When people ask about things they can do to make their scooters run better/make more power, I always try to mention jug cooling fans. But I don't see a lot of them make it onto scooters. I see a lot of oil cooler fans, but not jug coolers.
So here's a little example of what cooling fans can do for your engine. I was working on an issue with my fuel system and needed to get some heat in the motor, so I had the fans off. When I was done, I decided to see how fast the temps would come down, just for my info.
Here it is with the motor at 302f after I got done verifying what I was fixing. Its 2:52 on the screen clock. The temp is shown in the second box from the left on the bottom of the active window. Then I switched the fans on.
Then another shot at 2:57 with the motor still at idle. It's pulled down 70 degrees in 5 min, with the motor running. And it was about 60f in the shop. I knew they worked pretty good, it idles at about 180-185f in traffic. And I knew they ran for five minutes or so after shutting the motor off in the summer time. But I had never looked to see how fast they actually cooled the motor down.
These little fans don't look like much, but they will really bring down the temperatures. Way more effective than oil cooler fans. They make a world of difference on a hot day.
So youens what are looking for ideas about winter upgrades, now you can think about adding a set of fans.
