New to me 1982 XJ1100

[Arthur6]

1982 XJ1100
Fuel lines are off(??)
silicone on the intake flanges
no battery
header was off the bike(??)
33,000 miles - we'll see what happens.
Turn signals relocated for saddle bags(I see where they go)
Where should the fronts be?? (PO included a SlipStream Windshield)
Thanks, Guys

Looks good in the pic Arthur. Don't even worry about the cosmetics until you get it running.

You might want to keep those rear turn signals where they are and the soft bag supports too. You'll find after you've ridden it for a while that you'll want the storage. Throw a set of leather bags on there to carry stuff.

Looks like the front turn signals are on there. What's the problem?

The xj front turn signals are usually mounted to the headlight bucket, but the look good where they are mounted. Looks like you have a good base to start with. Both of mine were in much worse condition and I’ve gotten one of them running good. I'm sure you will have that one running in no time.

[Arthur6]

Charging the battery now, turns over but slow.
Need to hook up the fuel lines, I see several ways to do it on here.
I do understand the vacuum petcocks, may by pass that Octopus thing for now tho.
I've had several other bikes like this (82 750 Spectre, 81 CB1100f, 550 Maxim)
We'll see what this brings.
Any advise will be great.
Back-up plan is get it looking OK
IF I can't get it running, sell it as non-running.
Done that a few times too.

None of the modesl have both vacuum petcocks and the OCTY (vacuum valve). Your XJ would have teh OCTY valve, and manual petcocks.

Hi Arthur,

Looks like it was well cared for. If the fuel lines are missing, you will probably need to go into the carbs for a good cleaning. You also want to be sure that the oil is good before you try to start it. If there is any fuel in the oil you will destroy the bearings.

So the OCTY valve is the vacuum shutoff - right?
I'll hook up some fuel lines with my remote gas bottle and try and start it.
Anything I should know??
Battery is charged and it does crank over.
I'll check the oil, maybe change it. How many quarts does it take?
I don't want to invest too much till I see if it runs.
PO said he was riding it daily about two years ago, told me he cleaned the carbs and it ran well. He didn't say why the fuel lines were off. He did say his teenage son wanted to get it going about a month ago but quickly lost interest, I'm assuming that's why the lines are off.
Bike shop wants $4.95/ft for 1/4" fuel line, I think I need 3 ft. I'll buy some at the hardware store for now, I know it's not for gas.

[BA80]

Go to the auto parts store and get some tygon fuel line. OReillys has it, just ask. Your gonna need more tha 3 feet if you use the octy.

Nice find and welcome to the group. You'll find a whole lot of great help here. if you browse around the tech tips and search the archives you'll find a wealth of info.

Cheers!

My advice would be to get a centerstand for it. only check your fluids with the bike verticle and not on the sidestand. nice find

I just went through the process of restoring an xj1100 82.

The petcocks are manual shut off. The octy does not shut off the gas when theres no pressure, 1 and 4 are alway open to each other and 2 and 3 are always open to each other. When its actuated by pressure the 4 open up to each other to help balance fuel flow between the 2 carb intakes. basically so if youre running low on fuel, the way the tank is designed only 2 carbs would get fuel without this octy. or if you were to lean to far and stop gravity feed from one side.

The headlights are supposed to be mounted to the headlight bucket.

Drain the oil and check for metal fragments, put some 20w-40/50 rotella oil in it. Put the whole 4qt container (should be $10-14).
Trickle charge the battery and make sure its 14~ volts and holding. Completely break down the carbs and give them a good cleaning and soak. Get new good fuel lines. The diagram for the fuel line layout should be on the bottom of the seat. If not i can post a picture. It should be both petcock ports to the rear go straight to ports 2 and 3 on the octy, and the forward ports T-split to the octy and carb fuel intake.

Let me know if you have any other questions.

Once you got it running, pray the 2nd gear fix was executed.

The Octy DOES stop the fuel flow when there is no vacuum from the engine. That's the main purpose of it. Unless, of course, you set the petcocks to "Prime". When the petcock is in the "on" or "Reserve" position, fuel only flows to the Octy, then out to the 2 carb inlets. If you switch to "Prime", the octy is bypassed, running fuel directly to the one carb inlet on that side.

If you choose to remove the octy as some have done, you just need to be sure to link both petcocks, because if you don't, as Wouldstalk stated, the tank will separate the last portion of fuel and only feed one side.

Huh thats interesting, i can blow through mine with very little pressure and have flow through, but like i said only from 1 to 4 and 2 to 3.

Right. Because 2 and 3 are the fuel intakes for the octy and 1 and 4 are the outputs. You connect the Prime port on the petcocks to a tee in the hoses in the middle of the output lines which allows the Prime port to bypass the octy. If you apply a vacuum to the octy, you can blow into 2 or 3 (block off the other one) and the air will flow out of 1 and 4 at the same time.
