$1,500 for the pair.
When you factor in $USD -> $AUD and shipping costs + cost of cores and customs duties etc.. + 3 month wait. I've basically just recouped my spend. So likely won't do this again.
Easier ways to make profit that's for sure.
$1,500 sounds like a lot but I can tell you from experience rebuilding my Mikuni / Solex it's a bargain price and not having to wait 3 months is a huge bonus too!
You could also sell your original SUs for a few hundred also.
