Take a deep breath, and remember that it wasn't a rocket scientist that designed the flipping things. If your bike is reliably running from stop light to stop light without either dying on you, or spitting out plumes of black smoke, then you're not that far off. At this point, you're only refining and fine-tuning, so you can afford to take your time. It took me almost 4 months of off-and-on, back-and-forth tuning, before I got the things were I thought they were decently tuned, and even then the stupid things still could pull a "black magic" on me. Give a yell if you need any advice balancing them, that's fun too.
