Haha i knew an oil question would bring up a few posts.
Randy where does your oil sit when cold and not running? Im happy to go with what the team of the year does.
Honestly I do not know, I never look at it with the engine off.
The level of the oil when the engine is turned off is going to be different based on the coolers you have and how they are plumb. For instance, the coolers I use on my Legends cars fully drain back into the crank case when not running, while the layout for the roadsters only allows the cooler to drain about halfway down.
Yamaha recommend the level of oil be between the two lines when turned off & cold. The oil cooler on the bike drains back into the crankcase when not running so that adds to the sump level.
I have found that if you keep the oil below the clutch basket when running, you have less aeration, the oil temps stay down, and you will not push a lot of oil through the breather system. Plus, that means the sump is going to be overfull when the engine is turned off and the oil has drained back.
