After putting it off for months, I finaly broke down and started working on my 93 gs500.
It had sat for almost a year after the first owner had there first big spill on it ans sold it to me for cheap.
I had to replace the rear brake line and re-weld the exaust.
Then I did a full tune up...till I got to the carbs.
It would start and run on full choke, but then die after you cut the choke.
Sounded like the idel jets to me.
After I did some closer looking, i found that the right side carb had almost half the idel jet missing.
Thats right, missing.....
I used a drill bit and a hand crank from my tap and dye set to remove it just past the rest of the theraded part.
I then removed the rest of the jet with a pick and replaced it.
Now that my long winded rant is done, on to the problem...umm...the other one I guess.
Thebike runs and idles, I even rode it around the block a few times.
Some times when you grab the clutch or just start it after its warmed up, its like the gas stuck.
It reves up to around 6-7k.
The slides are all the way down and the butterfly vavles are closed.
Any ideas?

die set

maybe too big of a pilot. what size did you replace the broken one with?

When you squeeze the clutch and it revs, is it all the time or just taking it around the block? It's physically impossible to run around 7 grand if the slide is down - i would say your clutch cable is routed too close to your throttle cable (or pushing on it somewhere)

I think a 37.5

Its when ever its warm.
The throttle and clutch cables are inclosed and are not toucing in an way.
Its reving at or around 7k.

something is not right here. closed butterfly, closed choke, 37.5 pilots stock mains, and running 7k......

Well, if you think about it, your clutch and throttle should never affect each other. And if the engine is revving, they are affecting each other.

Since the clutch basket isnt near the carbs, the only place they intersect is the cables. So pulling the clutch lever is pulling your throttle cable somehow.

It does rev up when you squeeze the clutch and the tranny is in neutral, right?

Forgot to add: if it was a problem only when the bike warmed up and the tranny was in neutral or between gears, then it would be an air leak around the manifolds.

The cables are not touching in any way.
it dose not rev high all the time or every time.
just sometimes...
if I can, Ill post a video tommarow.

Big Rich scores again.  Search for "hanging idle".

Not necessarily. I've had this happen, but can't remember when or what bike it was.  Leaving the clutch engaged (handle not pulled in) kept a load on the bike so RPMs stayed normal.  But when you pull in the clutch, the engine has no resistance and whatever was wrong with it was causing it to increase RPMS.
