Hey all, as I've stated in previous posts, this is my first wing...a '77 GL1000 so I'm hoping for some experienced insight before I go poking around internally. The bike runs pretty good, I can run all day as long as I stay below 60 mph. As soon as I go over 60 the temp starts to climb. It takes a little under 5 minutes to start but as soon as it does it steadily climbs to the high side of the operating range. The fan is wired to a toggle switch so I turn it on then, the temp stops rising but will not come down until I slow back down below 60. Even if I start the fan then accelerate beyond 60 it still does the same thing...goes to the very high side of the op range then levels out. I've checked the usual suspects...flushed the cooling system, filter & oil change, water flow from the pump seemed fine. I thought maybe these bikes normally run warm but haven't read anything to support this. Any opinions on where to start, I'm all ears.
