1989 FZR400 Cooling
Posted: Sat May 17, 2025 10:18 pm
Hey all, I finally got my FZR back on the streets. The temp gauge seems to live right under the red but has not gone into it yet. It was a previous track bike so I am wondering if the thermostat was drilled and how to test that? I am under the assumption that the thermostat would test normally if put into boiling water. Much appreciated
