Its always a good time to buy more tools.  But, seriously, you don't need
any special tools to bleed the clutch circuit on a 5000, just a special
technique.  It even worked fine when I replaced the clutch master (i.e.,
when the top half of the circuit was  completely drained). Here's what  you do:

1. Keep the reservoir topped up. 
2. Attach a clear hose (cheap stuff) to the bleed port on the slave cylinder
and put the other end in a jar that is higher than the reservoir.  You can
rest it on the cowl.  You need about an inch of fluid in the jar.
3. Open the bleed port and pump the pedal very slowly (~10 sec per stroke
and return).  After a little while, the hose should fill with fluid.
Continue until no more bubbles float up the hose.

Total time should be 5-20 minutes.

If you get desperate or want to get crazy, try to fill the clear hose before
bleeding.  You might even want to fill the fat hose from the reservoir to
the master cylinder (using a clean funnel?).
