              Did you put in 640cm3 of 10w in then fill in the air gap to 125mm with a compressed fork leg (without spring). Filled mine with 640cm3 but bigger air gap than 125mm. Do I just top up to 125mm? Ta

         Yes. 640cc is just a general guide to get you roughly the right air gap. Whenever I have replaced the oil in forks on whatever bike, I've always had to add or subtract a little oil to gain the correct air gap. Just make sure the spring is still out and the fork fully compressed.
