Yorkie,
I ran into the same dillema as you while installing the jet kit. The instructions talk about drilling out a factory cover for the pilot jet...after a little research, it seems as though the instructions are referring to the air-fuel mixture screw that is near the float bowl. It has a little cap on it and the tab on the cap requires removal. I filled mine down until it would pass by the tab on the floatbowl. Removing the tab on the cap will allow you to reset the air fuel mixture screw.
Typically, it is turned to the seated position and then backed out two and a half turns.
Here is a breakdown of what I did just last weekend.
1. washed motorcycle, ran bike with fuel petcock in the off position until it stopped
2. removed left and right side panels, gas tank, seat, and charcoal cannister.
3. removed throttle linkage on right side of bike. (involves disconnecting rear brake resevoir.
4. went to left of bike, removed choke linkage (I broke the linkage mouting nut when re-installing it into the carb. Use caution, it does not require very much force to remove or install).
5. Loosened clamps that hold carb in place.
6. quick clockwise twist of carb to free it up for removal then removed the housing that connects the carb to the air box. I just pushed it back and right towards the frame rail that runs near it. It held it in place.
7. Gently pulled carb away from head while twisting side to side.
8. carb was set free, I took a picture of all the vacuum lines, then removed carb from bike (it took a little finesse to get it through the frame).
9. removed float bowl, replace main jet (stock was a 152, I put the 160 in).
10. replaced float bowl cover.
11. started working on the top side of the carb, removed slide cover (four phillips screws).
12. replaced stock slide spring, removed needle jet (just took a correctly sized phillips screw driver, pushed down and turned to release the little plastic piece that holds the needle valve in place. Replaced stock needle jet with the one supplied in jet kit.
13. Re-installed slide cover, and reversed the order of removal starting at step eight.
***I ran into trouble with the bike running properly when I used the 165 jet. The bike ran fine until it warmed up, then it stalled and would not restart. The second time I took all the stuff of and replaced the 165 jet with a 160 it only took about 10 minutes and the bike runs fine. Again, be gentle when reinstalling the choke linkage nut, mine was brittle and broke with very little effort. Fortunately, the shop in town had a replacement.
Good luck, it is not a difficult job at all. By the way, did you buy the stage one jet kit?
