There is a really good current thread with pics of all the components under the RHS engine cover and which ones to adjust. Just be sure not to remove the cover if anything is pressing against the shift shaft when you have the bike laid over.
Also try to avoid pulling on the actuator arm while its connected to the governor. It can disloge the ball bearings and cause issues. The other trick others like to use is to apply a little heat to the nylon locknut on the actuator plate before removing. A couple people have snapped the shaft off the plate being too aggressive.
Just checked and all this info is in the sticky -
