I just heard about doing this today but they did not say you have to take the pump and the shock off the bike to do it and no one said anything about drilling a hole, so I guess my question is this. Can it be done W/O removing the pump and shock, where are the detailed instructions and how much will this improve the ride for the passenger? Is this basically making the piston compress and liquid istead of air and it that what makes it ride softer. I would think since liquids do not compress air would be better. Please explain how putting oil in this pump makes things better.

You can do it by just removing the pump, unbolt the right bag and rear fender and the bag will pull out enough to get to the pump.
The usual cause of passenger discomfort is the shock bottoming out, not that it is too stiff. All the passengers I know of have said the ride is much better after installing a stiffer (progressive) rear spring.
