Ok guys I have an 09 polaris scrambler 400. Motor was just redone and everything.

Had a coolant pressure issue due to not bleeding the system. That was fixed.

Now when it gets warm if I rev it high revs it kicks out the top of that radiator through the radiator cap. Could this just be a bad cap. It doesn’t do it on regular revs just on high revs that I can see.

Any help would greatly be appreciative
