I’m at a loss... I have an 81 XS650 Special. I was experiencing a lot of popping out of my exhaust. I was told that cleaning the carbs would probably solve that problem. So, like an idiot, I went for it. After cleaning the carbs, life happened and my bike sat, unassembled, for a year or 2. I finally was able to put the carbs, gas tank, and air filters back on. I went to start the bike, and it sounded like it wanted to start, but just wouldn’t turn over.
My battery is newer, and was on a tender, and my connections are clean; my plugs were pretty new. Then it dawned on me...old gas! I drained my tank, added new gas. I tried getting it started, and eventually I could get it to turn over and run, but only for about 20 seconds, and then it peters out.
So my routine every couple days is, take the battery off the tender, fiddle with the idle screw, get it to run for a few seconds, get mad, shut it off, put the battery back on the tender, repeat.
The other day, my father suggested changing the plugs, so I did. It started right up! 30 seconds later it petered out.
A friend of mine seems to think it the mixture, but I can’t find a picture or a diagram of the location ANYWHERE online. I tried the carburetor thread on this site, but the pics won’t load. There’s no mechanics in my area that will work on a bike as old as mine, and I dont even know how I would get the bike to a mechanic that would be willing to do the work! HELP!!!!!

On the carbs try www.amckayltd.com/carbguide.pdfI have it saved on my computer. So pics load just fine. When you look at the top of the carbs there is a tower that sticks up. Thus tower has a plug in it. Under this plug is the idle mix screw. If you didn't remove this plug and the mix screw under it you didn't get your carbs clean. On the idle mix circuit, the fuel mix from the pilot jet flows through a passage to the mix screw. Part of this fuel mix flows straight to a hole by the throttle plate. Part of this mix flows through the mix screw and comes out the three tiny holes by the throttle plate. When cleaning that passage can't be cleaned out with the mix screw in place. Leo
