So how does it work? The 0.90kg/mm fork springs are a big improvement. Sag is where it needs to be with minimal preload, and the fork no longer dives alarmingly when I grab the brakes. Damping is still an issue, though. Initially we tried 7.5-weight oil, but it didn't make much of a difference compared to the stock 5-weight oil. Even with 10-weight fluid, low-speed damping is still too light in both directions, while high-speed compression damping is too severe. Further improvements will have to come by way of revalving the damping piston or, more likely, replacing it entirely. And, possibly, adding a cartridge to the other fork leg.
