Even though this thread is out-dated, I'd like to add my two cents.
When using a vacuum method, be sure that you're bleeder valve has "Thread Sealant" on it, otherwise you *will* draw in air via the thread, making it difficult to know if it's air in the line or air you're bringing in.
Make sure you know the difference between Thread Sealant and Thread Locker. Sound obvious, but some actually use the wrong one.
Also, I've seen many threads on many forums saying to use and not use Teflon tape. Brake fluid will eat the tape and turn into a gummy muck. Best to use proper "Thread Sealant". You won't need much and you'll get a great result.
PS: My 500 doesn't have the bleeder valve on the Delay Valve, so I have no way of bleeding that. Just have to make sure I dip the bike on a forward leaning angle for any caught air to go up.
Best method I've used so far for bleeding the brake is the "Reverse Bleed" Check it out on YouTube. It's a very quick way of changing the fluid and ensures you push all the air up the system, not down.
Cheers!
