Don't know the real purpose for that tube, but without that rubber cap it makes a really big vacuum leak and crappy performance! Run down to the auto parts house and pick up some of those little rubber vacuum line caps. Somewhere around the garage, I've got about 100 of those caps, if I could just find the darned things! NOW GO TO BED, OR ELSE SANTA WON'T COME !!View attachment 38423 At the top and left is an open tube... mine has a 'cap' on it but the cap is splitting so I need a new one.... what is it and what does it do.?
Dam I bet, there's no feeling like riding just after the sale and sencing or seeing something is wrong.Yes a extra vacuum line. Those caps dry rot after a while. When I bought my bike it was setting for a while. On the ride home one fell off, bike ran like shit. Lucky I had some black tape and found the leak. Bike ran fine the rest of the way home. Had me scared for a while.
Used to open the butterflies valves on the air intake.WTH is that?![]()

Do they require a backer plate for the super G ?It was a freebee, and the butterfly's move, which is cool. I know it doesn't do any thing for performance.
