HELP! New kid on the block (carb prob)

[DGXSER]

Glad you got them out Ebird!! BTW, if you look through all the tech tips on the mixture screws or carbs and just about any thread theat mentions them here, you will find at least one post or line giving that exact same advice. So your budy is smart if he gave you the same advice as the true geniuses on XS11.

took an engineer genius I know to fabricate a little gizmo to do the job.

I know that removing those screw tips has caused many a headache around here. Can you expound a bit on this little gizmo? A picture or technical drawing, perhaps? Would be nice for future members to know about, assumng it worked as well as you say it did.

yer sure I`ll do my best to describe it. My friend got an alloy rod about 1/4" diameter it was already shaped in a sort of flat "s". He put it in the vice and cut a slot accross the end about 3/8" deep. Then he got some wire which was the right gauge to go into the holes, it may have being oh so slighly bigger but as they would be all the same it wouldn`t matter. Then cut a short length of this wire and forced it into the slot at 90 degree from the alloy bar. Put the thing in the vice and tightened it so the slot closed firmly on the wire. Incidently the wire was only about 3/8"-any longer it would have bent too easy. Using a very small hammer he was able to hold the wire,which he flattened the end on a belt grinder over the broken bits left behind, and struck it with said hammer thus forcing the broken bits out.
Now for something completely different. I am looking for a motorcycle half helmet preferably black, size small.Can anyone help? For some reason they ain`t available in UK.

Puzzled


My carb kits arrived and I set about changing what I thought I needed. Turning upside down and removing the float cover #1 carb has a large jet screw in the middle and a smaller one which was over an even smaller jet. #2, #3, & #4 had the large main jet but only had a plain cover screw over the small jet chamber. Should they all be the same as #1?

[CatatonicBug]

All 4 carbs "should" be identical in that area. It may be that the PO swapped out one of yours for a different year? Pictures would help though, as your discription of "an even smaller jet" doesn't make sense to me. There are only 2 jets in that area. The blank screw in the other 3 may be the plug that was used on some years/models. The main jet was the only way fuel got sucked up in there, and the pilot jet ran off of the main jet. The format of those 3 seem ok from your description. The #1 carb does sound strange though.

[earlybird]

I thought it strange that 1 carb was different. I think it has a main jet, pilot jet which is situated under what I think is called and air screw. Why the other 3 only have a blank over the pilot jet I don`t know. If there are any photos on here somewhere that may help. D

Hey EarlyBird,

Okay, the carbs should look like this:


The screw over the smaller pilot jet should be solid, so if your #1 seems to have a JET type screw with a hole in it allowing fuel to get thru that screw directly to the pilot jet, than it's WRONG, and you should replace it with any solid screw that will fit the threads and seal against the tower!!

beaten

I don`t get beaten very often but I have come to my wits end with these carbs. had them even on the carbtune but it still is a bitch to start and doesn`t want to idle properly. No #1 exhaust pipe is coller than the other 3 after I have had it running, - and now the tube on the TV is going- I can`t win this time.

[earlybird]

Pulling hair out!!!!

I have balanced the carbs, all running even on the meter, but #1 pipe runs cooler than the others. Put it all back together and then it is a bitch to start and then I cant get it to run constantly on idle. I adjust it up and it revs. I adjust it down gradually and then it will simply conk out. What am I doing wrong.? I wish I had never took the carbs off now to clean and service them.

[CatatonicBug]

When you say you adjusted the idle, what do you adjust it TO? Normal idle is around 1100 rpm. It really sounds to me like the jet in the bottom of the float bowl on your #1 carb is clogged. Have you adjusted the mixture screws at all? You might try that, and see where it gets you.

[earlybird]

It idles very lumpy at 1000 rpm. All the jets are new. I have made slight adjustments to the mixture screw. original settings of 1.5 turn out. I have taken them in to about 1 turn out. I have a compression tester coming to see how that side is doing. Apparently the first thing I should of done was to check valve clearances. What do I know I ain`t no mechanic anyway.
