    There is a long copper tube on the end to get in front of the collector to avoid having air leaks corrupt your measurements.

    You can make the tube to stick up any of the individual down pipes if you wish, but generally there is no need for different jetting across the carb bank.Having said that the stock 1150's run 1 size up on the main on the inner cylinders. On my 1166 I don't. I used a thermocouple to see if there were differences between exhaust temps which I saw no need for further individual cylinder monitoring.

      You can probe up the exhaust but on some exhausts the opening is too small to fit the sensor through. Probably not an issue with an open exhaust though. In some cases the sensor's internal heater will not get them up to operating temps if too far down stream. Not always, but in some cases. Just depends on what sensor is being used, what controller is used and what condition the sensor is in.

      Best to get the WB O2 sensor as close to the collector as possible. Most say about 30" from the head is ideal. I've tuned a fair number of turbo engines with the O2 bung inserted directly into the turbo down pipe.

      1982 GS850GLZ (Daily rider when the weather is crap)

      Darn, with so many daily riders it's hard to decide which one to jump on next.;)

        Yea I was assuming a straight through design. Most seem to be. I has about 30" of copper rubbing running in fount of the collector. The sensor is outside of the can.

            Try visual cues. That's why you have eyes...

              You could very well be right, Don. I noticed that the OP's last activity was the same time the message was posted.

                  On closer look we may have been had. Maybe I'm a little crazy but 8700 miles in 33 years is just over 260 miles a year. It would still be on first set of tires and brakes. Maybe I'm a little cheap (or poor) but thinking if I laid down cash for a new vehicle I would use it or sell it... Not let it sit around not being used till it's a history piece barely of the lot.

                    or maybe after five or six posts of people basically telling him he is an idiot, he just didn't bother coming back.

                      Weapon, I appreciate that you want new members to feel welcomed; we all do. However when a poster comes out and says they want to run straight pipes on the street (most obnoxious thing next to street stunting you can do) and try to justify it in the name of safety, then take what sounds like an extremely unworkable situation and try to make it work (open pipes, pods, random jets) and have others troubleshoot it won't go positively. You might as well retrofit a screen door on a submarine and ask others to help stop the leaks.

                          I understand and agree that its easy to become exasperated with some of the questions people post on the internet. I do myself at times become annoyed with what I perceive as a stupid question or post.

                          I have been on the site quite a lot lately due to having started a large overhaul on my GS (large to me). So I have been pouring over a lot of question threads lately farming info for my own use. During that time I have noticed some reactions to new users that I felt weren't deserved, or were over the top.

                          No specific users were consistently responsible it just felt like a general feeling of impatience towards some of the new guys. So please don't take this particular thread as the poster child for what I am talking about.

                            It is a two way street, but you are correct sometimes the old timers let their hair down a little too far self included
