One step Forward.....THEN

OK, I see that number now. Honestly, I never noticed it before. I don't think it means the bowls are different. I'm not sure what you mean by 2nd and 3rd stages. I can explain more about how your pilot circuit operates. It sounds like yours may be plugged in the carb that won't idle and kicks in later at higher RPMs. If you look at my last pic, the pilot inlet (labeled in yellow) is where the pilot jet flows it's fuel/air mix into the carb body. It goes through the body and into the main bore where it can then be sucked into the engine and burned. It exits the body into the main bore through these 4 tiny holes .....

You have to make sure these are clear. Dribble some WD40 or carb cleaner in the pilot inlet, then blow it through with compressed air. Watch for it to come out the 4 holes in the main bore.

So I'm quite interested in this. Took some time to thoroughly clean my what have you have outlined in some of your last posts 5. I used carb cleaner and air. Would you say that the butterfly valves should be closing just enough to cover all three of these holes? It looks like on mine they are covering most of them but maybe not all. I'm thinking I might need to adjust my butterflies and have them close more.

See attached - Thanks

The opening on the butterfly plate is what controls your idle speed. The more open they are, the faster it will be. This is what adjusting your idle speed screw is doing. It's opening or closing the butterfly plates more. The openings on the butterfly plates are also what control carb sync. If your carbs are in sync, the openings should match. If one plate is open more or less than the other, your carbs are out of sync. You can check and adjust this while you have the carbs off. This is called a "bench sync".

Ok, thanks! And this is what I have done by shinning light through the opening and measuring by slipping various size pieces of construction paper in and out of that same opening.

Yes, that's one way, but I do it differently. Yes, I rely on the light shining through to check the openings, but I use no sort of "feeler gauge" or spacer. I simply back the idle speed adjuster screw way off so the plates close completely. Well, they will if the carbs are in sync. If they're not, one plate will be closed and the other still open a bit. Then I simply adjust the sync screw on the linkage between the carbs until both plates are closed completely and I see no light. Simple, easy way to do it, easier than trying to measure a tiny cracked open plate I think.

I had written a description of the events that occur in the transition from idle through the initial butterfly valve openings, and stuck this in my albums. Unfortunately, much of that was lost in the forum software upgrade.

But, that's just trivia FYI. So, follow 5Twins carb procedures.

SHE IS RUNNING!

At first it was only idling on one cyl and intermittently popping on the other side, I kept after it and opened up the Idle jet some more and as the bike warmed up, the other cylinder started running a bit better, it also would die when I gave it throttle, so I slowly feathered the RPMs up and it was like it just all at once opened up.
and both cylinders were running and idling. It still has a bit of gunk in it somewhere because it is a bit troublesome when cold , I have fresh fuel in it with fuel stabilizer, and fairly heavy dose of Seafoam. I will let it sit for a couple days and run it up to warm again, I think it is doing pretty well considering it has pretty much been setting since about 2003. The left carb is the one that is popping a bit when it is cold so there is still a bit of gunk someplace, Seafoam do your work!
But one thing is for sure I don't think I would have gotten this far without your help.
When it was warm and running it was idling at about 1300 rpm and had very good response from the throttle, absolutely drive-able as she is!!!!
I took a Video of it but it is on High 8 tape, I have to figure out how to get it digital!
I want to sincerely thank you guys for accepting me into the fold here as a new member. One thing is for sure, That xs will never be in this condition again!

Congrats Orion61 !!

You were a great help, now on to my bars. I started another thread here for it.

Congrats! Been reading this thread over the past week...and happy to hear it's going!

But, err.... "High 8 Tape"? Is that also from 2003?

"But, err.... "High 8 Tape"? Is that also from 2003? "
LOL yes it is, but it really has amazing picture quality. Unlike Digital colors don't layer like Digital, For instance Black, you see
waves of color like Fish scales.. Plus there is a setting that is Digital, It codes it digitally, It has to run the tape at a higher speed but the colors are richer.
I really like it...Then again I still have a Marantz/Pioneer home Stereo system with an Akai Reel to Reel. My grown Son was about 30 when he gave me a little grief but I challenged him by recording a song from a cd then started them both, he had his back turned and he could not tell the difference which was which...
I do have a Pioneer cd player too....AND turntable, I also have a Quadraphonic decoder with it..It is called Surround sound today, but runs 5 speaker instead of 4.
Funny I was just thinking of that today...SPOOKY!! I have a couple different threads going now with some pictures of it after been untouched in storage for 12 or 13 years....

That's really cool! I enjoy that high-end audio from back in the day, as well as traditional film...I still use my Nixon 35mm SLR on a regular basis...something about having to be precise with setting that I like.

Yep I just quit using my Nikon 35mm myself, I got a used Nikon D70s and it has all the manual control.
As far as the old Stereo gear, I have another full set of Marantz equipment it all powers up but needs work that needs another good home. reel to reel as well.

I had an NAD receiver back when I lived on the East Coast, had saved for it all summer and finally was able to purchase it and a sweet set of Boston Acoustic Speakers (It's all I could afford at the time). For whatever reason I left it when I moved back West... STUPID. The quality of sound it made was something I haven't heard out of anything I have bought since...granted, I'm a cheap bastard now...so I haven't spent that kind of $. Ha ha. New audio technology has gotten so good now it's incredible...but back in the day, it made a HUGE difference to have a quality system. I like Marantz...and wonder how it compares to my NAD from back in the day?
