Good advice in this thread. I posted the thread about the fluid change for my Qlink. It's here;

By now, you probably already know how much oil is needed. Please post this so others with your style of bike can have this information as a manual has yet to show up. Both forks need to have the same amount of oil in them.

998S is correct, 20W is too heavy. Go to 10W or 15W.
