With the 255 cams you can get by with the stock gearing but going to the 68t rear pulley should be on your list of to do items. It makes a nice difference and you do not need to change belts. You may be able to find a 68t rear pulley non-ids for your bike thru a wheel guy like Hog Pro, a forum sponsor.
Rear pulley swap along with getting bit better tune should help quite a lot wihout having to go the expense installing a new 2 into 1 ex system that may be louder then you'd like too.
I changed gearing only tooth on drive pulley on the last bike i had (1700cc v-twin cruiser) and it really made a noticeable diff in its upmh so with better tune & swapping out rear pulley that may satisfy you.
And if the situation calls for hauling butt like already suggested just down shift 1 gear (2 if required!) to better place motor in its pwr & trq curve to stay up with the larger 103 .
Thats where CI 's come's into play because your smaller 96" motor has to work a bit harder (down shift and rev a bit more) to enable it to keep up with the the larger 103that not downshifting in same passing situation.
And even with the new rear pulley you may have to still downshift to keep up with the 103 when passing ,but i am pretty sure you could stay with the 103 with new pulley,better tune & downshifting too hopefully without investing a new ex system that may be louder then you like or not sound like current system you already like a lot.
Good luck & let us know what you decide to do & how it works out for you.

I just saw you have an 08, LOL. You have IDS, All you need is the pulley and the bearing. Pulley is PN# 40508-08 and bearing is PN# 9285. You can replace the rubber iso pads while your in there if you want. You'll have to press out the bearing that comes in the pulley and press in the 25mm double row #9285.

Stock belt still fits, you can go to a smaller trans pulley at another time, if desired, like 30 or 31 and the stock belt will still fit. Gotta say you will love the performance of the D&D Fat Cat. Call AMS in Fort Worth for best price, I think you will be speaking to Eric. Whether or not you like the sound is personal, I love my Boarzilla a bunch, way quieter than the 2-1 it replaced.

If you ride 2 up often you'll really notice the benefits of the 68T rear pulley

As stated in an early post... head wind is my greatest enemy.. Bike really runs well. It just doesn't pull in a head wind like I think it should.

those 103 ho bikes haul *** stock !! I ride my Dads whenever I can !!
As others stated gearing is the issue, both primary ratios and final as well IIRC.
Just downshift, my dead pal had a 08 Ultra converted to a trike and he bitched about what a dog it was until it was suggested he just downshift on grades and passing, then he was happy.
