newb with carb issue

took off the carbs from my 82 550, About to clean everything during the winter break. Is there a rough setting that I can use for the idle mixture screws? and also the carb sync screws? So that when I put back everything, the bike will at least start so I can tune properly later.

 

i believe the rough setting for the mixture screws is 2 1/2 turns out, as for the carb sync screws am not sure , theres good people in here that can help you out better with the settings, but i know for sure that when you set the mixture screws screw them in and dont bottom them out hard before you start to un-screw them out for your rough setting.

 

There is no base setting for the sync screws. If the bike ran fairly well before pulling the carbs then I wouldn't mess with them until I got a carb stick set. If you broke the carbs out of the rack and the setting is lost then set the butterflies with a feeler gauge to .020mm at the bottom when closed.

 

Man, I sure could have used this info this past weekend. I had no idea where to start with mine, but all I knew was that they were WAY off. My neighbor and I decided to adjust the screws until all 4 butterflies would retain a single piece of paper unless you gave it a good tug. Talk about old schooling it. ;-)

 

That was Old School ... nice. Use the round spray tube you get taped to a new can of Carb Cleaner. That works pretty good; too.

Pilot Screw adjustments are 2-1/2 Turns OUT from bottoming-out.
Forget Factory.
Run 'em out to splitting the difference between 3 and 3-1/4. Although an official list hasn't been compiled, yet ... Most of the ColorTuner's are finding that pretty blue color happens in this neighborhood.

If you're a fan of Old School ... you can Sync a 4-Pack with one Vacuum Gauge; too. Look through my old posts for that surprise.

 

Rick, I don't know about others, but I'm not necessarily a fan of old school. It's just that old school has a tendency to not require the purchasing of new tools that I don't have the funds for at the time.

 

i like ricks approach to old school methods, i think most of them are time proven methods and like you said BK there cheap and in-expensive, allthough having a nice brand-new carb stick , shinny colortune and million piece socket set would be very nice.

 

I also used a fine drill bit once since my feeler guages went awol. Someone on here also used bread-bag twisty tie things. Void where prohibited by law. Your mileage may vary. See dealer for details.

 

That's what I originally planned on using, but I couldn't find any, so I just tore up the picture of the YICS tool that I had printed out and used pieces of that.

 

Sacriledge! Tearing up pics of the YICS tool! Do you spit onthe Virgin Mary as well?

 

The tool was already made, didn't need the pic anymore.

 

Thanks everyone for the input, will try it out.

 

It's alive......

After cleaning the carbs and adjusting as was recommended, I just couldn't resist so I tried starting....cranked for a bit (pretty cold outside) then started smoothly and ran real smooth too. Now I can't wait for sping.

 

Thanks for the update. The suspense was killing me!!! What did you use to static adjust the butterflies?

 

A feeler gauge worked good for me.

 

Next time ...

The Red tube that comes with WD-40 and Carb Cleaner makes a pretty good feeler gauge; too. But, if you need something with less diameter ... the shank of a really small Number Drill is a good way to go.
