Self Filling Oil?
« on: April 30, 2011, 08:42:56 PM »
When I met Chumma I asked him about the problems some people had with overfilling the crankcase oil. He has been inside many RE engines. He said that there is about 6-8 oz that does not drain when you pull the drain plug. It remains trapped inside the engine. Then when you put in the "correct" amount, half way up the sight glass, everything looks OK. When you start the engine, that that trapped oil joins what you just put in. Now your engine is overfilled. Soon your air cleaner box will be filled. I start with 1.5 quarts, run the engine for a bit and check the level. Adjust as necessary. When I expressed my concern about keeping some dirty oil with my nice clean stuff he said it was not enough to matter.

Many bikes have issues like this, sometimes it's an odd galley that hold oil, sometimes the oil cooler.  Don't worry, replacing most of the oil is just fine.  Besides, we're doing this every 2000 miles.  How bad can it get?

Chumma said don't worry. I'm good with that.

in the parts manual, they show the primary case drain and filler plugs and orings like the
Triumph twins do. (vintage).
the mothership has us tilt the bikes on the centerstand left and right
to get as much old oil out as possible.
sounds good to me.

I measure what comes out and replace with the same amount, plus a tiny bit more.

I second all mentioned above, only to add that overfilling may become very dangerous. The position of the outflow in the filter box makes sure that your rear tire will be lubricated quite well. Especially the tire´s right flank will be exposed to the sputter and due to centrifugal force the oil is pressed into the treat. Not necessary to describe what that will do to you in narrow right bends.
One way to bring down this risk is to attach a plastic hose at the outflow in order to prolong it and send the possible outflow anywhere safe.

I finally eliminated the airbox out flow feather.

I ran a hose to the drive chain with a duck bill on the end.
