Cugsy, that spring is so short that I would be concerned with spring bind.
It looks like a stocker that has been "seriously" cut down.
I'm not familiar with the RaceTech Emulators.
Possibly they use an ultra short spring, but I don't think so.
Assuming that is a stock spring that has been cut down, the front end should be really stiff?
Makes me think the bike was set up for a really heavy rider.
I think at this point; I would take the forks apart for an inspection. (to see if the forks have been extensively modified)
I would get my biker friends (ie: Boomer/Hans/anyone) to send me a stock set
I would modify a stock set by removing the 5 1/2", or buy aftermarket springs.
When you reassemble, don't worry about the volume of oil.
dump oil in each fork leg (specified volumn plus more)
exercise the fork to get the air bubbles out
compress the upper tube (spring removed)
**suck the excess oil until it reaches a desired level
set the oil level to a measured level (I recommend 6 1/2")
** If you don't have a tool to suck the oil out, you can build a cheap tool, by using a Turkey baster and a section of hose.
Ride safe, Ted
