Hey my raptor 700 when riding it’s fine but at some point coolant reservoir goes all the way to full mark then when I ride it goes back to normal just wondering is this normal? Seems to be sucking in and out of reservoir to radiator back-and-forth

Normal. Gets hot, coolant expands and needs somewhere to go (reservoir) then cools off and creates a vacuum pulling coolant back into radiator
