Interesting... I wonder if it actually works.

I have seen first hand before and after. I can say yes..hell yes it does

Is that with no other changes? No muffler, air filter, jets or carb changes?

Nothing justthegrindi g of these crazy veins that are specific depth and a specific angle..took about 5 years of testing to findthe sweet spot.

That's very interesting. :) I wish your friend good luck.
