a couple questions

[Sundevils21]

typical Party Poker 2/4 Hold'em (10 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Preflop: Hero is BB with 7/images/graemlins/spade.gif, A/images/graemlins/spade.gif.
<font color="666666">1 fold</font>, UTG+1 calls, UTG+2 calls, <font color="666666">5 folds</font>, SB completes, Hero checks.

Flop: (4 SB) 9/images/graemlins/heart.gif, 9/images/graemlins/spade.gif, J/images/graemlins/diamond.gif <font color="blue">(4 players)</font>
SB checks, Hero checks, UTG+1 checks, UTG+2 checks.

Turn: (2 BB) K/images/graemlins/spade.gif <font color="blue">(4 players)</font>
SB checks, Hero checks, UTG+1 checks, UTG+2 checks.

River: (2 BB) J/images/graemlins/club.gif <font color="blue">(4 players)</font>
SB checks, <font color="CC3333">Hero bets</font>...

this is a clear value bet on the river, right?
should I have bet the turn?

I would bet the turn. I have a lot of outs, my hand may be best, people may put me on K/9/J and fold low pocket pairs, and no one seems to want this pot.

People may call this river to play the board. Probably the bet is worth a try.

Bet the turn. Just do it.
