I have a 2000 GS500 am having some small problems. I figure I'd ask what anybody thinks before trying to fix it.
The other day I was riding and hit a big bump. Seemingly after that, my bike started to run differently. When I start it, even after warming it up for a while, it stals when it idles (it now idles around or below 1 RPM). If I set the choke properly, it fixes this but I shouldn't have to do that. It also doesn't seem to pick up as well. There are no fluids leaking and everything seems to look alright. I'm thinking maybe I just have to reset the idle RPM but I want to see what anyone else thought before doing this.
Get the bike nice and warm (i.e.: 15 minute ride) and set the idle to 1200-1300rpm. Kerry picture to follow.

"Kerry picture to follow."
Got the pic, but what should I do aftr warm it up and seting the idle. Also, what are the other items (not idle adjust screw) highlighted for.
I adjusted the idle to around the proper 1.25 in a sort of stuttering/puttering way. However, when I put the choke on it jumps to 5. I didn't get a chance to ride it yet so I'm not sure how the adjustment impacted the overall feel.
O.k., what we did is set the idle so we can eliminate that as a problem. So far, your bike should be fine; even with the 5k rpm with the choke on. Actually, you should back off the choke a little at a time to keep it between 3k to 4k, on warm-up. How does the bike run, otherwise?
1 RPM how can you run it that slow lol i run mine at 1,500 rpm im going to take a wild guess here but could float height be part of the problem?
I don't see how a bump is going to adjust the tangs on the floats, unless the floatbowls where empty. Unless, you're infering they were off before that?
I vote that some debris got jostled loose, floated or flowed, and got stuck in one of the needle seats. Open the floatbowl drainscrews and set the petcock to Prime, for a few seconds and flush the contaminants out of the floatbowl.
So I drained the floatbowls for a few seconds. I also adjusted the air fuel mixture screw after reading through some previous posted topics. The bike would stall when I would come to a quick stop and kind of not want to take off when I gave it gas.
However, after making the adjustments stated above, it seems to be running fine again. I'd like to that everyone who has helped. If I come across any more problems, I will be sure to post.
