    1977 GS400 help with mystery of the right ignition points

    Here is the GS400 wiring diagram, in color, I found on BassCliff’s page: https://onedrive.live.com/?sc=documents&cid=2370B62DDF9F0C6B&id=2370B62DDF9F0C6B%211033&parId=2370B62DDF9F0C6B%211030&o=OneUp

    1977 GS400 help with mystery of the right ignition points

    Okay, forget what I wrote above. I found a GS400 wiring diagram and I see that the GS400 has dual coils. The GS400 feeds the ignition coils roughly battery voltage and the ignition points provide ground side control of coils. What that means is most of the voltage is dropped across the coils...

    1977 GS400 help with mystery of the right ignition points

    Okay, please note that this is coming from an old Ford Flathead guru. Looks to me like the right hand set of points is open. If a GS400 is a twin cylinder? And a parallel twin at that?, and both pistons go up and down together, then that ignition system may use TWO sets of points to make the...

    No Spark either side till i release the starter button

    This is interesting. When you jumper the Red and Orange wire to bypass the ignition switch contacts, AND let the ignitor turn the coils on and off while engine is being cranked by jumpering the starter solenoid NO Sparky at plugs. But in a previous post where you supplied power AND ground to...

    No Spark either side till i release the starter button

    Here is a longer version with actual voltage drop testing. Note that it doesn’t mater if the circuit being tested is the starter circuit, or the coil circuit, hone circuit, etc. Electricity is electricity. https://m.youtube.com/watch?v=DfLyh43iihM&pp=QAFIAQ%3D%3D

    Racing idle 1977 GS400

    Where is your fuel level? You might be able to lower the float adjustment a mm or 2 (which would raise the fuel level in the float chamber) and make it easier for the existing pilot jet to draw in a smidgion more fuel.

    Oh, okay. Thanks Rich. I didn’t realize that on your machine that the tool bag plate goes over the top of the solenoid and fuse box. So to access your fuses you just take off the tool bag plate. So if it ever cools off here in Upstate NY I will have more ideas to sort this “real...

    Gs550 1979 led blinkers flash erratically

    What has changed? Might be time to fire up the amp clamp and measure the amp load going through the flasher with and without the engine running. I would also try running the R/R output directly into the harness load instead of to the battery + post. Could just be that the battery draw AND the...

    Cylinder three running extremely hot

    The intake air going through the carburetor creates a vacuum that “lifts” the fuel out of the float bowl into the various channels in the carb. The higher the fuel level in the float bowl the easier it is to “lift” the fuel a very short height. The lower the fuel level, the vacuum has to “lift”...

    1982 GS750T cranks but won't start

    I’m trying to follow along, but do you mean you timed the cams according to the manual? Or did you time the ignition? Maybe you did both? Perhaps you could give a somewhat detailed description of just what your “rebuilt from the ground up” entailed.

    1982 GS750T cranks but won't start

    No fire even with starting fluid, I’ll take that as an ignition problem, but would feel better if you had laid a spark plug on the cylinder head and cranked it. Did this ground up rebuild have any impact on cam timing or valve lash?

    1982 GS750T cranks but won't start

    Are the spark plugs wet or dry? Is there fuel in the float bowls? Is there spark at the business end of the spark plugs?

    82 gs850g loses spark

    Sounds like that is the ground for the starter relay. Prolly goes to the fram to ground the starter relay. (Note: I don’t have a wiring diagram to verify that wire color).

    System Relay Mod

    So, here’s my SWAG: Your original relay went bad. Not sure just what type of relay it was. It sounds to me like you have one ignition coil wired to pin 87 and the other wired to pin 87A. It also sounds to me that your pin 30 is hot at all times, even with ignition switch off. With your...

    Bogging down gsx250e after a mile always and stops

    If that R/R seems very hot, will the R/R from your GS550ET be made to work temporarily on your GSX 250E?
