ah then the link is useless, sorry.
perhaps the guy who revalved it might have a suggestion.
I would check the axle alignment the oil level and the main spring prelaod if you haven't allready.
those stacks look very soft, stiffer might be nicer.
sometimes the mechanical side of the whole thing can be overlooked prelaod, tight seals, alignment bushes etc.
and yet another angle: while increasing the travel isn't really that good on a bike with 310mm ground clearence we have about 370mm clearence so 320mm fork travel should be a minimum. with more travel my 0.44 springs work like 0,51s would at the end of teh stroke in your bike. I can also run a rediculously low oil volume and hardly ever bottom out.
good luck with it.
stock stacks below the stock MV spring is very stiff so you can't really go back to stock without one.

Top out spring is 32mm long wire is approx 2.55mm diam and spring OD is 19mm
Oil height measured on disassembly 120mm
FWIW I would try a single stage BV, a mid with 1.2mm or less float and drill a 1.2mm bleed hole in the MV. the stock HS rebound is allready too soft IMHO and will need further stiffening with a bleed hole in the mid.
