Dragging the bike wont be a good idea.. Just shift the gears smoothly, 8-8.5k RPM is the best to shift to next gear.. Try engaging 5th gear as much as possible.
Shift the 4th gear at 10K rpm.. and after engaging into 5th gear drag it as much as possible.. give it a long run. Give the rest to back ..
And after first tuning.. Take your bike to long run.. and dragging the bike isnt the good idea.. as it stresses the engine.. may be you can do it once a week to do masti.. But it effects the engine negatively.
