followed instructions that came in the manual.
Previous leftys lost travel as the bearings migrated – a ‘reset’ involved yanking the lower down.
This one (post 2012 prob) loses travel at the bottom-out end, so geometry doesn’t slowly change.
The ‘reset’ is the opposite too – take air out, bottom it out firmly a few times until the O-ring in 35mm from the bottom – air back in, check sag, done.
Not sure 125mm is acceptable though?!
