swapped gsxr motors and bike wont rev
 

this has happened on two different gsxrs i have swapped motors on. motors ran fine for both before swapped but now on both an 07 and 09 the bike will idle fine and from idle if i got 100 percent throttle it will stall out but i can roll in to the throttle and it will slowly rev and then i can go WOT.


i thought i plugged everything in, i just find it real weird that its on BOTH of the bikes. please help guys! thanks!!
