Thanks a lot for the info. I am thinking I will do the 30T pulley and belt next, and see how that improves the acceleration. I don't really want to do more than I have to, to get the bike's performance where I am fully satisfied.
What pulley did you use, and what belt? I am thinking the H-D Tri Glide pulley (less $ than Andrews), and the Gates 139T belt.
You're right - chasing HP can be a VERY expensive proposition! Maybe I'll bump the compression and get the heads done... but I don't think I want to go whole hog like you have. If I decide to spend truly big bucks, I'll likely just put in a 120R and be done with it.
BTW - I am LOVIN' this Corbin seat! Fits me like a glove! 
Glad the seat is working, I'm really liking my C&C that I got, so it worked for both of us.
I went with the Andrews pulley, mainly because I think the trike pulley was on backorder & I got my belt through drag specialties, I've got the Falcon, I believe the one everyone is having problems with. I've got somewhere over 3000 miles on my belt. We will see what happens when we open this new motor up. Mechanic says shouldn't have a problem, need to keep it tight, not let it get loose.
If I was to do it over, I would possibly just mod the swingarm & keep the stock belt, but I don't know. Love the mod tho...
If you do your heads, bump the compression & I would say throw some cams in there while tore apart & you will love it!
All the work I did is kind of a blur looking back, changed cams twice, throttle bodies, but it ran awesome!
I ran my brother-in-law who has the exact same bike, bone stock, except he has vance & hines head pipe with rhinehart mufflers, ran him after mild head work from baisley, woods 7 cams & the D&D exhaust and I just barely pulled him. Did the 30T and then could moderately walk away from him.
Sorry to go on & on - you'd probably be satisfied with cams & 30T and a good tune, after that it gets pretty expensive to gain very little, that's what I've learned...
But now....got the call today the exhaust came it & he was heat cycling the motor tonight, so there is life back in my bike once again...I can't wait to get it back & get somewhere warm & away from the salty roads to see what I've got now!
