Fork dismantling tool - yeah or nay - Sorted

[Jez]

No - You don't "need" one full stop. You could use one if you wanted to fully disassemble the forks which you probably don't if it's just an oil change, most folks manage without though.

That's encouraging. I may still be missing something. How is it possible to measure the oil level without removing the spring? Or maybe the spring can be removed without disconnecting the damping adjuster?
