    throttle body size

    I am looking to make my own intake for this spring. I do not know what the throttle body size is to get a coupler and was wondering if anyone knows what it is. My ski is in storage at the moment and I can't get to it to take any measurements.

    Thanks in advance,

    Jeff

    I think it's a 2" OD.
    I'm pretty sure that my R&D intake kit came with a 2" to 2 1/2" silicone coupler to accept the 2 1/2" aluminium intake pipe and filter. I may be wrong and I can't get to my spark because it's buried in the snow too !!!

    I couldn't remember if it was just 2 inches or something weird like 2 3/8. I am getting all the spring projects lined up so they can get hammered out quickly. thanks for the replies. I do plan on using 2 1/2 inch pipe and filter though

    Dell'Orto 46mm with iTC

    I have seen the guys that are putting the spark motors in stand-ups are using the 58mm RXPX throttle.

    Anyone thinking of fitting the 2009+ Bosch throttle body.
    It won't work unless you get crafty.

    The throttle PS and actuator are reversed.

    The plug us straight plug in though.
