If the plugs are not earthed then they will not spark. To earth, simply hold then against one of the cooling fins, or any other bare metal part of the engine. I prefer a shaded location so it is easier to see the spark.

So... I was told by someone that not having your spark plugs connected while turning over the ignition can overload the circuitry of an electronic ignition. That was generally confirmed by pamco pete (He blanked agreed with all the ways I was worried about tanking the ignition. He didn't specifically agree with that one.) I know that a spark plug won't fire if it isn't grounded.  ;) I'm at least that far along in my learning.

I've also realized that I didn't check to see if my slide was jammed again. That has been happening occasionally. I can usually work it out after a few repositionings of the rubber replacement boot. I'm wondering if I should carve out some material from the bottom of the slide on the lathe to keep it from happening again. I was also thinking about installing a thin o ring as a bumper, but that would move my needle up by the thickness of the o-ring. Doing that seems like it would be a huge shift in tuning (which based on the strong linear pull to redline when it did run last week would be a step in the wrong direction overall)...

Thoughts? I'm no machinist, but I have the machine. (I've got soul, but I'm not a soldier)

4: Check slides (pull airboxes. Poke fingers in the air side. Feel for free movement.)

If you see me f**cking up it's because I have no idea what I'm doing. You can either tell me I'm fucking up or watch me find out on my own. Both are appreciated.

Strip a couple inches back on a wire and wrap it tight around plug threads. Trap other end under a bolt head on engine or frame.
Then you can safely check for spark.



If you dont have the slides vent holes facing towards the filter, they will "hammer" themselves to death in the bore and this will cause sticking.

Look closely around bottom edge of slide for shiny spots or any roughness. 
Use a fine file or emory paper to sand smooth.



After I sanded them smooth.



I had to use channel locks to pull the slides out of bodies.  I use a piece of scotchbrite to smooth bores.

Thanks, Eric. That’s a great step by step. I should be able to dive in and tackle that this afternoon. I also finally managed to get those CL mufflers to slide on. Had to weld a new piece to the one that was factory welded and track down the carbon gaskets (all praise be to common motor). They sound really good. Thanks for sending them along way back when.

Glad the mufflers are worked out.  That was a long time ago.  Forgot I had sent them.  They look super.  Keep us updated w what issue you find.

So I took it to the shop and they turned it away. Too much wrench time with an inexperienced mechanic (fair). They did say:

Fuel smells old..

Got back to the bike this morning: drained the tank and tested the ignition with a test light. Full cycle and the right timing  performed well (light cut out once per rotation) and the left one stayed lit the whole cycle.  That’s likely my problem. I also have a sticky slide, so I’ll be pulling my carbs off an cleaning them up per Trek’s how-to

Not sure how I could have fried the ignition. New rectifier and new ignition (matched). Gonna do a few more tidying bits while waiting for a replacement ignition. The blinkers and parking lights work great, but there isn’t space in the bucket for the flasher relay. I’m gonna move it back to under the seat. I’m also going to go back to a stock battery size and fuse box. The Ascot has a brand new AMG in the CB360s factory size. It won’t need it until I figure out why the engine failed. That might take another 8years, lol.

Just quit my job to consult, so I’ll have a bit more time between now and Christmas to throw at both of them.

Electronic Ignition.

I probably called something the points up there by habit. I still call the blue and yellow connectors at the coils the "points connectors" and am having trouble relearning.

I've been working on a custom rewire (masochist?) and I put this together from my hand-scrawled notes:

The rectifier is "Charlie's Place Type 1" Ignition is also Charlie's Place.



Any obvious errors in here? This gets the functionality I'm looking for out of the Kawasaki "pass" switch I've got for this project. Without the relays (waiting to install them later.) I'm just tying the hi beam to the pass switch. Pass only works with the low beam on. With one relay (Yellow, white, brown) I get flash if the lights are off or hi if the lights are on (90%) The second relay adds a "cut high beam" if I hit the pass button and the high is already engaged.

Charlie from Charlie's place tested the original ignition and I should have a replacement in a day or two. The wires were pinched in the cover. I have to be more careful about that.

Coils are 12Kohm/ 5.4 ohm in the left and 12K ohm/ 5.0 ohm on the right. Both of my caps have the correct resistance.

I'm pulling the new 12A battery from the other bike to put into the factory location. I'm hoping the extra amps will help me make it through longer stop lights with the factory charging system. I can always opt to kill the lights if I'm sitting for an especially long time.

You'll want brown and not brown/white for your parking circuit. And I don't recommend using the turn signal for the parking light, since the ignition switch will have power running through the brown wire when the switch is in the ON position.

Also, the stator isn't three phase, it's single phase, so you should have a separate yellow, pink, and white wire and not three yellows.

What's the purpose of the DPST switches? Is the dimming not being toggled with the KZ control?
