Chaps, having spent some time working with suspesion, thicker fork oil will increase the damping effect (shouldn't blow the seals) which will reduce the amount of travel on the forks for any given impact, if you put spacers in to preload the spring you will effectivly stiffen the spring rate up a bit but you will not affect the damping, this should reduce the botteming out but retain maximum suspesion movement over the ruts.

Von, I think a strip down would be worth while mate, with new seals and fresh oil (think I still have some fork oil in the garage). I think we may need to check the seal around the allen bolt that is at the bottem of the fork leg as well a washer and some instant gasket should seal it nicely. I dont think we should go for much thicker fork oil, a light or medium wieght oil for off road use should be what we are aiming for.

What do ya think matey.
