f..igured it out...
the copper colored locking clip pushes into the tumbler from the inside and the lock slides out towards key entry.
the tumblers are super easy to shuffle into the new keys configuration. put it all back the same way it came out and your done.
the gas cap was a bit more in that the locking tabs are tension loaded so when you undo the first set of screws under the cap it spring open. careful not to loose the springs especially in the tumbler.
yeah yeah i know where are this pics.. maybe next time.
good news is- to re-key the gas cap and helmet lock is a simple 30 minute process
