IMU Data in real-time to PC

Using Arduino Sensors
5

I'm only interested in the accelerometer and the gyro-data
I've tried now a baut-rate of 250000 (Arduino 101) but its only possible up to 250 Hz...

I used this code, but somehow it didn't work

#include <SPI.h>
#include <MPU9250.h>

#define SPI_CLOCK 8000000  // 8MHz clock works.

#define SS_PIN   10 
#define INT_PIN  3
#define LED      13

#define WAITFORINPUT(){            \
	while(!Serial.available()){};  \
	while(Serial.available()){     \
		Serial.read();             \
	};                             \
}                                  \

MPU9250 mpu(SPI_CLOCK, SS_PIN);

void setup() {
	Serial.begin(250000);

	pinMode(INT_PIN, INPUT);
	pinMode(LED, OUTPUT);
	digitalWrite(LED, HIGH);

	SPI.begin();

	Serial.println("Press any key to continue");
	WAITFORINPUT();

	mpu.init(true);

	uint8_t wai = mpu.whoami();
	if (wai == 0x71){
		Serial.println("Successful connection");
	}
	else{
		Serial.print("Failed connection: ");
		Serial.println(wai, HEX);
	}

	uint8_t wai_AK8963 = mpu.AK8963_whoami();
	if (wai_AK8963 == 0x48){
		Serial.println("Successful connection to mag");
	}
	else{
		Serial.print("Failed connection to mag: ");
		Serial.println(wai_AK8963, HEX);
	}

	mpu.calib_acc();
	//mpu.calib_mag();

	Serial.println("Send any char to begin main loop.");
	WAITFORINPUT();
}

void loop() {
	// various functions for reading
	// mpu.read_mag();
	// mpu.read_acc();
	// mpu.read_gyro();

	mpu.read_all();

	Serial.print(mpu.gyro_data[0]);   Serial.print('\t');
	Serial.print(mpu.gyro_data[1]);   Serial.print('\t');
	Serial.print(mpu.gyro_data[2]);   Serial.print('\t');
	Serial.print(mpu.accel_data[0]);  Serial.print('\t');
	Serial.print(mpu.accel_data[1]);  Serial.print('\t');
	Serial.println(mpu.accel_data[2]);  Serial.print('\t');
	//Serial.print(mpu.mag_data[0]);    Serial.print('\t');
	//Serial.print(mpu.mag_data[1]);    Serial.print('\t');
	//Serial.print(mpu.mag_data[2]);    Serial.print('\t');
	// Serial.println(mpu.temperature);

	delay(10);
}

The serial monitor shows values but only zeros, even if i shake the sensor...

Has anyone a code to run the sensor with spi? I couldn't find a code using google. All codes use I2C to run the sensor.
Thank you
