    Timing Dyna-S on 82 gs650

    Installed a DYNA-S Ignition on my 1982 GS650GLZ. The Dyna instructions say to time with light at mark to the right of F mark. Which timing marks are you suppose to use on the mechanical advancer? This is stamped on the 1-4 side "|T |F 1.4 |" . The 2-3 only has "2.3 |" and the mark is not 180 deg from mark on 1-4 side. I set the engine mark at the 1.4 and 2.3 since they were 180 apart. Bike seems to run well like this?

      Put the timing light on the #4 wire and time to F1-4 at 1K rpm. There is a second mark that should be lined up when the advance is fully advanced at around 3K rpm.

        Took a picture of a spare advancer I had and noted how I set and how I interpreted your notes is this the mark you are recommending I time to at 1000RPM. Based on the advancer it looks like I got close by blind luck?

            if they recommend you set it at 41000rpm then you got no chance of getting it right haha

            Just remember, an opinion without 3.14 is just an onion!

              That's the mark. Move the plate a little clockwise to get it right. See the mari after the 1&4? That is the advanced mark.
