Thats it im torching my xs!!!

[dezmitchell]

Ok so tell us a bit more info. What yr bike and earlier or later carbs. Do you know the jet sizes, how many turns out on the mixture screws, pods or airbox, stock pipes etc. Give us something to think about here so we can offer up suggestions.

bike is a 1980 xs 1100 no special just regular model

Jet size is 137.5 for mains everything is stock i think the air screw is 2 turns (i belive ....im thinkin back to fall) the bike has stock air box and straight pipes ...How ever i have pods i want to put on and harley mufflers.

137.5 seems TOO BIG for an '80! Some of the early '80's had the early carbs, and that would be close. You should have 115 if you have the later carbs!
I'm sure the folks up there can help you out, just need that second set of eyes sometimes. Relax, and help will be there soon!

[dezmitchell]

thats just me trying to think back i would have to go back and tear the dam carbs out and have a look .....

Guys,
It's been a long, long day for me... This has perked me up!
Dez.... your post almost has me rolling on the floor... laughing my ass off....
I'm from Dallas but.. in San Antonio, TX right now working on a new hospital that's going up at Fort Sam Houston....

Anyhow.... just wanted to shoot you a note of encouragement... and let you know that even though your issue is frustrating ... you'll get it figured out and will learn something.... Everyday I learn something .. makes it a good day.... and
you're irriations and comments are completely understood and speak loud and clear how I feel at times.... and everyone else that's posted on this one has brightened my day... and I'm sure they all have felt the same frustrations....

In particular... I love your thoughts.... and how you plan to murder your bike..... by tieing her between your truck and an immovable object.... and pull it apart (probably very slowly... and you probably imagine there might be some moaning and screaming as all well).

I've learned that I must speak sweatly and softly to my sweetheart.... stroke her softly as I throw my leg over her seat and gently sit down.... stroke her tank as I reach down to flip on her fuel.... all the while promising to be sweat and ride her easy..... all of this seems to somehow work as she's never given me too much trouble.... other than her brakes.

If it's pig rich it's a carb issue... (apparently) however, (past experience) I was looking at one of these bikes about 10 years ago... guy wanted $1,500 for it.... but it didn't run right at low rpms .... and he didn't know what the issue was and neither did I. I took it to a bike shop to have it looked over before making a decision (spent a hundred bucks or so) (btw yamaha wouldn't touch it because of the age... pissed me off)... it acted like it was running pig rich at low rpm... the dude at the bike shop told me it was the computer (ignition module).... no longer available and he thought he could fuge an ignition module from another bike but... no guarantees so, I passed.... however, until this bike got up to speed... it only ran on two cylinders (i.e. spark was dead on two cylinders) but once it got to a certain rpm everything would kick in and then it would cut loose like a drag bike....
Obviously there's no way to know from the info so far what's occuring w/ yours... really wish you were closer .... would love to take on the challenge.
Hang in there dude... there's way to much help on this forum to give up and put a bullet in her..... she may be broken now but she can be fixed..... don't do it yet...!!!!

Yup i also think the later carbs with 137.5's are way too big. I have later carbs on the 81 with 120 mains in it and it seems a bit rich. trdiver71 and myself were just chatting about the orings on the needle valves too. Straight pipes are hard as hell to tune for as well. Is it fouling at higher revs or at idle? Are the plugs dark brown or black? What are the floats set at cause if it is jetted like the earlier carbs it may well be the floats are set that way too.

I also happen to have a 4R0 TCI if needed, so we can eliminate that by switching it out.

I dont know what that is ?? I just got back from the garage and im running 115's ....I also have 125's sitting in my tool box for some reason .......as far as the plugs there black at all rpms .....

Ever get that feeling of Dejavous!!

I will presume my demented computer is acting up again

AH F**K it for the night im off to get laid ...my xs can wait until tomorrow to suffer its fate

thanks for the help guys i will be back tomorrow

[cywelchjr]

Straight pipes are almost impossible to tune for. You need SOME back pressure at least to be able to tune the bike. Several have tried and found that some sort of muffler was needed on the exhaust system to make the system able to be tuned. You would probably need to change not only jetting, but cam profile and everything to get these engines to work with no back pressure.

I have an 80G, late style carbs, and the mains are 110 straight across. The plugs run white-ish, so 115's would be a good place to start, IMO. CZ

[Rasputin]

I goofed the 4R0 TCI is off the 81's, so it will not work on that 80 model without changing other parts that I do not have here. The TCI is the brains or computer which controls the spark among other things.

glad to hear you got your mind off the bike last night...

I want to suggest you forget about the carbs and jets and such until you do something about the straight pipes and pods - I think if you spend time and effort getting it right now, you will have to double your effort when the mufflers are on. JAT


Glad there is help closer than me!

Well i still haven't figured out my bike ....

Hi Dez,
well fukkit, it's taken 2 pages of posts to find out you are in Vegreville AB and your bike is a 1980 Standard.
If you'd put up a signature line we'd know this from the get-go, eh?
OK then, has the bike always run like sh*t since you've owned it or did it go like that later and if so, was it right after you did something to it?
