I'm brand new to MBF (like this is my 1st post) and am hoping that I can get some suggestions on why my trike tends to overheat. I seem to be having to top off the radiator every few days now. When I do top off, I am adding premixed antifreeze (green). I don't see any leaks and I'm wondering if I'm boiling it off (bad thermostat or bad head gasket or loose head bolts?)? I don't know where to start and was hoping for some suggestions. It is a zz4, 350ci/385hp motor in an 07 trike. Thanks !
