Fill it to the top line (bike standing straight up) after oil draining & filter changing (Don't loose the drain plug gasket & don't throw away the oil filter by-pass valve.).
Start it to fill the filter, let run about 1 minute. Turn it off for about 5 minutes to allow the engine oil to drain from the cylinder head. Re-fill to the top line, just a tiny bubble.
Then you can tell me how much you used.
Most people do not understand that the high mounted oil filter on the KLR engines WILL drain back into the crankcase, when parked long enough. Modern Automotive engines will NOT drain back the oil filter.
Personally, I use 2.5 qts.
Modify at "YOUR OWN RISK"!
