   question Is if I put 44mm bike bodies on do you think ill gain any more power
   or will I just loose my 142lbsft torque ?

   unless you've got a fancy inlet manifold to fit the bike bodies to I think it unlikely you will see any power gain. You need to question whether you are seeing strangulation of power due to not enough airflow. Bigger is not always better.

   no very unlikly to do anything but make lower end worse.
   look at your power graph -if it does not go flat fro last 1000rpm --then no restriction
   and even then it could be exhaust or something else
