pls help, I'm New

[fartypants]

Hello All,
got a deal on my first XS11 (80 XS1100G) and wondering what kinda deal I got !
I bought the bike, and it had its problems. Main one being it had caught fire. Apparently the carbs flooded out and dripped over everthing and it went up in flames. The previous owner had swapped out the carbs and airbox, and attempted to repair the harness. But it still had electrical probs.
MY QUESTION. I take it, the harness has to be replaced with one from the exact year and model ? I bought a harness from eBay and found the connectors in the headlight were not the same. I downloaded a manual , and it shows the wiring diagrams for the 80 and 81 as being the same. Are these harnesses the same? Any help would be appreciated.
ALSO. The front calipers were removed and tossed. Are all calipers the same? What model calipers will fit this bike. I think the "Special" calipers are different. right?
I am hoping to be riding this thing ASAP. really can't wait. THANKS

What year and model XS do you have?
That will help answer your questions.

I have an 80 XS1100G 3H5

I have an 80 XS1100G 3H5

Any pictures of the bike??? Usually the specials have a round headlight and a tear drop tank. Yes the special and standard models have different front brake setups.... if you got the wrong year harness that might be your problem with the connections.


pictures would help also and we all love seeing new bikes

My first XS was a G.
Took about two months for my opinion of the XS to do a 180.
After a surprisingly short learning curve (if your mechanically inclined ) you will find the XS to be a pretty "straight forward" machine.

If parts from different years/model are identical Yamaha used the same number. Some numbers will be close and may fit more than that particular model but color or something will be different.

Go here to see parts break down and find part numbers.

BTW, I just removed the harness of a G a couple days ago. AND no it's not available as I'm just in a slow process of fixing up that XS.

[fartypants]

The serial begins with 3H5 - so it should be a 1980 XS1100G

The tank is not a tear drop style. The head light was missing and it had a fairing on it. Now removed.

So, will any regular model calipers work for this?
and I'm assuming I need to find a harness for my specific model. I thought that since the wiring diagram for the 80G and 81H model were the same, the wiring harness may be the same. But I really hate ASSUMING.
Thanks Again

So, the harness you bought off EBay; is it a factory harness? One problem is these bikes can become 'frankenbikes' over the years with parts from multiple years and the title/vin won't always tell you the whole truth as to what the PO did. Does the harness have the 'right' number/colors of wires in the 'right' places, but the only difference is the plug connectors? You can change those; try here:http://www.oregonmotorcycleparts.com/connectors.html . He's a member here and sells many hard-to-find electrical items that work on these. Is the harness you have not even close? If that's the case, first you need to determine that the bike is still stock/original; if it is, then a 'correct' harness should be the choice unless you want to alter the one you have to 'fit'.

Same thing goes for the brakes, but here you only need to know which 'style' forks you have; standard or special. If the front axle is at the very bottom of the lower sliders, it's the standard type and calipers off any '78-81 'standard' will fit. These share brake design with many of the same-year 650/750/850 bikes as well, but most of these were single disc so you'll only get one side from them. If the front axle attaches to the front edge of the sliders and they extend to below the axle, then you have special forks and will need that type. They don't interchange between forks.

Same thing goes for the carbs; while they will interchange between years, the design changed slightly and jetting is not the same for all years. Also be aware of the float bowl venting; the early carbs are vented into the airbox, the later ones are vented internally.

All this help? Good luck, and welcome!

MRO - thanks for the link

and the info on part numbers.
I'll do some research and hopefully I will get some answers.

You should be able to use that harness. You may have to reuse your old harness plugs, but I'm pretty sure the color coding should work out fine. There are some differences between the special and standard. You might just have a special wiring harness.

Thanks Crazy

I know about Frankenbikes. I had a 69 sportster. A cross between a golf cart and tractor.

I got 3 sets of carbs for the bike. One burned up set. Which I think was the originals. (were jetted like the origs should have been) And 2 sets that are jetted like the 82. all Mikunis. They look clean, but i am going to clean them again and install. I'll be running pods, and I have 4into2 headers, so I was going to increase the Mains a few sizes. I've read allot of threads on carb jetting, so I know what to do there.

I've discovered the wire leads coming out of the engine are melted up, so I am reparing those while waiting for the correct harness to pop up on eBay.

OR does this site have a swap meet posting? haven't seen it yet if it does.

[fartypants]

The replacement harness had a couple thin connectors in the headlight shell. I have a large connector with about 9 small pins that didn't go to the harness.
It was different in the back also, and the colors weren't the same.

I would like to find an original harness, for a no-fuss swap.

80 to 81 harness

81's the year the XS's went to the 4R0 TCI, doing away with the mechanical advance and adding that function to the TCI. IIRC the wiring harness is a bit different. Seems to me like there's a different number of wires at the big TCI connector, and there are probably some other differences too. Is the old harness destroyed?

I saw several '79 harnesses on e-bay, but no '80's. Seems to me like a '79 would be closer to what you need, but not perfect. Maybe MRO will chime back in on it.

Well, if you fail to find a good 'correct' harness, maybe swapping plugs will be the next-best choice. I've done this on more than one bike, and just noted the changes on the wiring diagram. The electrons don't care what 'color' the wire is...

Hey fart......I love that,

Contact this member http://www.xs11.com/forum/member.php?u=42 with your VIN # and I'm pretty sure he can help you one way or the other.

andreas has LOTS of parts.

I really appreciate the help

The different harness looks like most of the important stuff plugs up.
I guess I could plug things in and see what doesn't work.

Looking at the Yamaha link that was supplied. The 80G and 81H have the same part number, but different prefix denoting year and model. The "special" has a different number.
I sent an email to a guy in the part out section for a harness, same year and model.
We'll see.
In the mean time, I have carbs to do, brakes to work on, and tire replacement.
Thanks Again
