Hello I am now concerned after reading something on here . I always keep a eye on my fluid levels so I notice any changes .

From cold my coolant in the overflow has gone over the upper level line . Before it was perfectly in the middle of the upper and lower and was like this for ages
when I run my bike up to when the fans come I see some bubbles in the tank.

I did drop the bike on me drive so I was thinking maybe it took in some air . But I’ve had it running for ages with the fan on and the level doesn’t seem to go back to where it was before . Also once it’s cooled back down the level hardly drops.
The bike runs absolutely fine doesn’t overheat or anything. I read a post on here someone has exactly the same issues and he said that the head gasket was leaking . Can anyone help please?

I would always start with a brand new Kawasaki OEM Radiator cap. A bad cap can cause a lot of problems.

What is the colour of the coolant.

Let's start there first.

what coolant are u using?
premix or self mixed? what ratio?

how old is the coolant? age and mileage if possible

is the coolant in the radiator clear? any oil-like residues?
what about the color of engine oil through the sight glass? any signs of coolant mixed into the oil?

Don't worry about it.

It was just air in the system it sorted itself out to the original level
