I can't believe that, as detailed as PH14 was with the C14 oil change procedure, he forgot one very important step.....
Measuring the oil quantity. I find the best way to accurately meter the oil is to use a syringe. A large 100 ml horse syringe works best, as it minimizes the number of plunger pushes that are required to fill the crankcase. The job can get quite tedious and time consuming with a 5 or 10 ml medical syringe.
You are so right, I left out that important step. I use a different technique though, I set up an IV with a drip count sensor. Either way it's important to be accurate when refilling the engine with oil.
I would also like to add that the sight glass is not a good way to measure the amount of oil in the engine. Once you have filled up the crankcase with oil and measured accurately, you need to weigh the bike. Write down the weight. To check the oil later, weigh the bike again, if it weighs less, add the corresponding weight in oil. The bike must be freshly washed when you weigh it. You may accumulate several ounces of dirt and bugs as you ride and this will throw off the accuracy.
To be even more accurate, since scales are not always perfectly accurate due to the springs involved in many, you coulld use a balance type scale to find the actual mass of the motorcycle, although these would have to be rather large. Another method would be to place the C14 into a large container of water, such as a pool, and calculate the amount of water it displaces. Any way you decided to do it, be sure to do it exactly the same way every time to assure and accurate measurement.
