Don't rack until they've flocculated and settled. The fact that you still have krausen means that they're still workin'---don't screw with em now. I brewed an immense barleywine 10 days ago---SG of 1.123, based on ProMash's calcs...BWAH HA HA! It's in a plastic bucket, so I'm not sure if there's still a bunch of krausen, but I'm betting there is, considering that I still get a few bubbles every minute. I'm leaving it in primary for another week or two, then pitching again--this time w/ champagne or strong ale yeast--and racking when it's done. Of course, this is a barleywine, but, still, with an OG of 1.083, just give it time. For instance, I also brewed a BIG porter last weekend. SG of 1.062, and it took every bit of 7.5 days to finally fall out.
Patience, grasshopper.
PS: what's your airlock activity looking like?
