The job took me 4 1/2 hours,that included drilling the 6mm bolts out that hold the mudguard on.
I Set the fork air gap at 143mm from top with fork compressed(and spring removed) with about 520ml of10w synthetic fork oil.
Must say the bike feels alot firmer at the front now,it doesn't dive under braking as it did before, also feels better damped over the bumps,mind you the oil that I drained out didn't look good.
