On the subject of oil, my past bikes, as far back as I remember, had temperature ranges in the owners manual that gave at least a couple of options on oil weights. Usually 10-30 for milder climates or riding conditions, and, say, a 10-40 for higher temperature zones or more severe riding conditions. I don't see anything like that in my owners manual? Did I miss something? I hate to arbitrarily switch weights "just because" if the manual doesn't refer to it. (Just call me overly cautious!)

It shows -----10W-30--------10W-40->
There is no break or any area delineated for the 30/40 crossover, just the 40 weight shown at the end of the scale, near where the temp is 110F.
I take it to mean that during the height of the summer if your ambient temps can be over 90 degF 10W-40 is recommended, all other times 10W-30 is recommended. Since I just bought the bike and this summer has been cooler than normal, I changed the oil and used 10W-30. If we get a week long last hurrah heat wave, am I going to go out change the oil to 10W-40 for a week or two? Nope.
Thanks. What page in the 2014 U.S. owner's manual? My manual only has 3 references to oil and all of them say the same thing, 10w-30 and no other option. No interpretation of weather limits are offered in my manual. Probably a good thing since you must follow the manual to keep the warranty in force. Perhaps there has been an update? Perhaps the 2014 manual IS the update.
