Carb choke problem

[XS1100 Newbie]

I have been having a time figuring out my choke. For some reason when using the choke, it is getting to much fuel. I do need to use it for initial start, but then i have to turn it right off, and hold the throttle on for a couple minutes. I have been unable to isolate the cause of this. The balls are in the right place on the shaft, it works easy, the bike runs good, but it there has to be a reason the choke system is getting to much fuel. Any ideas would be helpful. Trying to get everything in order before selling.
Thanks

Leaky choke plungers? Rare but it does happen.

Did the little brass Start jets in the float bowls get reamed out oversize when they were cleaned?

I can't think of any way for them to fall out but are they all still in the float bowls and not MIA under the work bench?

Like Downshift suggested, the Enrichener plungers might be leaking but that would affect the engine when the Enrichener is off, too. The rubber tips on the plungers inside the carbs will leak when they get old and baked to a crisp, crackly crunch. The plungers won't seat if the yokes are out of position on the shaft.

It's easy to check the yokes but you have to split the carb bank to remove the plungers and check tips.

what happens

what does the bike do when the choke lever is in the second position from all the way engaged. Does the bike slow down or continue to rev high? The reason I ask is mine has always raced once warm in the full out position. In hot weather that only takes less then 30 seconds. Once I push the choke back in one detent it slows and then I give it a minute or two before fully disengaging and the bike idles from there. What exactly is yours doing?

Yup, thats what I was going to say. The enricher has two settings, all the way out is the richest. Try moving it to the first position after you start it with the richest setting. Then after a minute or more turn it off completely.

The pistons in the enrichment circuit can get sticky and not close off the circuit. When they seem to be working right they are not. Get a flashlight if needed, a long screwdriver/rod and reach in and push lightly on the end of the pistons where the clip on the choke rod grabs them to make sure they are closing all the way, if not a little oil sprayed under the rubber covers may free them.

Mine chokes out after the initial start, and will not run in any position except the off position.

what all have you done

to the carbs. Have you cleaned them and now you are experiencing the choke problem? I would suggest you go back and do the carb cleaning 101 in detail. redo the idle mixture settings and synching of the carbs. It is sounding like you have and idle circuit problem and going back through the cleaning process and initial settings may resolve your issues.

by the way

what kind of condition is your bike in overall. I noticed by your signature you have an LG.

Rich

Couple things to look for when you pull the bowls off. The brass tube has a small hole in it just above the level of the bowl mating surface. Make sure those are clean. Second thing is if you look at the carb body closely you'll see a little diagonal hole drilled from the mating surface into the lower chamber. The enrichement pick up draws it's air through that hole from that lower chamber. Make sure they are all clear. Then you'll see that that hole connects to a round hole beside the brass pick up tube. Make sure your gaskets have that little hole knocked out to allow that passage to breath.

If all that everyone has said above is right, clean and open then check the size of your pilot jets. Too large a pilot will make you run rich on choke (enrichment).

Ok guys. I am going to pull the carbs off again to look at things. Don't know if i will find the problem, as i have had the carbs off about 8 times in the last year. This has not been a problem up until lately, so maybe i got something plugged. I am coming real close to parting her out. I have my cbr1000 that i like just as much, and it gets better mileage. I still get 38 miles per gallon on the XS, so it does ok after idle. I will try to find something that will describe the choke, and idle circuit in more detail.

When you get it apart look at the seal made into the plunger. I left some in a dip bath too long once and it ate those seals up.

Don't

part it out till you give it a chance. If you hit a brick wall, send me your carbs and I'll look through them. I can generally find the issue if I can get hands on. These are wonderful bikes, I won't charge you a cent other than the shipping!

[mack]

If your

interested. I have a set of carbs here that are from and 81 LH. Pristine inside and out. Not sure how your gold looks but if you send me your carbs, I'll trade tops and turn these around real quick so you can ride ASAP.
