Gutshot + 2 Overs. Do I continue?

[neurotiq]

SB is 43/5/1.32.

I'm dealt K[img]/images/graemlins/diamond.gif[/img]J[img]/images/graemlins/diamond.gif[/img] in MP2. I open-raise. Both blinds stick around.

Flop is: 9[img]/images/graemlins/diamond.gif[/img]8[img]/images/graemlins/club.gif[/img]7[img]/images/graemlins/spade.gif[/img]

Checked to me. I c-bet. SB check-raises. BB folds. I call, figuring that with a backdoor flush draw, gutshot, and two overcards, I have more than enough outs to continue. I'm not sure if I should count a full 11.5 outs, but even if I shouldn't, I still have a few.

Turn: 9[img]/images/graemlins/diamond.gif[/img]8[img]/images/graemlins/club.gif[/img]7[img]/images/graemlins/spade.gif[/img]4[img]/images/graemlins/club.gif[/img]

SB leads. Am I continuing?
