This years Winter project will be fork maintenance. I've had the bike about 5 years now and feel as if the damping is not as good as it was when I first bought it so am thinking the oil has had it. I've never been unhappy with the forks performance until recently and when I had help setting them up a couple of years ago was able to discern a difference in each adjusters setting so I'm assuming that they have had some work done on the internals but won't know for sure until I open them up.
I'd appreciate any guidance / hints / tips from those that have undertaken a stripdown & rebuild of the forks - other than oil & seals will I need to purchase any other parts / tools / fluids, what oil is recommended, if I find the springs are OEM should I replace them and if so what with, is it worthwhile renewing springs anyway if they are at least 5 years old? If it helps I weigh 23st and have more weight over the front than stock via a jack-up kit, height adjustable shock and having the forks through the yokes by ~12mm, riding style is fast on minor A roads (lots of bends and not the best road surfaces - so forks are working hard).
