Do I need Dyno?

[mjvielle_imp]

I've had it done to many bikes in the past. Yes, you can feel it. Without a PCV I don't think you can change much. If I lived in America I would have done it already
Unless you do track days or pick fights on the street, stock is fine.

What do you mean, "If I lived in America, I'd have done it already?"

thks!
