    When I put that part number in at sunset it seems to be coming up as a screw of some sort. Maybe I missed something?

    Based on that part number it is for the screw that holds the butterfly onto the shaft and not the butterfly itself.
    The butterfly is part 901.100.965.00 and I would guess for 40mm carbs so not the 38mm you are looking for.

    Yes, sorry. I put the screw part in. The 40mm was what I was afraid of...

    Why are you afraid? Do you think someone sleeved your carbs down to 38mm?

    I'm assuming you want a 38mm butterfly for your MFI.
    I'd get in touch with Matt from Eurometrix to see if he has an extra throttle plate available for you.
    Warning: After seeing the pics on his website you may be inclined to just package up your entire system and send to him

    I think the 38mm would be for his throttle bodies being a 71S, not carbs.
