My bike is a 2008 with 9000 miles and I'm the 3rd owner. Do you think it's just rust from years of previous owners not changing it often enough?
Here is what I drained out and it ain't Old Orchard cranberry juice. It's 2am and I'm sleepy so please tell me it's okay to leave the all the coolant out of the bike until tomorrow when I can pick up some distilled wawa and some coolant. By the way, while it was draining out, the stream color was a dark orange but still kinda translucent.

Distilled water? You should just use 50/50 which is already mixed with the proper ratio of water and antifreeze.
Nasty! Does it smell at all like anti-freeze?
For flushing, just use city water (or xx ) as your simply flushing and dumping it.
As nasty as it is, I'd do a couple of flushes...
I've been using Prestone 50/50 for TEN years and there is NO mixing (as noted above), just pour it in and top off...
Can't screw up the mix... You can get about 3 full coolant changes out of one gallon..
No distilled water needed...
*BTW, I'm in SW Florida (hot & humid) and my engine temps seem to run cooler than other FZ's (roughly 180F) around town...
