:mad:ok evryone , i have had enough ,
i have ried everything to get this bike to run , now i know im not a motorcyle mech but i can read and fairly understand the measurements and ideas of setting rtimming. floats adj carbs ,
the issue of bike that will run but runs out of fuel but yet , the floats overrun when sitting i donot understand!!!
either i run the bike to a professional at a rate of 70 hr which i understand,, but he said may take as much as the bike is worth to fix it ,
i allready have what i think the bikes is worth just in parts beside the original purchase, so i think the bike will either go to ebay. or the junk yard a loss is a loss :(
 
Plenty of forum members in Illinois.
Perhaps several of them could help?

i printed them out me another guy went thru the carbs and relooked at timming and the valves we can get the bike to run but have to put hand over the carb other wise it dies, running the choke doesnt help ,
i thought the float was then to low , so reset them higher , fuel really came out them , so reset them again using a nurse bottle to reflect a tank , no over flow! yeah got it !! NOPE WRONG , put them on and look they leak out the back DANG IT you can get fired up like that go to 4000 rpm then it will immediatly drop down and die , unless you run youre hand over the carbs, ?
i know i have 1 diaphram not working , that s not the problem here, ,
its fuel delivery, or lack thereof,,
but its unbelievable that i cannot find its happy place

You have the airbox in place on the engine? That's kind of how they run without the airbox.
 
i'll do that soon as i eat my sandwich an get back in the garage ,, let ya know what i get thank you trying to stay positive
 
Ummmm... what bike are you trying to fix?

As Tkent says, these will NOT run without the airbox, or with any air leaks.

82 850 gs didnt knowq they wouldnt run without air box?

Please forgive me in advance but there are a bazillon threads on the forum about needing the airbox installed before the bike will run right. Please, please, please, help yourself by searching out info on what to do in advance. We'd hate to loose a GS owner just because of a simple problem like this. There are lots of people here to help you but you need to search out the info and do a little homework.

Please check this thread for more info on what to do, and what not to do as well... http://www.thegsresources.com/_forum/showthread.php?t=171846

As noted, the bike will not run without the airbox. The carbs need the vacuum to help draw sufficient fuel to run. No airbox = greatly reduced vacuum. Even very tiny leaks in the intake system will cause issues like hard starting or creeping idle.

There are also a bazillion threads about petcocks and fuel dripping from the airbox. Either your petcock is leaking fuel down the vacuum tap through the #2 carb (in which case it needs to be replaced), or it's allowing fuel to run while no vacuum is applied (in which case it needs to be replaced; unless it's not OEM style) and the needle valves in the carbs can't hold it back or are leaking around the seats.
 
ok guys reset the fuel bowls the way i used to back in my motorcross days nomore fuel runover
also put air box on bike runs but only above 3 grand below it will die,
also backfire out the exhaust on the right side only after decell of throttle,
also doesnt restart unless it is choked more air leaks??
thanks everyone , it does get disheartning ill keep trying !!
i think the carbs need to be adj and async
 
choke is allowing more fuel flow, so it sounds like you are lean. Popping on decel is a symptom of a lean condition.

Your going to have to adjust your mixture screws. Use the highest idle method then sync them.
 
Trying to take short cuts makes the job twice as hard.
1 did you replace the intake boot O rings? & check boots
2 Did you dip the carbs and do a through cleaning
3 Did you rebuild the airbox seals?

answer to #1 yes new
#2 there where diped then taken and sonic cleaned as well
#3 all new seals on air box
used mineral oil before installing my seals ease of install and never put seals in dry.
side note , these carbs where cleaned before,and new kits put in then
i went ahead and put another new kit in because i was undoing what i didnt know as a fact,
the reason was ?? guy supposivly done tune up on bike when some how 2 small scews got into cyl # 1 he fired the bike and it when to knocking ,
long story short he sold bike to my uncle , who took head off found the issue , put new piston in had head redone the shop broke the head ,
he got another head, and the bike has never ran since now.
i beleive my issue is a lean deal, it may be from mix scews, or carb syc,
for some reason the setting of the floats by the book didnt work in this case, why , i dont know, i had to revert back to the way i used to set my dirt bike to keep from flowwing over, , may have to revisit that , but thats not the reason it wont idle below 3 grand,
since i have the bike running, i will recheck the cam gaps see if they have changed , i have a real nice feeler gauge from a transmission that will work great there they will go from #3 all the way up to 15,
im going for 8 on exhaust and 5 intake
as for syc the carbs , and setting them ther is a x bike racer in town who used to race suzuki he said he can set them up if i get the bike close to running correctly,
 
i do have a stupid question,,
there is a vac line runs from the intake' side of # 2 carb up to the vac asst fuel shutoff,, does this line have fuel thats suppose to run thru it,??\
i wouldnt think so, but it does, the book doesnt say anything about fuel running thru it ,, i would think only vac that way fuel run thru the fuel line when vac is present ?/
