Did you consider doing the PCV Valve mod? I heard it reduces oil loss big-time. I did this mod but can't really say if it is working or not being I have so few miles on my bike so far. Mine is a 2012 with about 1,200 miles on it so far. I just got the bike about a year and a half back I didn't ride much due to winter and surgery on my foot right where the gear-shifter sits on my foot. Anyways, I did the mod because I heard these bikes eat oil and I didn't want it to so I did the mod. I have not had to add any oil so far. If you do it, don't use the metal PCV valve, find the plastic one with a Mercedes Benz part number. It has a reed in it than is much faster. If your interested, I'll look up the part number and post it but until then look up the PCV mod and let me know your thoughts about it.
Thank you, for your well-intentioned suggestion, James1967! And . . . nothing to put you down, but . . . thanks for the, "source of innocent merriment" your post provides!
I'm reminded of the opening credits to the TV show, "Fantasy Island" (q.v. on Google, for video) where a little man in a white suit on a tower cried out words to the effect: "Look boss! Da plane! Da plane!" (An indication of the arrival of one or more fantasy-driven guests.)

Some OPINION (vs. FACT) follows:
As to the Mercedes-Benz part, in contrast to the garden-variety automotive PCV valve . . . the upgraded part permits accomplishment of a meaningless act (PCV valve mod) with more efficiency! (Just as a footnote; a typical automotive PCV valve modulates its orifice size inversely with vacuum, I think--the hole gets smaller as vacuum (negative pressure differential) increases; the Mercedes-Benz part, I think, responds without modulation.)
This skepticism aside, if you're convinced your oil consumption is reduced by installing a check-valve in the crankcase vent line . . . more power to you! I await quantifiable tangible indication of the phenomenon (lower oil consumption with the PCV mod), but . . . haven't encountered any, yet.
CAUTION: Likely irrelevant anecdote follows; avert your eyes, if offended by same!
First, I respect Normk's knowledge and experience. Not that we had no disagreements. One, pertinent to the subject of PCV valves: I asserted, one function of a PCV VALVE
on a PCV system-equipped engine is: preventing a flame front from an intake backfire from entering the sump, where flammable hydrocarbons and aerosols might threaten an explosion over-pressure in the crankcase. Normk said he never heard of such a thing, and thus rejected the concept entirely.
Some Google-fu disclosed conventional wisdom corroborating my postulation; I shared the information in a post; heard no more from Normk on the specific and limited subject.
As to crankcase explosion . . . had a 1962 Dodge 318-equipped convertible (Louisiana version, NOT under California regulations at the time); Hard time starting on a rainy, rainy day; much starter grinding, then . . . BOOM! A crankcase explosion drove the oil filler cap/breather from a valve cover into the hood, from underneath, leaving a small convex (from the outside) dent in the hood. Fortunately, no seals were blown by the over-pressure consequent to the explosion; only slight cosmetic damage its consequence.
Now, this story only illustrates crankcase explosion; NOT a confirmation of a PCV valve preventing one (car had only a dump tube; no PCV system). Just sayin', crankcase explosions CAN happen, your car's PCV valve prevents such an occurrence from an intake backfire.
CONTEXT: A check-valve in a KLR's crankcase vent line does NOT comprise a PCV system.
