Refilling a fork with oil by quantity only is notoriously innacurate, especially with cartridge type forks. There is only a modicum of accuracy if the fork internals are completely dry, INCLUDING the cartridge internals. Even though the cartridge may be repeatedly pumped to evacuate oil there will still be an appreciable amount internally, clinging to components. As there would be if the fork oil was changed only ( no seal replacement ) as there is still an appreciable amount of oil entrapped between the inner and outer tubes. Much as when you drain engine oil, theres still an amount left inside the engine.
Moreover OIL LEVEL is used as a tuning aid because it sets SECONDARY TRAPPED AIR SPRING COMPRESSION RATIO. Get the oil level too high and it will be too progressive in action, too low and it will bottom out too readily under hard braking.
Many of us want everything to be simple and cheap but its no longer a simple world. And frankly this is a job requiring understanding and special tools to get it right. Modern cartridge type forks do need precision in setting.

I do get what your saying Robert and agree. few points to consider.

1. not my bike
2. owner doesnt want to pay a shop to do it
3. In my experience (TM). Its a really long road finding a half capable mechnaic in the manawatu anyhow. Esp with Kawasaki so doing it yourself is the only way to make sure the job is done properly
4. When i got there and noted the lack of tools. Im like fuck this. Im not doing it with a beer, mullet and monkey bar. I like tools to to a job.
5. if his experience is anything like mine he will probably put it into the local kawasaki dealer and pay close on $300 to do it and then a week later give it to the local suzuki dealership to do the job properly and pay another $300 to do it properly
