FE570 with a reservoir tank, different rad cap?
My 570 came with a 1.8 cap. Not sure what the stock should be. It occasionally boils in hot single tracks.
I made a simple reservoir/expantion system. It fills up the expansion tank when hot but never pulls it back in the rads when it cools down.
Question is that should I be using a lower pressure cap like 1.4?
And are all KTM caps the same except the pressure rating? The reason im asking is thay someone posted something about an extra vacuum valve in the centre some cap that allows coolant go back in ,but I can't confirm if my 1.8 cap has that or not. They all look the same!
