Intro and Problems Running

[Laptop_geek]

Alright, I tried using heat and suction. I boiled the carbs for about 20 min then placed them in the container with plastic cup inside of it (to keep the container from collapsing) and that was a no go. They didn't look like they had a leak in them when they were in the water.

XS, it wouldn't matter if I did only one side of the float as it is a difference in pressure that is causing the floats to pop out. The pressure is the same over the whole piece no mater the surface area. Unless I miss understood you and you were talking of something different.

It does work

Compressed air pushed it in, vacuum will pull it out. As to the posti-vac, I have "heard" they also have other uses I was "told" they are one toughSucker, just hear say from here

Most shop vacs will not pull much more than 7 to 8 inches of vacuum. (Inches of mercury)
Most car engines will pull 12 to 18 inches at idle.
A hose run from the intake manifold to your jar (glass) will give you more suck than the vacuum. Might do the trick.

Wow, good info. I calculated the area of the side of the float to be about .8 in2. That would give a distributed force pushing out on the side of the float of about 4.7 ~ 7.1 lbf using a car intake vacuum. The maximum distributed force that could be created is about 11.8 lbf. Wonder if thats enough to push these things out... Anyone know how much vacuum a pos t vac makes?

I drained the tank (took forever) and took off the petcocks, they were all clogged up. So i took them apart and cleaned them up. I'm going to put them on the other tank that came with the bike. Its looks like some one coated the inside with POr-15 (or similar), no rust and everything is white, only problem is it has a small dent on one side of it. This brings up the question, do these tanks have a double layer construction? If not fixing the dent is a piece of cake, if so, what is the easiest way to pull it out? Any ideas?

Pos t vac

I think the record is 12 inches, Oh, inches of mercury, about 30+

Nope, single-wall tanks. Don't bother trying to pull the dent (particularly if it's been lined) as you can rarely get good enough access to pop them out, just fill it with bondo. Take to bare metal with a 36 or 50 grit disc to make sure the plastic sticks.

Got the petcocks on the new tank, and they started leaking. I tried to deal with it to see if I could make it run, and I couldn't. So I drained the tank and have to take the petcocks apart and replace the tank seal. Then I'll follow some advice from the site and put a little lube on them and recheck to make sure it all looks good.

I'm going to go through the ignition system and see if there is something there that is not working. I started to check the coils, but my cheap multi meter went out, so I guess its time to invest in a good one.

Here is one thing I'm wondering about. Does the green wire coming off the starter solenoid go to anything important? I'm assuming that is one of the things that got fried.

Hmmmm, you've been POed...

That green wire is supposed to hook to a red/yellow from the TCI. It supplies 12V to the coils when the starter button is pressed; under running conditions, the coils are fed through the ballast resistor at a reduced voltage. And you've got an 'extra' wire connected to the starter terminal on the solenoid, you might want to track that down and see where it goes (and supposedly does).

The wiring on these isn't all that complicated, but you can find real messes if somebody didn't know what they were doing. It would probably pay to spend 3-4 hours and trace the various circuits out to make sure they're still going where they need to, and don't have any PO-mods that shouldn't be there. Here's a troubleshooting guide: http://www.xs11.com/forum/showthread...roubleshooting, look in the unit repair section of the manual for easier-to-read diagrams of the individual circuits.

Good luck!

YES!!! I think that means I've found the problem. I went to sears and bought a good multi meter, so now I get to try it out!

Is that tin foil covering that accesory fuse ?!?
(even though there's nothing hooked up to the accesory circuit?)

I did notice that it looks like the stock turn signal flasher is there.
That's a good thing as those are getting a little rare.
(at least if you want to keep the stock self cancel feature)

Yes it was, I am thinking the old fuse block looked like that before it was fried and thats what fried the wiring. I'm hoping the PO didn't kill the TCI unit. Haven't have a chance to look at it yet, but I'll update when I do.

Welcome and....

HI!
Going thru the same here. Thought it was a 79, but found out its a 78 a few sites I found helpful, this being the best, the guys are great!

http://xs1100.com.au/forum/index.php?topic=870.0

This has jetting per model.
http://www.zrxoa.org/forums/showthre...an-carbs-(PICS!) this one is similar to our carbs, and the pics are good. I took every part out, if I hadnt found the site that talked about the emulsion tube , i would have had to do them twice They were blocked....this link is to the "fun" Im having

Sounds like you've been having fun Sparkett. I'm going to bookmark those links, they'll probably be useful soon. I did check all the jets in my bike and made sure they're all the same. One of the carbs had a jet that was different from the others, but i was able to fix that with the spares that I have. I'm still not sure what year this bike is. I'll have to look up the VIN I guess.

I got it running today. Fixed the wire (the R/Y wire from the harness was still intact) and it fired right up. It was not hitting on all the cylinders though. So now I've got the figure out why its doing that. I'll check all the easy stuff first, then move on the the harder stuff. First off I think my fuel line has a kink in it that maybe causing some of the problems. I'll get that fixed then go from there. Really glad to have it running now, thanks everyone for all the help so far.
