Using the sight glass is tricky. The bike has to be perfectly upright, on level ground. I sat a small level across the gas cap, and had my wife tell me when it was bubble perfect, the first time I did an oil change. Measured how much I put in, and use that as my guide. A couple of degrees lean of the bike in either direction, and the sight glass oil level is completely off. Also, whether you use a long or standard oil filter makes a bit of difference.
Was on a ride with a friend a few months ago, and while stopped for a minute, bikes off, he glances down and tells me that my oil level looks dangerously low, barely showing in the sight glass. I position myself as perfectly as I can, and stand the bike as level as my eyes will allow. "Check now", I say. "Never mind.", is his reply, after he sees the oil a hair below the top fill line.
I also believe that there are only two dangerous extremes when it comes to oil: Way too much, or way too little. Two or three ounces on either side of the perfect amount, is NOT going to result in catastrophic failure. Pick a "round about" amount, and ride the chit out of it.
