Yes that is them. The older we get get the dumber we are. You youngins forget. http://www.factorypro.com/prod_pages/prody85.html
The needle runs in these tubse on there way to the main jet. Because of the angle of the dangle the tube wear out or at least become oval instead of round and the bike runs rich. Factory pro tubes will prolong the need to change them out. I had their kit and found that they were hard to tune and the hard needles ovaled out the jets quickly. Their tubes are great with the stock needles and lasted a long time, easy to tune and gave greate midrange.
