Was checking out the service manual and noticed something odd in the section that covers Throttle Body Disassembly (4-60). The last step says "Remove the air jets" and the accompanying photo shows the vacuum ports on one of the throttle bodies, with removable jets. I checked my paper manual which I purchased at the same time I bought my 99 Busa and it shows the same thing and attempting to attach the picture.
My vacuum ports do have a restriction inside, which I narrowed down to .038" using a set of micro drill bits, but they are definitely not removable. Not that this is a big deal but was curious and wondered if anyone had any more knowledge on this. Thanks.
