Drain the carb
Remove the 17mm cap
Insert a small screw driver up in the housinging and remove the pilot, reverse to reinstall

You may want to use a small mirror to see what you are doing. Be gentle.

Not the easy way.

Pulling the cap and swapping the jet on the bike is a one minute job. I think if you do a search in the jetting forum, a few guys have some clever ideas on how to hold the jetup there and get the threads started.
Also, always look at the bottom of the thread, there are suggested solutions there everytime. Some times, right on the money too.
