Upgrade advise!
Well I will have a little extra change in my pocket come January, with that said, I'm thinking about going from a 2009 96 to a 107.
currently I have already had my heads worked on to 10.1. polished and ported.
Ventilator air cleaner.
T-Max
Adjustable pushrods.
Rineharts true duals, with 3-1/2 pipes.
SE 255 Cam.
So here is what I want,
SE 259 cams.
SE 107 flat top pistons.
The guys who did my heads will bore the cylinders to 107.
This is my question I don't know about.
Will I need to get different injectors for the 107?
Will polishing the 50MM TB be worth the cost?
And how bout those SE Lifters? will that make a difference?

I would talk to the guys who did your heads. They should know what pistons and cams will go with the heads. Stock injectors and intake can handle most 107 builds but it would depend on your combo. There is no real reason to replace roller lifters with a cam change. There are better choices than SE lifters out there.

A great running 107 with ported heads is going to be somewhere in the neighborhood of 110hp/120ft-lbs. Your combination now is making what....maybe 15-20 less on each side? You'll pick up more power with a better exhaust and tuner, but.....
15 ft-lbs is noticeable, but it's not going to be earth-shaking compared to what you already have. For less money you could upgrade to a pair of JRI shocks and something (Intiminators, Monotubes, whatever) for your front forks and have a night-and-day different bike.

Met with my engine guy today, he sated he wanted to go with Andrews 408 cams, and Wiseco 107 pistons.
He stated this will fit in with the work he has already completed with my heads.
05 Train, I'm using a Thunder-Max tuner, that is the Cadillac of tuners,
as far as exhaust, I an a traditional looking guy, I don't like the look of the 2 into 1 exhaust look, I know it's a better output, but I'm a little old skool, and have to give a little in performance!!!

Normally I agree with asking you head porter about upgrades, but the Andrews 48s, they don't make a 408, isn't a good choice for a 107, especially if you are already running 10.1 CR in a 96. Just going up in bore from 3.75 to 3.93 will raise your CR by about .8, giving you 10.8.1, way too much for 48s. I question whether you actually have 10.1 now as that is very high for SE255s, & would make for a hard starting engine, especially without comp releases. The first thing you need to know is what your heads CC at so you can figure out which path to take with cams. You can do a ccp test, a cranking compression test with a good comp tester to give you a reasonable idea of what you have now, but it would be best to remove the heads to see what size the chambers are before deciding which direction to go. It sounds complicated, but to get a good build you need the right mix of parts.

Steve at GMR did 107 in my bike with his genesis 577 cams along with S&S power tune duals (2-1-2) which replaced the v&h true duals I had on.
110hp, 120tq. It gets 100tq@2,300~5,700rpm, 110tq@2,700~5,200rpm.
I'm very happy with it!
