Hey Guys & Gals,Need a little help with a starting problem on a 1980 GS550E Purchased bike with carbs dismantled (PO stated bike ran great prior to carb removal just had them off for routine cleaning, he had a large bike collection) got them all cleaned up and assembled but having a starting issue, Bike will start if I remove plugs and spray starter fluid in cylinders and then it runs great has a little bit of a high idle around 1400rpm rides great power band is good will restart thru out the next couple of hours without issues, If I go to restart later in the day or the next day or two I have to use starter fluid again. Have mixture screws set at 2 1/2 turns out. Not sure if it would be a problem with enrichment circuit:?:
 
found a good article and cut away on the Enrichment circuit

im having exactly the same issue. When the bike is running at first does it respond to enrichment lever if it does you know that probably isnt the problem.

already pulled carbs this morning upper siphon tube is clear, all bottom (on bowl) ones or blocked no fluid or air will pass, soaking right now in carb cleaner and then gonna use wire from a bread tie to clean. Oh and it would respond to choke:confused:
 
Dodik said:
hope you figured out your problem. i'll check mine too then.

only problem is finding something strong enough yet small enough to probe that starter jet hole, Article suggest a drill bit...Might have to run to parts store
:D
 
when i was cleaning those passages i took a spring from a pen and just pulled it out a bit it stiff enough to take most of the gunk out also if you spray carb cleaner make sure that hole isnt pointing in your face. i know mine were clean a month ago but just in case something came from the tank/gas ill take a look at mine.

ok let them soak for awhile and took a straight dental pick to them fits perfectly have a little bit of flow now so soaking for awhile more
 
its number one problem of hard cold starts when valves are too tight. i assumed you checked yours already.

nah, it is easier pulling carbs off then messing with valve lash and Enrichment circuit is a more probable cause. If it wouldnt start at all or rolled smoke out of exhaust I would have gone to valves first ;)

Hi Mr. Walter,

Everything starts with clean carbs, well adjusted valves, sealed air intake system, and healthy charging system. If you don't know the history of the bike, or if any of these systems have never been serviced by you, it's a great idea to take care of these things to avoid trouble down the road. Difficult cold starts are a symptom of tight valve clearances. But hard starts can be symptomatic of other issues too. That's why we like to share a couple of maintenance lists to be sure that all of the essentials get covered. You'll find the lists in your "mega-welcome". Here it comes....:eek:

Let me dump a TON if information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

Enrichment circuit was the problem fired right up as soon as I got carbs on WOOT! now I have to readjust air/idle was idling at 2500 rpm at start up
 
Dodik, when you check your circuit again hold a flashlight at bottom of well and look thru top of jet you should be able to see straight down and if there is any debris, think what got most of mine clean was compressed air thru top side of jet, helps to have a reducer on air nozzle
 
i got mine to start as well it was float height for me when i cleaned mine i guess i made two mistakes one i set floats to 24.2 instead of 22.4 and second i measured from the gasket now it starts but will idle too high even with the screw all the way out.
