A delta force II (DFII) reedcage is made by moto tassinari.
If your jetting is good to start, it will be real close with the DFII.
I didn't rejet specifically for the radvalve/DFII swap I did. I DO rejet on a regular basis for temp changes, elevation ranges in particular riding areas and RH changes.
As long as you know how to jet a bike, what does it matter? If you know the advantages of proper jetting then you won't be satisfied until it's right given whatever mechancial setup you're running.
If I had to guess, I'd say you might want to be a bit more lean with the DFII than you are now. That's not because of the DFII particularly, but because most bikes are too rich anyway.
Still...a guess from anyone will not be a proper substitute for you sorting out your bike.
Get one. You'll like it.
