Hi
New to this board, just purchased a NC30 fully race prepped for track day use. the coolant expansion bottle has been removed and a plastic overflow bottle (one way) has been added - this mean I have no idea if there is enough coolant in the rad when I look in through the cap.
Anyone got a rule of thumb bit of advise where the coolant should reach if the bike is cold.
Cheers

Top of the rad i always thought, The plastic bottle is just there for overflow.

I just fill my rad up till its just below the overflow pipe, run it and then empty any water from the overflow bottle.
