Appreciate the info! I’ve run into a different issue now. Not sure if it’s carb related or a little more serious. I had the bike idling and pulled the plugs to make sure all the cylinders were running ok and the 3rd cylinder was not firing. Really bummed about it as I was getting the bike close to road worthy. I removed the spark plugs and took photos. What should my next step be and what are your thoughts on the plugs? Thanks!!

Oh ok, I feel like I’ve got those adjusted fine at this point. What would be the reason for the bike wanting to stall when I open the throttle too quickly? Should I turn the air screws clockwise to fix that issue? thanks again for the help!

I’ve made some progress but it’s not 100% yet. I’ve got it idling at 1,100rpm and sounding smooth. Only issue is when I give it throttle too fast it bogs, when I give it throttle smoothly no issues. I’ve changed the exhaust gaskets, synced the carbs and turned the air screws at 1 3/4 out from lightly seated. any ideas why Im getting the bog?

I’ll make all adjustments with no choke. Does anyone have any pictures of roughly where the throttle adjustment screw should be? Or measurements by any chance Thanks!

Thanks BigT. When you say tune to high idle with air screws would I be turning them out more than the recommended 1 1/2 turns? I don’t want the bike to run lean I just read that 2 turns out was a good starting point, I’ll try the 1 1/2 turns that you recommend. should the throttle adjusting screws be at a specific setting? I feel like that’s when the bike started to run like shit, when I started messing with those settings. Now Im backpedaling trying to get the bike back to stock settings as it was running pretty well Lastly, Should the choke be off while making all these adjustments?

When I was “syncing” the carbs I had the idle at about 2,000rpm and once I had the gauges (vacuum) roughly at the same level I tried to lower the rpm to 1,000 and the bike would just stall. what I’ve done since is try to reset the throttle adjusting screws equally and turn the air screws 2 turns out but I’m still having issues when I lower the idle to 1,000rpm. Should I be turning the throttle screw to a certain position? is there an order of adjustments? I really appreciate the help

Im using a carb tube pro. when I raise the idle and sync the gauges it seems ok but once I lower the idle, everything goes out of wack

Hi Folks, I picked up a “barn” find GS1000 that I’ve been working on these past few weeks. It was more a cosmetic restoration as the engine was running smoothly….running smooth until I touched it of course. Im hoping to get the bike on the road before the season is up and was working on getting the carbs synced. I started playing around with the throttle valve adjusting screw and now the bike barely idles. Does anyone know how to bring that setting back to stock? Like I said bike was running pretty smooth before I touched it. P.S. I’ll add some photos of the bike on another thread. Any help is appreciated! All the best, Carlos
