As I said early in this story, my 84 has a problem with the wires leading into the cut off relay 41-71r behind the fairing ,, until I do the wiring I've fitted a small momentary switch next to the seat just for those times when the switch dousnt respond, ,

Kyle,
On the schematic diagram it shows the main relay (#11) getting "coil" (activation) power by tapping off of the main lead from the battery. So there should be power getting to the relay.

One of two things may not be happening. The Cut-off relay may not be letting the main relay coil power rgo to ground. The starter switch is the ground path for the main relay. But it will only work if the Cut-Off relay is working. The other thing is the starter switch may not be grounding (broken wire).

What I propose is getting on the ground side of the main relay and installing a switch to provide a ground path for the main relay. Essentially this will move the starter switch in front of the cut-off relay and eliminate that relay from the circuit. This is all temporary and can be fixed when you get home.

You can remote a simple toggle or momentary contact switch for this function. Put the switch anywhere that's convenient, it will work as your new starter switch. If that fails to make the starter turn over, then the main relay/solenoid is bad.

Look for a bullet connector with a Blue with White Stripe wire. It should be coming off the bottom of the main relay and looping up by the frame just behind the battery. That is the wire you want to either ground or attach a switch to and run it to the negative battery lead.

Glad to hear you got it up and running

)). You can set the idle up a bit if you feel more comfortable for a while. At 1000 RPM you are at or close to spec's.. Just for information only, standing on the right side (throttle side) take a flashlight and peek under the front bottom of the carbs, in the middle you should see a notched adjustment wheel. That's the idle adjustment... I usually use a long screw driver to push the wheel around to adjust the idle as it gets kinda hot for the hands and the space is small. In a pinch a small stick would do. Improvise,Adapt and overcome.
The link below is a fleebay site showing a carb set for sale. Check out the second photo down and you will see the round notched idle adjustment wheel so you know what to look for.

I had already seen it and hoped I was wrong in assuming that was it. Alas. That's quite a pain to access, haha. Was planning on doing it soon. Clockwise pushes the idle up, correct?

And as a somewhat embarrassing treat, here's the video I was filming as I got her running for the first time. Warning: has not been edited, kind of longish. But features the bike's first start-up and brief ride, as well as some maniacal laughter! haha.

Should be up in a minute or two.

Also, some more pictures of me trying to short the safety switches:

Also, this: Do I have the california model? See this under the seat, and I know the owner before the previous owner was in Nevada... And that I'm the fourth owner...

As for your suggestion, David, I think I get it. What kind of switch would you recommend?

I suppose this should be a plan B if just grounding the black/yellow wire doesn't allow the starter button to just work?

How much of a hassle is removing the fairing?

That last image in non-link form...

Sounds good .. I don't remember which way the screw turned for increase or decrease but it will be self evident. Just find a screw driver with a long shaft (8 inch's or so) to nudge it, it adjusts easy. Is just kinda hard to locate if you don't know where it is. Its not like you have to adjust it often. And you can do it by hand if you are careful, you got to be quick, it's hot in there.... And you should adjust it after the FJ is warmed up.
In a tight spot until you can get the FJ cleaned out/carbs rebuilt/tuned up or what ever it needs to be reliable you could give it a shot of starting fluid to help fire it up if its a problem. During the summer mine seems to start up better if I crack open the throttle a little (not twisting it, there's no accelerator pumps in the carbs) (my carbs are probably slightly rich), during the cold weather I just pull full choke leave the throttle alone and it fires right up. I let mine warm up for a min (don't get in a hurry) then step down the choke about half way and when the RPM stabilizes then pull the choke all the way off. You will find a "drill" that works for you.
Better get out of there before webbing starts to grow between you toes and fingers ......

Glad to see you've got it running......at least good enough to ride it .
Looks like a nice bike once you sort it out...........Love the laughter in your video.
Kyle, You've definately got some balls trying to pull this off the way you have. I'm pulling for you to make it home........
I have no doubt that you will.......as long as you can keep in touch with the group on the forum, especially with the more knowledgable members here, you should be fine........
Before you head down the highway towards Portland, you should at least ride it around Seattle for a longer ride...............Say, 2 hour ride or so.........make sure it's going to run while it's good and hot, before you head away from the safety of the city, and your friend to come get you.

Here's to you, and your new FJ making it home in one piece!

aviationfred · October 31, 2012, 11:24:47 PM

Watched your video, Nothing to be embarrassed about. The bike looks very clean and well taken care of. I think you got a great deal on your hands with many years of FJ enjoyment ahead of you. I am a machinery Electrician by trade. I know electrical systems on motorcycles and cars can easily turn into a nightmare. I don't even bother with cars, they go to the shop. Motorcycles I will troubleshoot and fix when needed.

Awesome job getting the bike started and running.

It does look nice

If the starter relay is like the ones in my waverunner it will melt inside if you crank it too long.When the plastic melts inside the contacts can no longer touch each other.Dont crank on it so long to start it.
Good chance the relay is bad.

fintip · November 01, 2012, 12:34:28 AM

The relay unit or the 'main relay'/solenoid?

Yeah, in retrospect it was a bit hard on the bike. On the other hand it is a brand new starter.

Flying Scotsman · November 01, 2012, 12:59:05 AM

The round one you were hiting with the screwdriver.Long story but I melted one in my waverunner.Took it apart and the plastic melted so the contacts couldnt move to touch each other.

fintip · November 01, 2012, 01:17:37 AM

It was replaced, had never been used when I got the bike. I am pretty sure I still hear it clicking, but I'll check it. Anything's possible.

fj11.5 · November 01, 2012, 03:17:01 AM

Cool vid mate, she looks fairly standard, , thats a good thing,

Kyle, the easiest way and the one with the most control is with a gloved hand.
The trick is to open the throttle slightly to take the load off the screw so it turns easily, same if you want to use a screw driver, which I find a pain.
I can, and have, adjusted mine while at a red light.

,, yep easy to adjust, even at lights, , pays to have small hands, even with summer gloves on
