I think the power gains are minimal but it's a "free" mod so go for it.
I used a pneumatic die grinder to do mine but many people use a Dremel tool.

pull the header off your quad. on the inside there will be a weld ring in each hole, grind that off with a die grinder and then polish it as smooth as you can get it.

anybody got any better pics of it, those ones on the thread are not to clear.
