That is your idle mixture screw settings. Follow the link in my signature to set them correctly.

How did you clean the carbs , complete tear down and dip or just spray with carb cleaner? New o-Rings?

How were the leaky boots repaired?

[DogGreen]

The intake boots were repaired with a chemical thats used to repair windshields

[DogGreen]

tore them down and sprayed then air to clean out the passages

Do it right, or do it again and again and again. Dip the carburetors, and go from there.

Learning to put your thoughts in a written format that other people can understand would help too.

Greetings and Salutations!!

Hi Mr. DogGreen,

Welcome to the forum.

Click the link in my signature file and go to my website. Then click on the READ ME page. There you will find a couple of maintenance lists. These tasks must be properly performed in order to have a safe and reliable motorcycle. On my website you will find "how to" guides that show the proper way to clean/rebuild the carbs, repair the intake system (NEW intake boots and O-rings), repair the charging system, brakes, etc. You may even find a manual to download and a list of vendors where we buy parts.

Taking any maintenance shortcuts will be frustrating at least and dangerous at worst. Do it right the first time.

Thank you for your indulgence,

BassCliff

If you want to keep loving this bike, follow the required maintenance tips , so head to Basscliff's site for required reading. Little tiny passages are hard to clean without complete teardown and dipping in solvent- clogs here will drive you crazy with idle frustation. The goop on boots might work for a while, but likely disintergrate with engine heat. On each carb,there is an o-ring at carb boot/ head interface- after 30 years, it likely isn't sealing and will cause air leaks.All these things will drive you crazy if you don't address them properly.
