Checking oil level: the finer points of dipping

Hi,

I did an oil change yesterday and put in 1.8L oil after thoroughly removing the existing oil that was in the bike for about 2.5 years. I hadn't used the bike so I changed it and am ready to fire it up with the new battery. When i removed the old oil, i opened up the front and back drain plugs and the oil filter plug to replace the oil filter - so I think I drained everything out, unless the cold oil didn't leave fully because it moves real slow?

However, when i checked the new oil level, it was way above the max mark. I measured it cold, upright bike, and didn't screw in the cap. I know I am supposed to measure it after running the bike, but I don't want to start it without knowing what the right level is.

How should I start the bike now?
1. drain out the excess oil until I go below the max on upright bike?
2. start the bike as is and see what happens?
3. a smarter option ?

Really appreciate the response.

Also, does any one have a link to owners manual ? v7 2012 racer.

Best,

I've found that Todd's recommendation of 1.6L is spot on for my bike: slightly over the min mark. Mine's a 2016 though...

I've been trying to wrap my head around the operation of the V85 "partial dry sump". My assumption is that while the bike is running, oil is scavenged from the sump, causing it to basically be "dry", but when the motor is stopped, oil is allowed to drain back into the sump, making it appear "wet" (and allowing the sight glass to actually be able to check the oil. If that were the case, then I would assume that a hot engine would need to sit for some amount of time to allow the oil to drain back to the sump... but, the owner's manual doesn't state that. Anyone familiar enough with the internals of these new motors that can help edify us?

Yes... the crankshaft and base of the crankcase (oil pan) is completely isolated (separated), unlike the big block motor whereas the oil returns to the pan via the block and passageways via gravity.

Thanks! Yeah, the older big blocks definitely had some issues with oil-handling, hence the desire for lots of folks to add windage plates, or (in my case) the aftermarket deep-V sump. My assumption is that the new design eliminates all that b.s., and could be why they redesigned the oil system in the first place. I've been able to suss out a bit of it based on parts diagrams and some photos of the case that I've found online, but the engineering mind in me would love to see a detailed diagram of the various oilways and galleys... just to satisfy my curiosity. For now, I'll just trust that it works :)

You won't get an accurate read until you start the engine and let the new oil filter fill up.
