    Jessie doesn't fire on 1 and 4

    Good day everyone,

    On my way to work Tuesday my GS850GT lost power a few blocks from home. I was able to ride it home. Yes, I had to drive my truck to work most of the week. Bleh.

    I finally had time to do some troubleshooting today. I pulled the spark plug wires one at a time and used a spare spark plug. I found out it was not firing on cylinders 1 and 4. I then took off the left coil and found this...



    The hot wire came loose from the top of the coil. After I clean it up a bit ( ) will I be able to re-attach that wire to the coil? Or is it time for some green coils?

    I'll keep you posted. I'm going to try to re-attach. But it looks like there's some kind of epoxy to dig out of the way first. Thanks for your time.

    Thank you for your indulgence,

    BassCliff

        Dynas are a waste of money. I had one go bad after just a year and have used later model Suzuki coils ever since. I'd try reattaching the wire first and see what happens.

          Most of the coils I have from stock zooks are clipped on??? Why is that one different?

            I have some spare coils too Cliff, if for some reasons Lynn's don't work out.

              The operation was a success!

              Hi guys,

              Thanks for your generous offer too Ed. The fix turned out to be simpler than I thought.

              After I cleaned the area I found there was some epoxy over the connection. I carefully chipped it away with an exacto knife and discovered the solder terminal underneath.



              I un-soldered (de-soldered?) the broken wire and re-soldered the coil wire (after tinning, of course).




              I trimmed it a bit then used a slice of green epoxy, sort of like the kind that Billy Mays sells, and covered the connection.




              I put everything back together, touched the start button, and she fired right up. I was so happy I gave Jessie a bath.





              Now she's running good AND looking pretty good again. What I've learned from this community made this a really simple fix. Thank you all for your guidance and friendship.

              Thank you for your indulgence,

              BassCliff

                    Suzuki swapped back and forth, some have spade connectors some have soldered on leads. kind of a hit and miss on what you will find.

                      Hi Cliff,
                      Can I ask where you got the engine guard and highway pegs? I have an 81 GS1000 GL and would love to put those on.

                      Thanks,
                      Mike

                        search "case guard" from the parts group menu

                          Hi Mr. redmike,

                          They were on the bike when I bought it. But you can still find them at http://www.denniskirk.com. If I set it up properly, just click the picture.



                          The spec sheet says they'll fit your bike too.

                          The highway pegs I have are more like these:

                            Thanks BassCliff and Hikermikem. I'll order them up once I figure out how to address my carb airflow issues.

                            Much appreciated.

                              Man I love this place! I had no idea and was driving myself nuts trying to figure out why my coils were different from the ones I researched for my bike.
                              Mine has spade connectors.
