Guys, I'm glad this topic came up again, as I recently found something that may be of interest to all of you...
Every oil and filter change I've done, I've put in 4 quarts. Yes, the manual only calls for 3.9 quarts, but everyone here says, "Pour 4 quarts quickly and be done with it," so that's what I've done. At one point, I checked my oil and found that when the engine was hot, the level was above the upper mark on the dipstick, but I didn't think too much of it, because as I said, the advice is to pour 4 quick quarts and call it good. Anyway, I recently replaced my clutch and found the inside of the clutch cover was full of oily foam. This tells me one of two things: Either there's water in my crankcase, which I don't feel is the case, or 2) The crankshaft is whipping the oil into a froth. The reason for that would be too much oil in the crankcase. After I installed my new clutch and put everything back together, I used a Ratio Rite and filled the crankcase with 120 oz. (3.75 qts.) of oil. I then ran the bike to see if there were any leaks coming from the new filter or around the drain bolts and took 'er for a blast. When I got home, I let 'er sit for 5 minutes or so, then had "the wife" hold the bike upright while I checked the oil level. I then added oil to bring the hot level right to the bottom edge of the top-most mark on the dipstick. Since then I've put more than 500 miles on the bike and have had absolutely zero problems. From now on, I'm putting in just enough oil to hit the upper mark of the dipstick when the engine is hot -- no more, no less. IMO, you should be filling your crankcase with just enough oil to hit that mark when the engine is hot and the oil's had a chance to settle back to the bottom of the case. And remember, whether the engine's hot or cold, as long as the oil comes between the upper and lower marks on the dipstick, you're operating with a safe amount of oil.
