Interested in a touring wind screen that is a bit higher/extended over stock to fit on my 1986. I'm not too concerned if it's scratched up as I may black it out anyway.

Ohhh, this is shaping up to be a classic!    I, of course...will be there with all the requisite bells on. 

Will be great to see the old friends and make a few new ones...See ya there!

Cap'n Ron. . .

 A good color coded complete wiring schematic really helps. I keep a copy of it in my tool pouch and a picture on my phone. The Yamaha owners manual that comes with the bike has a complete schematic but its point to point not set up like a ladder diaghram also very small and hard to see without a magnifying glass.

Thanks again.  I found the circuit diagram in the service manual unnecessarily confusing regarding the wiring around the diode and the clutch switch.  I see that you've used white out and redrew some of the wiring lines on your marked diagram to clarify it.  I found your version of the electricial circuit much more useful than what is in the service manual. 

Also, the testing information for the side stand relay, on page 6-18 of the service manual, is incorrect.  The manual says that the relay contacts should close when the coil is powered up, and open with no power to the coil.  That's wrong, the relay contacts are closed (0 ohms) when the coil sees no power, and they open when the coil is powered up. 

When trying to figure out a problem on my bike I too found the diaghram in the factory manual didnt make sense and couldnt possibly work as drawn. I redrew the lines to make it work . Later I traced out the wiring diagram in the owners manual that comes with the bike and found that it matched my redrawn schematic and that the factory repair manual was incorrect.

Quote from: T Legg on February 26, 2026, 01:45:37 PMIt could be a bad diode in the diode block #27 on the factory manual schematic.The kickstand relay contacts when closed ground out the ignition control and prevents the spark plugs from firing. When the kickstand is up it closes the switch and gives the kickstand relay coil a path to ground energizing the coil and causing the relay contacts to open up ungrounding the ignition module and allows spark. There is a second path to ground for the kickstand relay coil that goes through a diode to the nuetral switch to ground. If that diode goes out then the only way to ground for the kickstand relay is through the kickstand switch.

You may be onto something.  I'm looking through the wiring diagram and circuit diagram and if one of 2 the diodes that supply current to the neutral switch failed open (no current flow), it might explain what I am seeing.  I'll need to pull that diode block and test it with the wiring diagram.  Good thought.  I'm away from home at this time and returning in a week.  I'll report back. 

Resolved.  Got home last night and tore into that this morning. I pulled the diode block off the bike and tested both diodes that are connected to the neutral switch.  Sure enough, the diode between the Blue/Yellow wire and the Sky Blue wire had failed and had no current flow in either direction.  Other diode tested fine. I had some 1N4001 diodes at home from another project, so I bypassed the failded diode and spliced in a 1N4001 diode between the two wires.  Works as it should now.  Good call T Legg. 

I've got a old set of the RS flat slide, with the infamous sticky slides I guess.
They were set up for methanol and nitro, so I need to either adapt them for E85 or install the conversion back to gasoline, which I have, somewhere.....
I'm glad to hear these work well

Yes, i've also got a 17 x 3.5 front wheel and complete front end, including the 320mm discs,from a XJR1200 on my FJ.
The handling is great compared to the standard FJ set up, and i've also put the damping adjuster from the XJR1300 on the forks, which are 43mm compared to the FJ 41mm. Sorry about two photos but the second photo enlarges when clicked on.

As you sit on the bike starting from the left they are 1,2,3,4 .
  It really doesnt matter though if you start from the left or right. One coil goes to the two outside plugs and the other goes to the two inside plugs. since its a wasted spark set up both 1&4  plugs fire at the same time and 2&3 also. The plugs fire on each cylinder on both compression and exhaust strokes.

I hate ask because I know it's in here somewhere I just can't find it, I searched both manuals and this forum and can't figure out how the spark plugs are numbered left to right. They come out of the coil as 1,4,2,3. Is that how the cylinders are numbered? Thanks
