I recently found a decent way of changing the pilot jet on the YFZ FCR carb that works very well without loosening and turning the carb. This jet is pretty far up in the carb float bowl and is acccessible thru the main bowl 17 mm hole. After removing the current pilot with a small flat blade screwdriver, it can be very difficult to start the new pilot jet in the carb, but by using a regular size tooth pick that is fitted in the hole of the pilot, the jet can be guided and started properly and then retighened with the small screwdriver. Hope this may help others when doing these changes.
