Typically all you need to adjust is your air screw. Provided your bike is currently jetted properly (elevation, temperature, etc.). Make sure your bike is warm and you have a clean air filter before you make any adjustments. Any aftermarket pipe flows much better than a stock pipe, so the result is a slightly lean or slightly rich condition. Adjust slowly either way as you ride-test different parts of your bikes power. Bluish-white smoke from a 2-stroke is never bad unless you foul plugs because you are too rich. Remember: Be careful of black smoke or no smoke which is too lean.
