The video I promised post about my 90 Yamaha FJ 1200

This is the link to the video that I said I would post about what's going on with my bike. This was from the introduction post 'new kid on the block'.  https://youtu.be/AM1eBs0HWh0 see what you can decipher from what's going on because I'm still not sure yet and I want to know what parts I should and should not buy just to be safe already bought a new slaves on her but I'm not sure if I need it.

That's your sidestand safety switch doing what it's supposed to do, cuts the motor out when you put it in gear so you don't ride off with the stand down. Try it sitting on the bike with the stand up, if it still does it the switch is faulty.

Your clutch seems ok, it looks like the side stand safety circuit is your problem. You can roll the bike in gear and the clutch lever pulled in, also indicates your clutch is disengaging as it should. look for the side stand switch, follow the wire and make sure it is not cut or damaged.

Okay on further investigation it seems that I have a new problem I lack the kickstand switch so I'm guessing the bike cannot run without it unless the wires are tucked in the bike somewhere I have no clue where they are

Yes that is definitely the side stand switch causing it to die as you select 1st gear.... I think it is normally open with the side stand up so maybe the wire to it is broken somewhere and permanently grounded?
The grinding you hear are the 1st gear teeth coming into mesh. Even with the clutch disengaged, there is still some friction due to the oil between the steels and fibre plates in the clutch which is slowly spinning the gearbox input shaft. A quick blip of the throttle prior to engaging gear will help with this - I believe it is not abnormal and nothing to be concerned about.

Ok, that wire goes to the igniter box..... let me see if I can figure out the colour of the wire and you can either cut it or ground it (depending on its requirement for operation)...... I will post back soon.

Some pictures of the kickstand. Is this switch supposed to go for that empty bracket is

[Harvy]

Correct!

[Bones]

The switch is pictured below the oil filter and the wires to it have a habit of getting caught under the standard oil filter cover when reinstalling it. Have a look to see if the wire is pinched under the cover.

The side stand switch wire is blue with yellow stripe (on my '91 - probably also on '90). It goes to the 6 pin connector on the ignitor box.
The circuit diagram shows it to be normally open, so my guess is that it is already connected to ground somewhere.

Okay cool the only thing now I have to do is to find the ignitor box and once I find it disconnecting it and then putting a new one there should be cool and have everything working smoothly right. Also if I find that there is a wire but there's no switch should I ground it out

Also thanks guys for all the help

Josh, on your '90 there are a pair of wires that go to your missing sidestand  switch....these wires are blue/yellow and black. Under your left side cover there is a connector plug for these wires.
Take  a small piece of wire and put a spade connector on each end to make a jumper wire.
Now, disconnect the plug and with your jumper wire, connect the spades to each male prong on that connector.

Again, you are looking for blue/ yellow wire and a black wire....tie the two together and that will bypass your sidestand switch....it's easiest if you find the connector plug and do it at that point.
Easily reversible when you buy a new switch....

Hope this helps.....if you don't already have one, get yourself a Owners Handbook for your '90, it's free.
The wiring schematic is in the back of the handbook.  See my signature line....Cheers. Pat

I went and took some pics but looks like pat beat me to the post.

So to clarify .... the sides stand switch contacts are closed with the kick stand up and they open with the kickstand down. so to bypass it use the jumper Pat was talking about on the male terminals.

here are pics of my 86 and it will be similar.

Cool nice thanks guys again Lifesavers. Sure I follow those wires and found it tucked over by the engine also I did this real quick I have The correct butt connectors but I'm going to just twist them up just to see if I could drop it this bad boy into first without it turning off just so I don't blow anything up ha ha, is this okay
