Correct...... can’t drain ABS II forks without removing them and inverting?
The drain bolts got omitted on '96 onward ABS-II/CBS forks...
Taking them apart to flush all the crud out and inspecting the Teflon coated bushings wile at it, is more effective anyway.
(fun fact: the new spare fork bottoms for my '00 standard/non-ABS didn't had them drilled anymore either... thought about drilling & tapping for originality, but cancelled in favor of flushing...)
