So I had the heat issue on my 800 and dealt with it. Until I started to get the "HOT" light lamp on the display. This was occuring in a more consistent basis and cleaning the rad was having less and less of an effect. Fortunately I knew it was the radiator so I went and ordered up a SuperATV rad. Installed it and never had any heat issues again.
Hmm, ok you guys got my attention now. I'm always open to learning new ways to solve a problem. I never had any problems with the engine overheating it was always just the exhaust heat blowing on your leg when the fan was running that was a problem. So you guys are saying if I just cool the engine better with more fan, better radiator etc. that it will stop or significantly reduce the exhaust heat on your right leg blowing out the opening in the side plastic?
If that's the case I might have to rethink my approach to the issue.
For those riding CA the problem was not that they were overheating; instead, CA needed the engine to run at 195 to pass US emissions. Contrary to what the racers felt the hotter engines also performed better.
Most CA riders were also MUDDERS so their rads did not perform like a new one and there is NO
bringing them back. You can hose the rad clean but you will never get that mud film off that acts as installation. The rads in mot cases were working but not as good as they should. I went to a temp controller with a probe and brought the water temp down to 140 as opposed to 195. As I recall CA had the fan come on at 195 and turned off at 180. The engine ran cooler and this helped bring the exhaust temp down some. But the big difference was the water temp that was blowing across your leg was far less. The 140 water temp along with the cool ambiance air temp did the trick.
The interesting part was those ridding in the southern states where the air temps were nearing 100 they wanted to ride wearing shorts which placed the high exhaust temp on there bare leg.
The controller that we used came from most auto part stores. The controllers were being used by the off-road jeepers for the same reason.
CA had an even worst problem. The hight temps were melting the plastic and seats.
After the temp change, I did a lot of performance testing of my bike. I found that the cooler engine delivers more power as opposed to less.
When I first got my 15 850 SP I checked the fan on and off temp. This was easy with the PoPo because the dash has an engine temp readout. I on longer remember the temp but it is far below 190. More like 165 or less for the high side.
