hey looking at getting just a single 40 webber off a mate whats the going rate on a pair and what i should pay for a single.

Here are some pretty broad guidelines. For Mikuni's divide the cost by half (but keep the performance expectation).

Freshly rebuilt pair $700-900. Depending on the finer detail (linkage connections, gaskets included, trumpets, additional jets etc etc).

Running pair been used and running well, could do with a clean and re-fresh $550-750?

Needing rebuild $350-550 for a pair depending on how complete.

Parts pair maybe $150 - 250.

It's always cheaper to buy a pair so add a little extra on for a single. Or buy the pair and sell a single.

thanks chriss. its in the ballpark i was thinking

you can get them new for @299us(dcoe 151 maybe) but they are made in spain i think now, dont know on the quality.
$600 plus a $300 on linkage kit and tubes etc.

edit..i was wrong 350us new
