Access to main jet needle for position adjustment

Is there a way of getting at the needle without removing the throttle shaft.

GS1000L
VM26SS carbs
K&N pods x 4
Jetted to #115

Now I need to move the position of the needles to the 5th groove but I can't find a description of how to proceed with the 4 carb setup. I don't want to take apart the carbs if unnecessary. If I have to, I have to.
 
Nope..pull the throttle linkage and remove the screws that hole the slide linkages to the slides.
 
Thanks for the reply Chuck.
I'm not a mechanic by any means so are there any concerns I might have? Damaging seals, needing a re-sync of the carbs, etc?

Do I just remove the mounting bolts of each slide arm and the throttle cable link bolt and the shaft will pull out? Can this all be done in the bike or should the carbs be removed?
 
Might be able to do it on the bike.

Jump the return spring off the pins so there isnt tention on the linkage.
Remove all the top covers.
Back the idle knob out so it isnt touching the linkage.
Remove the 8MM bolts and washers that bolt the slides to the shaft.
Remove the phillips head screw on the left side that holds the lock plate thing in. its between carbs 1 and 2.
Remove the two rubber end caps.
Push on the shaft so you can get the retainer plate thing out.
Push the shaft out one side of the rack.may have to wiggle the slide linkages so it will slide out..they tend to jam now and then.
Remove a slide and do the switch....note there is a hole in the metal plate under the slide linkage with a hole in it that lines up with the hole in the slide.
When reassembling be sure the holes line up in the plate with the ones in the sldie..two screw holes and one air bypass hole.
 
yeah..but if you didnt want to remove them from the bike I was just sayin. Everythings easier on the bench.
 
It's on the bench, and first clip moved. I take it I should remove the main jet before inserting the needle back in so I don't damage the needle or should the needle naturally find the jet hole?
 
Just use your finger down the bore to guide the needle back in. Start the slide and dont jam the tip of the needle into the carb body..just start it and guide the needle home.
 
Tuning for K&N's is so much fun....

Thanks for your help Chuck. I really appreciate it.

That wasn't hard at all. Just needed the confidence to dive in.

Didn't remove the throttle shaft completely. Pushed it over so I could do 2 carbs. They I pushed it the other way through so I could do the other 2 carbs. Used rubber tipped tweezers through the air filter side to guide the needle into the jet hole.

Check the floats for height, play with the pilot air screws a bit and I should have a bike to ride in an hour or so.

Thanks again Chuck.
