The motor is not an all around motor. It has very nice upper end and some mid, but as far as the bottom end............ Everyone always says that cubs have no bottom end, I think this is referring to the torque aspect. No, there is no torque down low, but my experience with my shee is that it is really close to the response I had down low when it just had pipes and stock motor. But there is a hell of a lot of difference when the powerband hits.
But yes it is definately a drag motor...................
If you wanted the all around motor you do need to look at haveing your stockers ported, I think you would be much happier for the riding you are talking about.
You have already heard from Jeff at FAST, but you may want to still give him a call and get more info. But an FYI, he's very busy this time of year so be patient. The reason he's busy is because he's good at what he does..............
Just my .02
