Won't start.

[iceman831]

I just got done going through my Mikuni BS34 carbs on my 1982 GS1100GLZ. I got it to fire over once and even start and run for a little bit. Rough but running....It seems like the floats are too low and no fuel is being drawn to the jets. I set them at 22.4MM or .882 inches that I saw in the carb tech thread. Now the bike will not even fire over. If I spray carb cleaner in it will fire
Fustrated...Any suggestions?

You went through them.....what do you mean ? Do you mean, dipped, compressed air blown through and new orings ? You know, the recommended carb cleaning ritual .....

Do you have good spark ? Have you adjusted the valves yet ?

Hi Mr. iceman831,

I think the main questions right now should be; Did you follow the carb cleaning bible religiously? Did you bench sync the carbs? Did you put the airbox back on? Are there absolutely no leaks in the air intake system (i.e. new boots, o-rings, airbox sealed)? Let me roll out the welcome mat for you. Pay particular attention to the "Top 10 Common Issues".

I can't really add much to what has bee suggested but, did it run before you 'cleaned' the carbs?

[iceman831]

Carbs

Yes i went through them well cleaned and all passesges blown out jets cleaned with an ultrasonic cleaner

[reddirtrider]

Carb cleaner will burn easier than gasoline. You might want to check for air leaks and a good spark. Measure the voltage at the coils - did you change plugs?

[iceman831]

It ran...had a little stumble at quarter throttle between 2500-3500 RPM The bike had sat for a long time prior to my owning it

Plugs are relativly new have about 1400 miles on them
