Float level was correct around 13mm.

It rather seems the opposite....engine runs lumpy, boggy, rich from 1500-2000.

First, let me correct the fuel hose routing, then check everything again.

Who rides this thing between 1500 and 2000. I set it to idle @1700. 3k minimum.
Rich @1500 but OK @ idle ?
Cool.
Buddha.

Well, sometimes rpm is in that range:

1. warm-up. lowering choke
2. traffic

Yes, it idles well since idle is set below 1500 according to spec. Engine gets boggy, I think that is rich, and misfires somewhere between 1500-2000. At least now I know how to reproduce.

Yeah...never ride below 3000 rpm.  Just slip the clutch up to that point.  I thought you were talking about misfires with the clutch pulled in or revving slowly in neutral.

I live near DC Metro with plenty of traffic. It's common to barely crack the throttle above idle (1500-2000) slipping clutch creeping along in traffic.

One of the float needles is also worn. I'll replace both, correctly route the petcock hoses, then I'm hoping it's just a matter of playing with the mixture screws.

Well, at least now I can confirm it's not parts hitting and can just ride the bike without as much fear until I continue working to fix.

How do you slip the clutch at just 1500-2000 rpm?  I'd like to see that...

Just barely crack throttle, hold it there and slip clutch/adjust throttle as needed  . If it matters, I often skip downshifting to 1st when stopped and start in 2nd gear.

I love playing the "don't put foot down" game in traffic.

I'm afraid you might be bogging the engine doing this.  At the very least, you are making it a lot harder on yourself by not revving a little more and downshifting to 1st.  1st will allow you more control of your speed at a low speed, and a few extra revs can actually have a gyroscopic stabalizing effect to keep you upright and stable.

Yeah, there are so many factors all depends on speed. When stopped at light I often start in 2nd...hate that shift from 1st. In heavy traffic, I use 1st.

PROBLEM SOLVED!!

Work done:
1. replaced float needles
2. re-routed petcock hoses
3. replaced rubber cap
4. replaced a top diaphram (slightly deformed)
5. turned mixture screws out another 1/4 to 1/2 turn. This is probably what did the trick.

Thanks.

Awesome!

I've been thinking about slipping the clutch at those low Rpms you mentioned.  I've found that while it doesn't come up very often, there are some situations where I do slip the clutch at around 2k rpm.  I never start in 2nd though.  I don't want to make it harder on myself to control the bike without bogging the engine.

Wrong thread, turns out it was a problem with carbs not engine LOL

The torque of the 2002 model makes it easy to start moving around 2k.

I've owned a 1994, two 95s and never had a gs500 idle as consistently.

Yeah, it turns Budda, BBoy, and myself we all on point with the lean misfire diagnosis.  Is there a patting yourself on the back emoticon?

Love it when a thread comes together!
