1987 EX temperature gauge high and fan not working
I have a bit of a problem with my 1987 EX right now. When I purchased the bike a few months ago, it was not running, the flywheel had thrown a magnet, the carbs were gunked, and it was in need of many other things. After a winter of tinkering, I finally have it running great and all of those problems are resolved (much thanks to these forums!). My problem now is that the temperature gauge reads way too hot after some light riding. The fan does not work either (PO decided to screw up all of the wiring for it so that is a whole other issue), but I wouldn't think it would make a HUGE difference if the fan isn't running on a short ride without any stopping. The bike runs fine, no loss of coolant, it has a fresh coolant flush, and no smoke or indicators of coolant leaks anywhere. I'm pretty stumped with this one. I would like to just wire the fan to be on a switch, as the wiring harness has been tampered with more than I would like, but I'm not really sure how with the '87 model because it has a different temp sensor than the later models. Would this be an issue with the temperature sensors, lack of functioning fan, or is it truly overheating? I have been only taking it for veerry short rides to avoid issues in case it is overheating.
If there is any other information that you need, just ask!
Thanks so much for your help.
