Well, after being down for the last month my fork seals finally arrived and I got the bike all back together today. I started it up, excited about going for my first real ride since buying it in January. Then I noticed the huge pool of gas under the engine. Getting huger by the second too :(

It turned out to be coming from the right-most carb's overflow tube. Wouldn't stop so I tried the time-honored technique of bashing the carb with a rubber mallet. That changed it from a steady gushing flow of gas to an intermittent gushing flow of gas. I'g guessing the float or float needle got stuck during the downtime. Was ok before. Does anyone have any ideas for making the carb go back to normal without taking them off? Not looking forward to that job though I suppose that's gonna be next :(

Re: gusher

For the 1 and 4 carbs, it is possible to place a piece of mirror underneath the carb and with a flashlight, see the four screws holding the float bowl. A short phillips screwdriver and you can remove the bowl on #4. It isnt easy, but it can be done. I would try placing a shallow tub or just some rags under the carb and drain the float bowl a couple of times to see if any dirt or whatever would get flushed out. ( to drain the float bowl, you dont need to remove the bowl. Just remove the drain plug) After that, I would ride it a bit and see if it "fixed itself" :-) sometimes, its nothing more than a tiny piece of debris causing the problem. If it still doesnt work correctly, then taking off the carbs, and checking float level and float needle operation is about all you can do.

Take the float bowl drain screw out and drain the gas and then refill it several time this may be enough to wash the dirt out of the carb. Didn't see what year your bike is 1980 newer The O ring on the float seat could have dried up. If they haven't been replaced take the carbs out and change them
 
That's a good idea. Certainly worth a try. Now to find a screwdriver that fits the drain plug. It does seem like a piece of dirt could have gotten in there. Will let you know what happens!

So is the left side #1? I can never remember...

Left is 1, and right is 4.

If dirty gas is a problem, add see through fuel filter. If it gets a lot of debris in it get the tank cleaned and coated.
 
IT WORKED!!!! :D I had to drain the gas three or four times to get the dirt flushed out but it quit gushing and is back to normal now. I spent some time test riding this afternoon and she seems to run quite well. I suppose if it wasn't such a PITA I'd take the carbs off and clean them since I did get some dirt out. But for now I think I'll just run it and see what happens. Thanks guys.

Now to fix the throttle cables. It idles at 2000 rpm when warm and can't be adjusted. Looks like the PO screwed up the cable adjustment (it has the dual cable setup). That can be next weekend's project...
