air box. I check the 'bulb' (lower left side of the air box) for oil / water / condensation and that's gives me a good idea. This 'bulb' should be kept clean and checked relatively often for over all general maintenance.WJBertrand said:That's my understanding too Fred. I don't think there's anything we can do to affect the level of oil in the engine, that's dependent on what the pump delivers and how much drips off and accumulates in the crankcase when the engine is shut off or when running how much the scavenge pump returns to the tank (assuming that's how the oil gets from the crank back to the tank?). This is not my first dry sump engine as my old Norton Interstate also had such an engine. Instead of being cast into the crank case though, there was a separate oil tank under the right side of the seat. That bike had a dip stick attached to the oil tank cap to monitor the level. As long as there's adequate oil in the "tank" to feed the lubrication system and enough volume not to overheat/overwork the oil that's there, things should be jolly. I was concerned about over-filling the tank as on my Norton that would cause the oil to overflow when it fully thermally expanded and dump oil, potentially in front of the rear tire. How does the Tenere handle over filling? Does it spill over into the crank case?
Over filling the oil reservoir tends to lead to a lot more oil in the air box in my experience.
