- I just did this with my R6. The simplest method is to pour the oil out into a graduated cylinder. In doing so you can measure the amount that came out, and then pour in the same amount. My "graduated cylinder" consisted of a water bottle I had cut the top off. The ribs on the bottle made for nice reference points.
I used Maxima 5wt oil for my R6, as this is apparently pretty close to the oil used by Yamaha from the factory.
This method may be the simplest but it likely won't yield the kind of precision you want with regards to your oil level. Oil level is a tuning parameter and small changes in it can yield huge differences in suspension performance - small differences between fork legs can be really bad for damping performance. Use a proper oil level tool (such as the Motion Pro) to measure the distance between the top of the compressed tube and the top of the oil, as per shop manual. I believe 5wt is what comes from factory.
Stuff you probably already know - when removing and reinstalling your forks, pay close attention to the
order in which fasteners are removed and installed, as well as their torque values - especially for your pinch bolts and the cap. When it's all back together, undo the right side pinch bolts and pump the forks a couple of times to ensure the forks aren't binding.
