Make sure you read it completely...this only works if you have a race pipe and are looking for 1-2 hp ?!?! Doesn't seem to make much sense for a street ridden motorcycle. My guess is that you will give up some low end power for a minor increase in peak power...not usually worth it. Personally, I would like to see real hard dyno data first (when I get a dyno, I'll be looking to do these kinds of experiments).
Rarely is the question stupid, but sometimes the answer is
you need to run everything you read online through your own personal BS meter to determine if it makes sense to you.
