    Interesting.

    I wonder what the cost would be? Probably outside the norm for motorcycle enthusiasts, but no big deal to aviation.

    The only concern I would have is that if the engine is running hot for whatever reason - with water it boils and you know you have problem (albiet a problem that could leave you stranded!) hopefully before any permanent/actual damage is done, but with fluids that don't boil (or have very high boiling points) you could be overheating without knowing it and damage the engine.

    I just acquired a second fan, spliced it right into the first fan's plug, and zip-tied it to the radiator. Been running it for 1000km now, 50% of the off-road. All in about 30 deg C heat. I actually found I was getting to 5 bars earlier than before, and staying there, even once I was up and running at a good 60 kph :huh Fans were coming off and on quite frequently.

    I figured that when the second fan was off, it was actually impeding the airflow where it used to just go straight through once you go moving. When it heated enough, the fans kicked it, cooled it just below the threshold (which is still in 5 bar territory), then turned off again, blocking the airflow. So it just kept bouncing around the 'low' 5 bar mark.

    Of course, I just noticed a fair part of my grill was packed with mud....that probably didn't help.

    I installed the BDCW kit. Had never removed tanks before, so it was an educational experience. The instructions recommend removing the left hand tank as well as right. I reckon you need to do that to get access - I also loosened the radiator to access the wiring.
    Be careful to ensure the screw on the oil breather is replaced square to avoid stripping the thread like I did - had to helicoil it. On reflection, perhaps I should have slotted the fan tab slightly to take the slight pressure of the screw.. 20-20 hindsight!

    Goosefeather,
    Which year bike were you installing that fan on? I'm working on mine now (2013 baja) and have run into a problem with the female wiring connectors and the installation of the allen screw that holds the beather cap down. I almost stripped the threads out and was bashing up the radiator fins trying to get the unit installed. I stopped and called Kurt at BDCW's for help. He sent me a new bracket and wiring harness where I'm still having problems.

    I tweaked the first bracket to get the lower portion to line up with no luck. The new one I was sent had a slightly different bend to it so I though I was scott free, but no luck. Turns out, I still am waiting with Kurt to call me back to confirm, the fan was positioned in such a way that the lower bracket couldn't be pushed in just a bit more to properlly line up the allen bolt and fit over the breather hose. Also the bracket holding the breather hose has to be modified to fit this fan. At least this is what I have found in my case. If you elongate both holes on the breather hold down bracket, it will help prevent inserting the bolt at the incorrect angle. Probably the use of an allen wrench with the angled end will help install the allen screw with some ease.

    The instructions for this install should have some more pictures and it should include the following
    Step 1 - Remove both gas tanks
    Step 2 - After removal of gas tanks, Stop and make a rum&coke, continue fan install tomorrow. :1drink
