Quickest way to check is to remove one of the carb tops (#2 is easiest) and then take out the throttle slide and inspect the needle.
If it has SD-129 or SD-130 stamped around the top, it's a standard original needle.
Ivan's needles have 5 different taper angles ground into them, two of which are obvious to the naked eye.
