Can I get to the needles on my CV carbs without using a saw?

And why does this forum omit words like "how" "do", and "I" from my search? Seriously, my search should return less than 40 pages of results.

No complaints until you have struggled for days! But someone learned will explain these details. What bike are we preparing to torture and why?

79GS1000. You may remember me as Burp Reynolds. I used to pester you guys all the time, but my profile got deleted when I didn't have any problems for a couple years. I need to ditch my airbox or I'll spend all my time working on my Puchs instead of my GS, which needs the work a lot worse. My neighbors have convinced me that I can run pods at this elevation without rejetting due to the lack of oxygen at 7,000ft. I know everybody on this forum has a tattoo on their back that says otherwise, but all of my neighbors have done it, so I figured I'd give it a try.

NOTE TO THE GS'ers THAT HAVE READ THE FIRST COUPLE LINES OF MY POST AND ARE ABOUT TO REPLY WITH A DETAILED EXPLANATION OF WHY IT'S IMPORTANT TO REJET AFTER EVERY MOD, HACK, OR CHANGE IN RIDER WEIGHT OR STYLE: If raising the needles doesn't help, I swear I'll get a jet kit with my next check.
 
CV carbs on a 79 GS 1000???? I have the factory service manual and for both the SL and SN models it calls for VM26SS carbs......

I remember Burt Reynolds, but very little else! That Texas guy would like a pic of carbs, so we can lecture you regarding your neighbors fixation with pods. Bike ran fine for years, but now the airbox has to go? 7000 ft? Colorado?
 
Hey..i dont need anything. I was just notingb thatb he says he has CV carbs on a 79 1000..that caught my eye as i have the factory service manual and all models call for VMs.. if he has Cvs and it runs then cool. I had never heard of cvs on a 1000!! thats all.

MOST '79 GS1000 bikes do NOT have CV-type carbs, they have VM carbs.

If you do have CV-type carbs, the needles are probably NOT adjustable without some effort.
You have to remove the upper spacer over the circlip and replace it with a thinner stack of washers.

If you have the VM carbs that everybody else got, the needles are easily adjustable by moving the circlip.
Remember that you lower the clip to raise the needle.

Right. I meant VM. Obviously it's been a while since I worked on this rig.

Ok, so, I'm not asking how to raise the needles on carbs, I'm asking how to get to my needles. I can't figure out how to get the sliders out without pulling out the rod that holds them all together. They have these weird adjustable linkages at the top that are in the way of pulling out the sliders.

Do you know how to remove the throttle ( slide) connecting rod..the one all the slides are bolted too?

its way faster and easier to tell you myself.. 248 219 4122..than all it would take to type it out..call me.
 
OK I will type it out

Remove the return spring between carb 2 and 3.

Remove both black rubber end caps off the carbs.

Remove all the carb top covers.

On one end of the slide connecting rod youll see a Phillips screw and a retainer clip..remove the screw and tap the rod a bit to loosen the clip and remove.

Remove the idle screw on the throttle linkage.

Remove the 8 mm bolts out of the slide linkages and the throttle linkage. 5 places.

Remove the rod starting from the end the retainer clip was at. You may have to tap it thru till you can grip and remove it from the carbs..use pull and twist motions.

Remove the slide from the carb body.

Look down in the tops and remove the two small screws.

Lift off the linkage and then remove the needles.

Reverse the process to reassemble. NOTE Thers a groove in the slides that corresponds with a tang in the slide tower. Line them up being gently to get them back in. And be sure the needles go back in the jets without jamming. Do this process slowly and easily !!! Put a thin coat of your favorite grease on the connecting rod when you get ready to reinstall it. Line up the holes in the rod with the holes in the slide hinges and reassemble them..

VMs don't need a jet kit, you can replace any part you want

Why do you need to get rid of your airbox?

Oh
my
god.

That is what you have to go through to raise the needle? And then you have to sync them after each time, I assume.

You have got to be kidding me. That's what I was afraid of, but was WAY too optimistic to admit to myself.

Well, thanks, guys. BTW, This is why I always wrench on my nice, SANE single cylinder puchs, and never work on my trusty old GS. I'm going to go overhaul my magnum in under forty minutes and see if that makes me feel better.

I've had to enlist the help of a neighbor to get my airbox off one too many times. I'm way behind on a lot of work that needs to be done to Methuselah, and I've been procrastinating for like two years because that box is in the way. Besides, I routinely derestrict every engine I get my hands on. It's just Nature's Way.
 
yup..thats what it takes to get a slide out.. thats only about less than 1/4 of total disassembly!!!

No less than 1/4 of just the carbs..If you set the carbs in front of you and read the steps one by one..youll see its really nothing. Do them in order and in about 15 minutes tops youll be done and ready to repair whatever the issue is..
