If the voltage regulator is not the one I believe they they use it may not cut out at 4.5V dropping power to the MPU but there is a voltage drop across the regulator that could reach the low limits of the MPU or the Arduino input (i2c buss) and int pin (usually pin 2 on the uno).
The MPU6050 can handle as low as 2.375V with a max of 3.46V found on the datasheet. Now there is another issue to consider what is the lowest voltage your ATMega MPU considers as a HIGH value so the i2c bus can work. we are pulling the i2c buss high from the 3.3V side of the MUP6050 breakout board regulator.
To be safe
If you have the voltage regulator on the MPU6050 breakout you can use 5V, not that it can't work by powering the breakout VCC off of 3.3v it gives you a better chance that nothing will be out of limits. I'm concerned that there would be problems by the fact we are outside of design specs on the MPU6050 breakout board.

I've changed the offsets to myown ones, it is still not working. My connections are:
Mpu to arduino:
VCC-5v
GND-GND
SCL-3
SCA-2
AD0-GND
INT-7
servo motor to arduino:
yellow-13
red-5v
brown-ground
