    1100E Jetting start point- single cone fiter and 4:1 pipe

    Hey all,
    Just got my bike back to a ridable state, 1983 1100E, now with single cone filter in place of the stock aibox and Yoshimura 4 into 1 and am looking for a little jetting advice. At least a starting point.
    Anyone else running someting close to this setup that can take some of the trial and error out of my jetting hunt? I donot think that my air filter setup flows as pod, but I am reasonably sure it flows better than stock.

    Also, how much do I have to worry about damaging my bike with around town riding, reasonably moderate riding before I get the jetting straghtened out?



    Thanks,
    Derrick

    same set up

    Hello, I have an 82gs 1100e with a V&H 4 into 1, single cone with alter airbox. the mains are 115, and the pilots are 45, I am cleaning the carbs, I purchase the bike recently and do not know if the jets are correct, but I am also looking for help.

      YOU DO NOT WANT TO RUN THE BIKE UNDER LEAN CONDTIONS< BAD THINGS CAN HAPPEN. holes melted in pistons, over heating. to name some. i would try to get the jetting sorted out but any legth of rideing is to be done. maybe you can get a dynojet kit and use there stg 1 setting. look at motorcyclecarbs.com for jetting tips

        If your intake set up increases the intake significantly, you'll have to re-jet all three jetting circuits. Main (3/4 throttle and over), needle (just above closed throttle to 3/4 - test at 1/3 throttle), and pilot (idle and overlap effect with needle up to 1/5 throttle - test at 30/40 mph in higher gears - just cruising).
        Test your bike at these throttle positions and check performance and plug reads. Do what the plugs say.
        And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
        Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!

          A single big pod after the plenum chamber will flow plenty! You have to remember that the cylinders take air in succession not all four at once, I bet you can use a Stage III kit and be pretty close with the recommended settings.

            Derrick,

            I have a single K&N filter and Kerker 4-1 pipe on my 82 1100E. I do not have all of the particulars on the set up (yet, anyways), as I bought the bike this way and the work was done by a local shop for the PO. I have a dyno chart that has a note saying the mains are 132's. So you should likely be in that ball park. I live at 3400ft, which may factor in if you live at seal level, but at least this is a point of reference. As others have noted, you do not want to run it lean. Rich is OK, but lean can cause significant damage if things go wrong.

              Ok,
              Broke down and ordered a Dynojet kit, lot of money for a few little pieces, but I just could not get the jetting issues even close. I also bought a set of 4 emgo pods, after the fifth time pulling the carbs I could not take wrestlin with the air plenum again.
              When I looked at the parts list for the 1100E kit (there was an 1100G KN kit on ebay, and I was being hopeful, oh well), I did not see a pilot jet, is this not usually needed with pods and a good exhaust when using the stage 3 kit?

              Thanks
              Derrick

                According to the directions for the 3133 kit, pilot jets are included and optional. I left the stock ones in when I jetted my bike. The instructions say the supplied pilot jets will lean out the bottom end if the bike starts with out a choke. I need full choke to get mine started.

                Here is a link to a pdf for the 80-86 1100 and 1150's kit

                  OK, wemt and reread the installaition PDF, they are talking about the pilot air jet , I was refering to the pilot fuel jet that is installed next to the main jet. Does the new needle afect the fuel flow at idle enough to keep it from leaning out?

                  thanks, ( hoping a jet kit will free my bike from the carport )

                    At idle the main jet circuit is completely closed so no.
                    My kit didn't have pilot jets either and it runs fine, more the nfine really, picked up 12 hp with the pods and Yoshimura pipe.

                      Just a word of caution on the neighborhood re-jetting test rides. On a few occasions when I had my jet needle lowered too much I would get no power at all off idle. But as the rpm's rose a little and I opened the throttle a little more, then -WHAM, the power would suddenly come on and it felt like being shot from a cannon. Just give yourself a little room when trying out the new jet settings.

                      Please let us know what your final jetting specs are. I've been thinking about trying the single cone pod setup. TIA

                        Thanks for the help guys,
                        well UPS has hosed me again, I pay for 2 day air and the package gets "delayed" in Jacksonville, so now it will be Monday (I get the special price for 4 day air) before I get my Jet kit. What can possiblly (besides negligence) delay a 10oz package? They will be my absolute last choice for shipping from this point on, the unguarenteed 2nd dar service from the postal service has been more consistant.

                        Sorry folks, just a little venting
                        I will keep you posted on my Jetting adventure,
