I'm changing the coolant on my 1986 K100RS. The manual specifies 2.8L in equalizing tank. What in the heck does manual mean with "in equalizing tank"? According to the instructions here, I should poor the 2.8L of mixed coolant (60% distilled water and 40% antifreeze) through the system cap until fluid just starts to come from the filler neck and flow to the overflow tank. I did that, however, the coolant never reached the filler neck. Do I need to poor more than 2.8L or should I just fill the overflow tank to 1/2 and start the engine?
