Before I start I must say we both have progressive Hagon fork springs and although these seemed promising when initialy fitted ( before this mod) that disappointing 40mm sag was still there and as we know most of the front fork movement is wasted before you even sit on the bike.
In addition we both have modified triangles that jack up the rear...again this improves the rear end suspension and ground clearance but tips weight forwards and the forks really show up!
So to the mod. The first part gets the spring compressed and provides a sensible bench mark 15mm sag.
Slarty,
I'm just about ready & good to go undertaking your fork mod. Now i have just acquired a headstock & rear stands from a mate, i have taken some preliminary measurements of the static & laden sags so i have a base point.
static sag is 9mm & laden sag (with rider) is 44mm. see pic below

pic is taken at static sag with the zip tie showing the sag with rider.
now these seem a whole lot more reasonable than the static 40mm you were getting before adding a rider, but until i get them open i don't know how they have been set up (air gap, preload, oil weight, plastic tube length, etc).
I have always complained that my forks were way to hard for road riding, giving a very jolting ride on bumpy roads. But on the track they have always been good. I think that i have the opposite problem from you in that my forks only seem to use the first part of their travel where as yours due to the sag used the last part of travel & bottomed out.
I'm going to break them down & take a look at how they are set up & i will start a new thread with pics & descriptions of my findings.
Cheers
