Sorry, bad use of words... I meant, you're not through playing with the jetting by a long shot. Fine tuning is where it's at and it's a step by step, time consuming process.

The instructions give you basic starting points on where to start, but each bike differs and setting it up for your riding and location makes it close to perfection.

Yes, the mixture screws should be set anywhere from 1-3 turns out when you're all done, but for troubleshooting/fine tuning purposes, turning it out more can lead you in the right direction. You don't want it backed off so much that the screw can fall out, but anything less is fair game for now.

Are you using the "blip" method to set the mixture screws?

I use the "alternate" method.
