When you do your first oil change, I recommend to keep any crumbs from the oil filter cavity from flowing down the 6:00 Clean oil port in the mouth of the filter cavity, (I use a vinyl nipple from a wet cell battery to temporarily plug that hole.) as I tilt the bike from side stand to RH side, three or four times to thoroughly drain the filter cavity and the L & R engine covers.
Then insert the center pipe from old filter thru new filter and re-install into cavity. Install drain plug with gasket.
Find a way to hold the bike as near perfectly vertical as possible. Add ONLY 2 Quarts of your preferred JASO MA graded oil. Note the oil level. Start the bike and allow to run a minute. Turn it off for 2 - 5 minutes to allow oil to drain out of cylinder head.
Now put a small scribe line at that oil level. This is the .5 quart LOW mark with a FILLED oil filter. Now add that additional .5 quart to your engine. The oil level will usually Completely fill the window, possibly even slightly over. Perfect!
The marking on the engine calls for 2.5 liters, which is a little more yet.
Most people do not realize that the KLR engines can re-drain the oil filter overnight or fairly quickly if fully hot oil and parked 'just-so'. Makes for very confusing oil level discussions.
Oh, and the fresh oil will look "frothy", because its aerated. The tiny air bubbles dissipate quicker from Hot oil.
Modify at "YOUR OWN RISK"!
