Uni s and K&N s are pretty close to the same, a good job of drilling the airbox nearly equates with pods, there are so many variations of factory TOR s, and how much 1 baffle removed un restricts, the call on jet size is a hard one other than you will need to be going up. 134 s or 136 s may be close enough to dial it in from there. Another good upgrade are the brass idle/air adjusters that Fast Eddy sells, but most jet kits come with the special tool to turn the OEM ones. I run an 06 865 cc with a drilled a box, stock Staintunes (flow slightly better the factory TOR s), drilled out all the recommended places as per the instruction in the kit, 45&138 jets, kawasaki springs, Triumph T-Bird Sport needles and have experienced almost perfect results with a little fiddling. Don't expect your carbs to be perfect after the first mods, it can be a journey, but worth the arrival to final destination.
