Most of us have had overheating problems, usually on really hot days while stuck in traffic. I've run through everything - there's no air in my water lines, I'm using a good mix, etc... there's a reason why the 660 Rally's have dual fans and today I finally picked up a second fan for my 2000 Adventure. Upon first inspection, I notice that it is the NEW fan - the one included on the new LC4s, which is MUCH bigger and it has a big casing to go with it. After I took the tank off and fiddled with it a bit, I noticed that it would take a little casing modification with the knife to get it to fit on the right side radiator because of the decompression cable, but it would easily fit on the left side where the original, smaller fan sits. Now before getting started, I recommend disconnecting the battery, or at least removing the main electrical system fuse next to the battery - this is especially important when handling the Capacitor as if you're not careful, you can short the leads on that thing and... and... well, not much, you'll probably just blow out the main fuse that you should have removed. I first removed the Capacitor and bracket, becasue it was in the way on the right side and the I removed the original fan and remounted it to the right side and put the new one on the left side. No problems so far. New BIG fan on the left side: Now I have this orange colored capacitor dangling there I can't for the life of me figure out where to put it so it doesn't make contact with something else. My solution was to mount it using the front most bolt on the Thremostat. Of course, since I'm certified, I removed the bolt and instantly had coolant shooting all over me. Do the opperation quickly and use a finger to stop the coolant while fumbling to thread the bolt in the Capacitor's bracket. The bracket can face inward (to the engine) or outward (like KTM puts it at the factory). I had to make it face inward to clear the tank. Capacitor attached to the Thermostat(note the coolant that shot all over the place): Now, it looks really nice, but there's only one plug for the fan, and now I have two of them. Easiest solution was to chop the plug off one of the fans (I chopped the old, small version as it has really thin wires) and splice them into the the other fan's wires, just before the plug. I think you gotta get the pos/neg right, but am not sure if it matters. I'm not an electrician. I turned on the ignition on and tested the setup by shorting the thermoswitch in the right side radiator with my screwdriver. Both fans instantly shot to life. Both fans. Looks cool eh?: I put everything back together and went to roast in some Bucharest traffic. No overheating, fans come on, and whats really nice, is how quickly they turn off. Normally if you sit in traffic and crawl for 15 minutes to your destination, and leave the ignition on after parking the bike, you can hear that poor little fan go for 3 minutes or more. Not anymore. The dual fans cool things down really quickly, and I haven't seen them go for more than 10 - 20 sec. after shutting off the engine. I had kind of hoped that having two fans would eliminate the "blowdryer" sound I get when the fan kicks on. No suck luck. Its now "Blowdryer 2: in Stereo!"
