Biggest problem is se260 cams. I found that at 95mph in 5th gear this thing really breathes great. Crack the throttle and it pulls like a horse. I just don't ride much at this speed or rpm. I'm thinking this tw400-6 cam will give me the power and torque at lower rpm where I will use it. I hope. I also feel that the throttle body is probably too big to give good response but I can live with this for now. I bought the bike with a stage iv kit already in it not knowing this is pretty much a rev and dump kinda thing. Now I just to want it to have some manners at low rpms.

JMO: This seems to be a problem with many who want to build a BIG motor...... (not you) Then find out it is Too Big, set up for the High RPM and not as responsive as wanted at low RPM..
Now for Your Buying the bike with stage 1V, I would think you are right on track to DE-cam it and what ever it takes to Make it smaller sized to get the Low End power you want.. You will have a Beast!
I agree on downsize of the fuel venture is needed, the cams are the first and main things to get re-done.... just that would make you a monster at lower RPM..
Old Thinking :
The bigger the better so they Put in the Big Cams and High compression pistons without regard to the Lower RPM torque values... and it ends up to Only produce power Later and at a very High RPM...
I have been there and done that....
The best power at low RPM, I have had, was In NOT going with Big cams in a motor, using Low com'n cams with a little more lift-duration than the stock ones. going with bigger bore and a little higher compression with a good ignition curve.....TFI
Hang on off the line!
