So after fixing the fuel line and pet chicken disaster that the poor gs was having I have a question about the way the bike runs. It runs better now but still hesitates . I would think that at around 6 or 7K rpms the bike would really get up and go. I am noticing a hesitation in this area.
After looking at the carbs it looks like both fuel screws are missing:( . I am not sure how it was running anyway with the fuel lines all messed up and no fuel screws. :guns:
This would make me think that the bike is now running very rich, even in the cold weather. Does the bogging and missing the punch sound like it could be caused by the lack of fuel screws. The more I think about that not only is it rich but that is also a air leak in the system. :o
What do you guys think of a gs with no fuel screws :dunno:
You're talking about the mixture screws, right? If they are gone, you'd be sucking air through the holes and leaking gas out of them; should be nice and wet around them, unless the vacuum is so great it sucks the gas up with the air (I would hope) and the float level is low enough to not leak gas out the hole (sweet).
Hesitation at 6-7k means the needle is set too lean (low in the slide, clip too high/not enough washers under the needle).

correct
I have a 2002 so slightly different carbs but maybe you cant find it because the screw is still covered up with a brass fitting or something to prevent tampering with the mixture. Unless you or someone has removed the cap then it will still be there.
Also my screw is recessed way up in a hole and i use a screwdriver bit to adjust them without having to take off the carbs.
Just a thought

Good tip on the screw driver bit. I will verify for sure if they are in there or not tonight and let you guys know. I would really like to get the bike running better. I may also try a #4 washer from lowes under the needle to richen her up a bit to help give the power back.
Well I got a mirror and looked under the carbs and sure enough the fuel screws were there. Glad I double checked. They were at 1 1/2 twists out. I moved them to 3 per the suggestions I have seen here and now just need to ride it.
I also picked up some #4 washers for the needle. I will see how it runs with the mix screws backed out some more then put the washers in if it is still sputtering up top.
Thanks for the tips
If you have stock mains ... go up 1 size on them as well ... needle is more 4-6K under load ... over that Mains are more effective ...
Cool.
