Title: Quick question about midpipe Post by: aa4111 on May 16, 2008, 10:14:20 PM This is a spark midpipe from desmoworld. Is the bung pictured for an o2 sensor or a regular port that is plugged except when being tested/tuned at the dealer??? In other words, is this the for an S2R800 or S2R1000?

If there are two of them, they are small in diameter and are before the crossover , they are for an exhaust analyzer.

Talk to Chris at Desmoworks. I've also ordered a set of black stainless cans so i can route the headers one on either side of the bike just under the seat - i want to see the rear tyre sitting there with the unilateral swing arm. Both should arrive in the next week or so - i'll post a pic when they're fitted.

I do not have the pipes in front of me and wont for a bit so I couldnt inspect in person. You can just barely see the tip of the horizontal cylinder gas analyzer port in the long section of the midpipe. The vertical cylinder port is on a short piece of pipe that you retain from your stock pipes. So it appears I wont lose anything if I just plug that hole... as long as everything still fits the same... which it will... I think.... Thanks for the help everyone
