My problem in not with the take up of the clutch pedal. It is with the change in acceleration at 1/2 throttle 4000rpm when I press the pedal DOWN (clutch disengagement) when doing the 1-2 shift.
Like I said previously, if I shift from 1st to 2nd at 2500-3000rpm without hard acceleration, it is smooth as silk.

The only way I have tried that can reduce this problem is accelerate 1/2 throttle up to 3500rpm so I have hard acceleration, then ease off the throttle a tiny bit for the 3500-4000rpm range and then shift so that the change in acceleration when I press the clutch is not as drastic.
you can try to shift after 4000rpm, given that the engine develops its peak torque at 4500rpm. which mean, you can use full throttle till 4000rpm, then reduce the throttle a bit and upshift.

but like what the other forumers said, the pax will still get a sensation of decceleration.
