I was riding yesterday on my newly purchased 2000 KDX220 which has a temp light from a sensor on the left radiator.
After riding hard for about half an hour, low speed, with power in sand, mud and jumps, the temp light came on.
A little coolant drained from the overflow drain hose. After about 20 minutes, I started and road home with no problems. Has anyone else experienced this?
Make sure the rads are clean through the fins. You can blow them through with a air line.Its suprising how much can build up around the fins restricting the air flow.
I purchased one computer fan with the highest amperage available, got the next one from a trashed iMac computer. Both are 4 inch sizes. Black wire goes to ground. I sent the other wire to the high beam light, so that I would always know when they are switched on. I put the fans on the rear side of the left radiator. Test to make sure they are pulling the air through the radiator. Have not had a boil over since. I have had them on over a year.
:bang: :coocoo:
We don't even have 220's here. Don't take my word for it then, do a search and see for yourself that it IS a common problem with 220's. :whoa: :blah:
