fan kit on a 570?

'Fan kick in' depends upon several factors including the the rating of the fan thermo-sensor, load on engine and air flow through the radiators. The fan will kick in the most when going slow and/or when the engine is laboring. Under most riding conditions the fan may never kick in. It is analogous to electric fans in RVs and autos where the fan kicks in on uphill climbs while the engine is pulling hard.
According to my Trail Tech TTO gauge the fan cuts in at 102 deg C and out at 96 deg. When the fan does cut in, usually when stuck in mud or snow on slow trails etc, it is more than capable of keeping the temp under control and peventing a boil over.
The earlier fan kit had an 85°C thermoswitch which can drain the battery as the fan runs too much.berger said:

I live and ride in one of the nasiest, hottest places on the planet. Still on the original battery (2.5 years old) and never had a dead battery. That's with running a Trailtech X2 HID as well. I would rather have the motor run cooler than hotter.....just sayin....GregUK said:
I have a 2011 FE 570s and have not put a fan kit on it, but that has been the one thing I have been thinking about. I don't think I have ever had it boil over and lost fluid, but I know I have heard boiling that sounded like it was coming from the radiator (although I'll admit that I have now started to question myself on if it was really the radiator or if it was fuel, which I have also read about...). In any case, can any of you help me make up my mind on if this is something that is worth the money or not? Thanks!

It's definitely worth the investment. I put the fan kit on my bike before I even rode it. Sometimes its a little surprising where and when the fan comes on. In some situations it comes on and you would think there was enough air flow, not enough load, but, it comes on.
I've been in other situations, tight technical terrain, using the clutch a lot, and hot ambient conditions, and the fan runs continuously.
I have a 2011 FE570S and had the shop install the fan kit at point of purchace. To the best of my knowledge it's never kicked in, and I'm not a fast rider in the slightest. But if it keeps me from being stranded just once it's a good investment.
2011 FE 570S here too and I installed the kit myself. Just for a test I idled around my block for about 10 minutes and it kicked on so I cooled it down and then shut it off. Since then it's only come on twice that I'm sure of. Once was when coming down a very long hill that some loggers had cut up badly with huge traps and slash piles...I had to idle and peck my way down that hill and the fan kicked in about 3/4 of the way down on an 80 degree day. I say it's worth it but if you're gonna do it, do everything at once so you don't have to take the bike apart multiple times...wrap the header, line the tank, add the subframe tank if you are so inclined, etc.
Thank you Dale, Ruger, and BlueDevil! It sounds like I'll be spending even more money on a fan kit and now based on BlueDevil's comments, I guess I now also have to consider wrapping my header and lining my tank (I already have the subframe tank!). Questions at this point are how difficult is it to mount the fan kit? When you say "line the tank", are you talking about the CV4 tank barrier or something else? Thanks again!

No worries on killing a battery. Shane Cuthbertson ran 2 fans on his bike at Romaniacs and no issues whatsoever. I'm not sure the exact output, but the stator will put out over 200 watts of power, plenty for keeping the battery up to snuff.
Berger...you should move north to a place that is not so hot in the summer lol
