Two holes if you consider the entry and exit hole to be one hole, otherwise it can also be expressed as adding four holes per rod.
My story on the Racetech installation... I'm an owner of a 2nd gen bike. Well, another rider and I were doing the install at the last tech day when it was discovered that nobody had the rod holding tool for the 2nd gen bike. A well-respected guru that was present at the time told us that we'd never get the dampener bolt tightened again without the tool and suggested that we go ahead and install the Emulators without the usual tear down and rod drilling, which, being 500 miles from home, I did. As did the other rider.
There is a noticeable increase in anti-dive properties and a slight improvement over square-edged bumps. I already had stiff progressive wound springs installed up front, that's where the stiffness comes in, not from the Emulators.
Since the tech day, the other rider decided to take a chance and disassemble the forks and do the install properly, using a broom handle in place of the holder tool and a helper. Changed the fork level from 135 to 150, as well. Reports a night and day difference. Says he hit speed bumps at 50 and the wheel just tracks, I guess that's good not really sure.
I will be following suit eventually.
