Aaaawwww... Dude! Soooo much easier than stock! The needles, which about
are long as shish kabob squewers are easily accessed by two allen head
bolts without removing anything! (except the tank cover) The fuel jets
are at the bottom of the bowls which are outboard, and can be changed
without so much as removing a scoop or tank cover! All I've had to do
since getting them is raise the needle clip one slot, perfect ever since
I love these things, wish I'd got the 41 mm's
