Vinny,Unfortunately I only ever fitted Racetech and Debrix fork emulators, never had my hands on the YSS ones so am not sure if they're exactly the same :\ Those other Emus called for 2.5 turns of preload, along with 15w oil. I never found them overly harsh even with the heavier fork oil.
Re: airgap - my '98 service manual says standard fork oil height is 121mm from the top of the fork (with springs out and compressed). I am not sure if this changed for the revised forks from 2000 onwards. If you have a 1998/99 bike, I would try reducing standard height by about 10mm (so a 130mm gap) and take it from there. Put a cable tie round the stanchion to see how much travel you're using up.
For the full lowdown on YSS valves, you could try sending a PM to 'Tommyardin' as he fitted YSS emus to his forks and got a great result.
