fluid level in radiator

Hey everybody - got a question about the water level in my radiator. I'm using a stock radiator setup, and stock water pump. When the bike is completely cold, there is no fluid above the cores. If i run the bike until it is warmed up(more than just a few minutes) then I check the level, fluid looks normal. Has anyone else noticed this?


Your fluid level should be within 1/4" from the bottom of the filler opening. The reason your lever gets above the core is that after it heats up the coolant expands.
