    I installed a fan shroud on the Head2wind kit, just ordered the same shroud as the other side. It is easy to modify and fits perfectly, it redirects the hot air toward the outside beautifully. Looks pretty factory to me as well. Only cost me about $6 and 15 minutes of my time.

    I haven't had my 990 long enough and in warm enough weather to get fan running much, but it looks like I will need to add a second fan to the growing list of upgrades.

    There are guys using Evans here at the shop that are getting as much as 28 degrees F cooler (digital coolant gauges) which is a lot

    EDIT: I would not recommend Evans Coolants at this point as it is epxenisve (+$40/gallon) and your entire system musty be flushed with it to remove the old coolant. Also leaks past water pump seals & head gaskets on customer bikes. Smells bad. Emergency top-ups can only be with Evans, not water or coolant commonly available

    of course I have the H2W 2nd fan kit & the lower thermostat on my bike really works to keep the temps down, and quickly. Fans go off pretty soon after coming on compared to one fan where it might run for minutes depending on just how hot (& slow-going) things are

    bumped so can find photos with other computer to do install.
    edit: job done, had LHS & RHS tank off so it was easy peasy.

    I'm in the UK and I've just fitted a second fan, an OEM one from another 950. I have had some overheating issues when abroad last year in hot conditions and slow moving traffic in Poland, Austria and Italy. I took the bike into a dealers when in Austria and they reckoned it was an air lock. After raising the front and burping the system; cleaning the rad fins with compressed air the bike still overheated in Italy.

    I'm going to Morocco later on this year and I've incorporated a switch into the fan install so I can flick it on and off as and when required.

    I glued foam to the fan where it would come into contact with the radiator.

    Also used foam and cork type washers for the ties.

    I had to trim a little of the fan shroud as it was interferring with the radiator hose.

    Fan in place.

    Took power source from my new aux fuse box install.

    Put an extra relay in the power source to the fan.

    Switch wired and fitted.

    I just received my rally fan kit from AdvMachines, just wanted to add that Ken is an awesome guy, they did not ship to Singapore and after an email request and a verified PayPal account he was kind enough to add the ability to ship to Singapore. Also the package arrived and they had short shipped the 200F switch, couple of emails later Ken replied to apologise for the overlook and inform that the switch will be sent to me with tracking ASAP.
    The kit is really well made and of top quality, the 4" spal fan unites to the bracket flawlessly and the install is a breeze, less than 15mins.
    Did not have to rig up any special coat hanger tools, with patience as in the instructions you wil be able to line up and clip in the power leads. (or have the wife or kids handy for it, have a light to check if completely clipped in and it's done):D
    I also took the time to add some silicone grease to the terminals of the leads prior to installation for longevity of the electrical connections. (peace of mind against water and corrosion)
    Big thank you to Ken @ AdvMachines for being a top guy and producing such a simple and well made product worth it's weight in gold. Can't wait to receive the switch to complete the setup which hopefully will solve my heat woes on my adv.

    ...or find one of those lucky individuals who work on a drilling rig & beg some detergent off them. The stuff we have cleans out BOP's & mud tanks, so it would have no problem with a grimy coolant reservoir.

    I just installed this kit on my 2012 990 R. It appears to be the ADVMachines kit, but I got it from Craig at CJ Designs because I was ordering some other stuff from him too (what an awesome guy - that Craig!) Getting the splitter connector connected to the the OEM fan connector was a real challenge for me. I used the coat hanger technique because my hands are way to big to get that far in there and no women or children were available at the time of install. When I finally heard the connectors snap together after fumbling about with the homemade coat hanger hooks for about an hour, I bet you could have heard my celebratory scream 3 houses down... "OH YEAH!!!!"
    I did not opt for the lower temp sensor, and I'm glad that I didn't. When the fans do come on, they only stay on for about a minute then then turn back off, which is often enough time to get back moving at speed again. With only one fan, that time was much, much longer and the cooling effect was obviously nowhere near as good.
    This represents the end of a pretty long quest for me to get the bike to run cooler in low-speed situations. I tried new pipes (FMF Q4 Ti), a better flowing rad guard, Engine Ice coolant, burping/bleeding, all to no avail. I wish I'd have done this first.

    I heard it here in the PNW :clap

    Yes, CJracer is reselling the ADVmachines Rally Fan. Yes, reaching across the bike through that small portal is a major PITA, especially when you are doing it with a coat hanger...:puke1

    One of the things that I have found that helps is to pre-seat the fittings with the Rally Fan plug and the new harness before attempting to do it with the mr. gadget fingers (wire hanger). This will help line up the terminals in the plugs.

    Alternatively it may be easier to remove the left side fuel cell, remove all the radiator mount bolts, the 5.2" fan mount bolts (to expose the electrical connector), then install the Y harness connector.

    Once installed, it really makes a major difference (positive) in how well the engine manages it's heat! :freaky

    Or wait till you are doing the valves. Plenty of room then...:D
    I added a reworked shroud to mine to keep the heat out of the right fuel tank.

    Oz, I'd like to see/hear about your reworked shroud. I've been thinking of ways to make that work.

    x2 - Had read about it being done a while back, got the same part # recommended but seems too big for the area. Any help is appreciated!


    Light just flickered a bit...larger OEM fan/shroud vs smaller aftermarket fan so shroud is larger. Guess some "cut and paste" to make it work

    Not sure I took any pix but it was not my idea - check out post 135 here:

    http://www.advrider.com/forums/showthread.php?t=465977&page=14

    Autostream (another Aussie) has some good pix there.

    Not sure how well the OEM shroud will work with a bigger fan, but anything is worth a try. (Smaller fan...cut some off and or bend it to fit). I am allergic to the sound of boiling fuel and have heat taped my airbox and inside tank surfaces as well.
    I know I had to cut mine down some and used a zip tie around the leading edge of it to hold it in place. It took a while and lots of cut zip ties to get it just the right shape to not rub on the tank...much. Not sure how more pix of my install after the fact will help but if I get some garage time tonight I will snap some. PM me an email address if you want them quicker. Like I said its kind of a suck it and see thing and the clearances involved are probably different from one bike to the next. If your not concerned with rubbing off some paint it will probably go easier.

    Well I just bought me an 04 "S" and where I live temps are consistently around 110 degrees so I am figuring that this is gonna be a must do mod. I also use the bike for doing Moto work at Professional cycling events so at times you are going a little slower than you would want to go. I would love to hear more about the fan deflector shield people are using. Is the BDCW fan basically the same as the ADVMachines fan? Also do I need to change out the Thermo with this install? Will it help that much more? I figured just having the dual fans would be enough but I need the most help possible so if changing out the thermo is necessary I will go that route. Lets keep this thread alive. It's crazy hot this summer..

    My opinion fwiw:
    I have the second fan and find they run constantly when under 35 mph on hilly offroad in lower gears...enough to nake me want to go faster when I can. In your temps I don't see the point of staging the fans. A lower temp switch might be a good idea but I would only do it if you find you are still topping out the temp with both fans running. Some report good results using engine ice.
    My big recommendation is applying heat foil tape to the outside of your airbox and inner walls of the tanks. Before my second fan/heat foil I was boiling fuel and cavitating my fuel pump on 100+ deg days. Wouldn't hurt to burp your cooling system if you haven't done it, just to be sure you have no air trapped.
