Idle should be set around 1200, but if it's not running right, you're not going to be able to "get it set" just yet.

How do your spark plugs look?
Did you properly set your pilot screws after you cleaned the carbs?
Did the bike run properly before you cleaned them?
How did you clean them, did you remove all jets, pilot screws, etc.?

Demon, I think he's saying it's now running smooth, issue resolved, with the plug replacement.
