its not the overflow..
its not water pump or any seal from it..
seem's to leak when i ask power at the bike. (some of to much pressure)
i put some collant in it something like 1/2 over the upper line .. i can ride allmost all day and when i get home its not even Under upper line..
i need help.. i found some picture's on the net from where it THINK it's leaking... any hint ?
the close up picture come from my bike..



thank you all
