    Another thread from the dead, but this one is still twitching.

    Does anyone know what the cfm is for the stock VFR fan? I'm looking at a Spal fan, which is 311cfm/530 m3/hr (for the rest of the planet) and it's thin and lightweight, plus, it pushes, not pulls. I'm wondering if that may help increase airflow over the stock fan. They also make fans that pull.

    I'm also looking at a larger oil cooler from the RC51.

    At the risk of stating the obvious, what is wrong with the standard fan. It works, its available everywhere, & pretty much all 2 rad versions use the same one. These bikes run hot. That's not an issue in itself as look how many are still running 20-30 years later. Personally I think going for an oil cooler may prove to have better results.

    If you go with a pusher fan set up, you are going to want to run some custom shrouds or cooling at stand still will not be optimal.

    Personally putting a piece of gaffer tape over the temperature display may lead the best results :D

    I saw a significant reduction in temps at low speeds, especially on hot days. Otherwise, yeah I would have left it alone.

    As opposed to the 2005 I used to own, the fan on my 99 does not reduce the temperature of my coolant. I've stopped at stoplights and watched it cook at 233°f, never dropping. My 05 would. Ergo, my requests for information. I am running distilled water and Water Wetter and there is no difference between it and antifreeze, except the temps may drop a bit faster once underway. As is the usual, if I'm in traffic or at slow speeds the fan fights the air coming into the front, creating a thermal wall that increases the temp too, thus my curiosity of buying a pusher fan. Ideally, one on each side, but we all know real estate in the right side is precious.

    Thats fine however its NOT COOKING at 233 !!. Thats is well in the range of 'normal to hot.
    Maybe an oil cooler might help you better..
    I've seen 236 & thought phew - time to get moving...lol but we lane split here & stop light GP's & gridlock kinda explains getting warm - lol...

    I put two fans on the outside of the right rad this last weekend. With air dam, these things work as advertised. Phx stop/go traffic is no match for fans on both rads. I have the vtr mod and it ate a rad one day when a rock was caught between the blade and the rad. Bad day for the rad. The left fan now has chicken wire over it.

    I thinks that is the best option, and the upgraded oil cooler for the 5th gen.
    I have a 6th gen right rad which is 8% larger, easy enough to fit but still has the same problem in traffic.
    Most of the time I just ignore it, well sort off, I keep an eye on it as I also have the override switch, in traffic when it gets to 95*C I start the fan.
    This seems to stop it from running away.
    But from my gut feel, I think we might be better off getting a larger oil cooler, a 4 row would be ideal, but you don't want to over do it as cold oil is not a great thing to have.

    If there is an easy fix for larger oil cooler, that would be great.
