    i found putting a manual switch on the stock fan to turn fan on at wil,l works good. the trick is to get the fan on sooner rather than more fans.(like as soon as i stop.I hit the switch) i dont know how the thing is wired as my shop did the work. CT gets into the 90s now and then and it works .but theese bikes really need to be moving for the airflow.

    If you want to set up with a second fan, a GSX 1k or 6k fan works best to clear the headers and not strain the fit.

    Follow the advise for manual fan switch to override in hot conditions.

    Install a Honda Accord or similar type code temperature switch to have the fan come on at lower temps. Here is an article that gives good information on that switch and plug-in. Honda fan switch

    Use Muzzy fans in one (or both).

    Finally, run a 50/50 mix of distilled "ONLY" water, 6-8oz. of Redline's Water Wetter (exmpl.) and ethylene glycol (anti-freeze) - Honda Anti-Freeze works best. Mix all in separate container - pour in.

    DO NOT USE PRESTONE DEX-COOL, IT WILL CLOG, COAT AND DESTROY YOUR COOLANT INTERNALS!!


    I would do all above sans the second fan first,,, then re-access operating temps before going with the second fan install.

    Hope that helps. [​IMG]

    I Run a Muzzys Aluminum Fan Blade that they sell for the Hayabusa on my 02' Turbo and Have Never had a problem after I changed it. I believe I got it from Schnitz. Put some Blue Lock-tite on the threads of the Blade screws!:rolleyes2:

    Ok...
    1) Muzzy Aluminum Fan Blade on stock fan
    2) GSXR-1000 Fan (Muzzy makes a fan blade for it also)
    3) "Engine" Ice Fluid
    4) Highpressure Radiator Cap
    5) Manual Fan Switch
    6) Lower temp thermostat

    ...They also sell "fin combs" to comb the radiator fins straight and clean off debris.

    Not sure why you guys need more cooling ?

    Both of my Mk1's had rad guards in front and still never got above normal
    even with heavy use and abuse in Australia's summer, road or Drags.

    I suppose it might be an issue with tuned motors ?

    If its any help Guy's, a B-King also has twin fan's as stock.

    there were some heating issues in the 99-07 busa's, may be that is the reason the 08 busa was launched with two fans

    News to me. Had 2, an new 04 and a 2nd hand 02 (still got)
    Temp doesnt even get high at the drags or in the city.
    Never heard about that. It can get warm in Australia.

    I wonder if the US bikes are set up slightly different ?
    Maybe running leaner and producing more heat ?
    Perhaps there's a slight mapping difference ?
    I know your B-Kings have differnt immission set up's to the rest of the world.

    Not disagreeing with anyone, just find it interesting.

    Overheating happens at idle. So I don't think fuel mapping is the issue.
