So I figured today that I would flush out the coolant system and put new in cause I noticed a little white buildup in the reservoir. I opened up the caps and undid the drain by the water pump and drained it out and reservoir and then then took water and poured it in the cap let it drain out then put the drain plug back in. And like I do with my oil i measure it out before I put it in. The manual says it holds 1.6L but when I started filling I got to about 1L and it was full. I started it up and warmed it up and it still stayed full. Anybody else come across this or should I not worry about it.

 

Don't worry about it. Check after your next ride.
