Brian, technically that's correct. Short answer to your question - I fill mine to the bottom of the filler opening. The reason being is when the frames were first produced, there was no concern - legitimate, IMO - about keeping the engine cooled with less oil capacity. I believe the original destination, correct me if I'm incorrect, for the oil filler cap was behind the steering head on the frame. Placing it in front of the seat but off a certain amount of oil capacity. At any rate, the added oil won't blow out seals, etc due to the overflow pipe at the upper portion of the frame. With the summers around here averaging 100F, I like a bit more cooling capacity.

HTH.

After reading my reply, I made an error. Nothing catastrophic. But it should have read, "there was SOME concern...." rather than the incorrect "there was no concern...." about cooling, etc.

I'm tinkering with mine now and the level is about a finger's length below the filler plug/oil access in front of the seat. I know I've got extra oil that was put in the primary to drain over, so no worries on it being lower than what I normally ride at. I'll simply check it after a few minutes of running the engine.

HTH

PS. Yes, you should see the oil returning to the tank via a small hole in the "rod" protruding down from the upper portion of the tank. At even low rpms, the flow of that oil should seem like a steady stream. Just turning the engine over, switch off, one kick, the oil should squirt out fairly coinciding with the compression. ie "phomp, phomp" - two squirts, etc (silly exhaust/compression illustration, I know. smile )

Think you might regret filling to the bottom of the opening.

When it heats up or pumps a bit of oil out of the sump, and you happen to open the cap, you'll end up with the biggest mess imaginable.

You don't need to ask me how I know; just imagine it.

There are high and low marks on the dipstick for a reason.
