Im selling a partial kit for 40mm dells.
from the kit Im selling: venturis, discharge tubes, air correction tubes, and main jets.
Im selling everything you need to switch over to the horizontal discharge tubes.
here is some more info on it: read from cb's site
what is not being sold is the gasket/rebuild kit and the idle jet stacks.
these parts are not needed to make the switch.
this is very easy to swap and is proven to add power.
$55 shipped
