I’ll be liquid cooling the controller and the motor, and rather than trying to reinvent the wheel here, I figured I’d take a look at the stock system and see if it might measure up. Funny thing. I went all looking around the internet for photos or videos, and suddenly it occurred to me I had the frikkin manual. Yeah, I know. I blame the DayQuil.
The radiator tucks nicely up and under the front fairing and it seems pretty big – it should be more than enough. Not only that, I get the filler cap and the reserve tank, which is slick but maybe not needed since I’m not going to be making coolant go to that kind of temps, and I also get the radiator fan sensing and relay electronics. I’m thinking we’re just going to run it as always on, (if memory serves that’s what the bikes I’ve ridden do – once you turn them on you hear the pumps running) but I’m honestly not even sure I’m going to need a fan at all. That will be easy to determine once everything’s in place and tested.
So, with the addition of a small 12V fluid pump I’m good to go, and that can be mounted almost anywhere. Maybe this:
