    Frustrated. Carbtune help

    So I finally got time to tune my carbs today, went to thread the adapters and I stripped one out...tried to be careful but my short fat hands just couldn't get it to go in there. I am going to be ordering the brass from Z1 and I just wanted to double check that they are 5mm adapters correct?

    5mm is correct. The plastic ones that come with the carbtune are pure junk. The brass ones will work out great.

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

          If you put a length of stiff tubing on the plastic ones they go in and out easily every time.

              Attempted to sync tonight

              Well I attempted to sync the carbs tonight, my first try I royally fudged them up, got the #1 and #2 vacuum lines backwards ended up with #3 maxed out on the carbtune so I pulled them and did another bench sync, I can get close #3 sitting about 20cmhg and #2 around 18cmhg get #1 just above that and when I got to adjust #4 the bike starts to stall, dropping from just under 2000RPM to under 1000RPM. Tried again and got it to stay up near 2000RPM and got #4 just above #3 but then #1 dropped and as I brought it back the RPM started climbing.

              Thats about what I can recall it was a PITA to keep the RPM steady, is this because the bike wasn't warm enough? I let her get warm but its only about 35F in the garage right now so I don't know if it was staying warm enough.

              Any input is welcome, I am done for tonight. Frustrated, cold and sick of the exhaust smell.

              I have re-read the procedures on here and Bikecliffs site, I don't think I missed anything.

                If it was warm enough for the bike to be running off-"choke", it should have been fine.

                Did you remember to plug the vacuum port on #2?

                  That's what I thought about the warmth, one of the only things I could think of.

                  I did have the vacuum tube closed off as well.

                    Got her sync fairly well, will check in a couple hundred miles and see how it.is.

                    Took her out and ran nice and smooth better than it has in a while.

                    Thanks again for the help Steve!
