    I was looking for a smaller diameter one (aprox 4.5") in order to make fitment easier, but this is what Ryan Watnem at Universal Parts answer to my inquiry

    So I guess, I'll just go and order that one, after all RCruiser already showed us it can fit in there :thumb

    There is aluminum sheet that works good but notice how thick it is. Never work with stock airbox in there.

    Those are his carb synch tubes coming from the throttle bodies to a home-made synchronizer.
    I wish someone would show me exactly where to hook my Twinmaster up...:huh

    Looks like he's synching his carbs. I'd guess they run to his manometer (on the yard stick). Two tubes filled with fluid- one connected to each carb, and engine vacuum moves the fluid. Cheaper than the store-bought units, and probably just as accurate.

    If anybody is interested I found a SPAL 4" fan:

    VA32-A101-62A Fan 4" (pull) SPAL Part # 30103018


    I ordered it instead of the 5.5" because I reasoned that besides being easier to fit, the smaller diameter fan would restrict less airflow when the fan is not turned on (thus requiring less "fan work") am I making any sense ?

    Oh well, it's on it's way, so that's what my bike will have.

    Made the cover on top(not in the picture) and it's still down 2hp from my other airbox. Haven't had a chance to go back to the dyno. Want to try and see if I can get it to help in the mid range some.

    Which mounting straps or brackets did you order?
    Not sure how this works...

    Do you just tap into the existing fan's wires?

    :huh
    I ordered these ones from the same place I bought the fan (A1 Electric) and these ones from Universal Parts Inc which I reckon are similar to the ones used by Pyndon.

    Note that A1 Electric had some pin-style mounts (metal) that looked easier to install just by threading them through the radiator core, but when you go to SPAL's web site they say that the system is sure to cause problems in the long run by rubbing on the radiator (and it's a SPAL product :huh)

    I'm not sure which is gonna work, but since I can't get any brackets here at home, I just took a wild guess. If none of them work, I'll just fabricate some kind of metal bracket, it's not too complicated. The fan is very light.

    Yes, I plan to tap into the existing fan's wires so that they both turn on/off at the same time

    O.K., ordered from A-1 Electric:
    30103018 Spal 4" Fan (pull) $59.95
    30130011 Fan mounting brackets & Straps (4) $16.96

    That said, what's the correct thermocouple to order to kick the fan on sooner?
    Where do yuo find one?

    Those are not the same. I opted out of the spike type because they say they definitely wear on the radiator after a while.
    I got these...

    I thought about putting some heatshrink on the spikes to avoid abrasion.

    Your thoughts?

    Prolly work, but maybe not forever. Radiators are made of soft metal, I'm surprised they actually offer that kind of mount.
