The powered vacuum systems work best and easiest on these bikes. Not cheap but not ridiculously expensive either. And it will save the nastiest words you know for a different project later on.... like adjusting the valves.

I'm sure I've mentioned this before, but I use a home made vacuum system that uses compressed air. I use a glass Mason jar with bulkhead fittings and an SMC vacuum ejector (for 1/4" tubing iirc). For my suction line(s)...I have a single line for things like clutch bleeding, or I simply plug-in a tee so I can bleed both front calipers together or bleed both bleeder screws on a single rear caliper (many under-slung rear calipers have two bleeder screws).
I can bleed and refill a complete front braking system or clutch, etc in only a few minutes. One man job, no drama, no mess. However, even home made, it did cost me about $100 worth of parts/fittings/tubing, and you DO need compressed air to run it, but it does work very well.
I'll usually cut a piece of cardboard to fit snugly over a brake or clutch master cyl (if they're the cast aluminum ones, and not the round plastic bottles like on most sport-bikes). The cardboard is a splash guard. I can turn the vacuum on very slowly, and then just pour new brake fluid in the reservoir.
Now I understand that most people don't want to spend $100 bucks on stuff/parts for a powered vacuum system, but if you hate doing it as much as I did, it might be worth it...lol.
What I did was basically build a homegrown version of this:
