Clean well oiled filters are the way to keeping that engine happy. If the machine is already well tuned and jetted switching from stock to no toil to uni has never really changed much power wise for me. These things run best if they are a little lean, but that doesn't give you the longevity most people want. Running a little rich won't give you more power but does give piece of mind. If you are riding hard you are less likely to seize or cause damage. If you have doubts, go up one size on the pilot and main, see how you like it that way. Now if you are running stock and go to aftermarket exhaust you should have to rejet. Or adding airflow via altering the air box in some way.
