I agree. The carbs need to be synced with a vacuum guage. If your float levels are too high even by 2 mm, it will run rich.

The bike should idle at 1000 rpm.

Everything you describe is un ballanced carbs, You are close to running well!

Yes, sounds like you just have to dial it in now! Syncing those carbs will have a huge improvement in your bottom end & the knock should be gone!
