I have a 2007 gs500f when I got it it had been sitting a while so I pulled and flushed tank and pulled and cleaned carbs put in new plugs and got it back together after a few problems with float bowl seals it's back together started it and it had hanging idle around 4500 so of course I tried to adjust with the idle screw it would adjust a little but once it got down to 2000 it started to slowly die off until it finally died then i noticed smoke coming out the tail pipe was white and had oil coming out air box breather not a lot but still can anyone help me
Hanging idle, too much air = vacuum leak. I forget what white smoke indicates, but I think it is a lean condition. Someone with more experience can verify that. Only adjust the idle screw once it has warmed up. That screw usually doesn't change much unless you have just purchased the bike and someone has buggered with it. If it was fine before it was sitting, and now it is running poorly, chances are:
Carbs (clogged pilot jet)
Air leak (hose/intake manifold boots/stuck intake valve).
There are instructions on checking for vacuum leaks in the wiki, but ye olde carb fluid test is the usual check. Check and test those and report back.
Cleaning the carb...AND monkeying with the screws.... :nono:
And anothe one bites the dust, another one bites the dust

DON'T MESS WITH YOUR CARBS AND THEY WON'T MESS WITH YOU.
Jack...it's not that cut and dried :nono:
People buy bikes that have been neglected....forcing people to have to dig into the carbs. Yes, you never had to touch them ever in XXX,XXX miles, you obviously ride regularly enough not to have varnish issues.
Nothing's ever cut and dry Steve but I have experienced enough during my riding years to have some opinions contrary to the common tear the carbs apart advice given here so quickly to people new to bikes and to mechanical work in general. If you think I'm leary of messing with carbs I'm not. Went to work in a garage in 1948 at age 15 and first thing the boss handed me was a torn down 2 barrel Buick carb that had been soaking in cleaner all night to put together. The overhead valve V-8 revolution started the next year (49 Olds) with Quadrajets and the like to mess with.
Back to bike business, after a CB400T 1st bike for 6 months I got a CB750k I put 80k miles on and I removed the carbs and opened them up to see what they were like, they really didn't need it. Replaced the 750 with a almost new CM400A I putted around on for 90k miles and parked it when I picked up a Nighthawk 650 that had 10k miles on a 10 year old bike. Rode it for about 50k miles over 3 years never touched the carbs because they didn't need it.
Replaced the Nighthawk with my 97 GS bought new in 99 and riding year around here in NE Ohio I dusted off the old CM400A to use for a winter bike for 3 months a year and it was parked 9 months a year while I rode the new GS that was parked the 3 winter months a year. Never had a carb problem with either bike. Put 80k mile on the 97 GS over 4 1/2 years before it was totalled and replaced by my current 02 GS.
I never prepared any of those bikes for storage, no draining carbs or adding Stabil or whatever, I just parked them. So I'm of a general opinion concerning bike carbs that they don't need torn down and cleaned unless they have jets and passages that are actually plugged up tight, they usually clean up good as new with a tank or two of gas with today's cleaners.
People still inherent, other people's problems and end up having to go into the carbs, it's not just a matter of leaving them alone, that was my point.
