Seth, how's it going there?
I did this on my Viggen last year; all worked out in the end. First thing to understand, is that inside the brake reservoir, there is a wall that blocks off the fluid going to the clutch. IF you want to bleed it using a pressure bleeder, you'll have to make sure the reservoir is quite full so as to always have fluid on the clutch side. But, this is more complicated than necessary...
If you read here, you'll find that the secret is to "reverse bleed." I did this, and it worked however I thought of an easier method. Let me tell you what I did first. I got a syringe (40 ml?) and to the end of it I attached a clear plastic tubing which I forget its diameter (it was the same diameter as the tubing used to place over the caliper valves...). I then filled the syringe with super blue brake fluid, making sure the syringe and the tube had NO air whatsoever. I then placed a 9mm wrench over the bleeder valve, then the tube over the clutch bleeder valve came next. I loosened it ever so slightly until I could inject fluid through it (You'll have to go slowly...and you really only need to loosen it like 1/8 of a turn). I continued injecting until I could see blue fluid getting to the reservoir. I continued injecting and started to then tighten the valve. To make it easier, I made a mark on the valve using a marker to know where it was at, before loosening.
As well, and this was my idea so I am not sure if it us actually necessary, I attached a cable to the clutch and the cable tied to the headrest of my seat to pull the clutch pedal UP so it would no drop down. It worked GREAT, so I think it's a good thing to do.
The easier method, which I have yet to try, is to just fill the reservoir FULL of brake fluid, attaching the syringe and tube to the bleeder valve and sucking the old fluid until you see fresh fluid in the syringe, obviously all the while maintaining a relatively high level of fluid in the reservoir to ensure it always gets to the walled off clutch side. You may need a helper for this. As I said, I haven't done this yet but will very soon. I do not see why this wouldn't work.
Hope this helps and hope the Viggen's doing well.
