Issues viewing live data on Serial Monitor on Arduino Micro

I have been reading through all the documentation and forum posts I could get my hands on, but I cannot seem to figure out how to view live data on the serial monitor. I have been using a Arduino Uno for this (works beautifully), and I’d like to use a smaller (lighter) micro controller to get flight data (humidity, temperature, acceleration, etc.) from a rocket. At the moment, I am using the Micro and a Parallax L3G4200D. Assuming the wiring scheme is the same for I2C as for the Uno, I used the same code and got nothing:

#include <Wire.h>

#define CTRL_REG1 0x20
#define CTRL_REG2 0x21
#define CTRL_REG3 0x22
#define CTRL_REG4 0x23

int Addr = 105;                 // I2C address of gyro
int x, y, z;

void setup(){
  writeI2C(CTRL_REG1, 0x1F);    // Turn on all axes, disable power down
  writeI2C(CTRL_REG3, 0x08);    // Enable control ready signal
  writeI2C(CTRL_REG4, 0x80);    // Set scale (500 deg/sec)
  delay(100);                   // Wait to synchronize 

void loop(){
  getGyroValues();              // Get new values
  // In following Dividing by 114 reduces noise
  Serial.print("Raw X:");  Serial.print(x / 114);  
  Serial.print(" Raw Y:"); Serial.print(y / 114);
  Serial.print(" Raw Z:"); Serial.println(z / 114);
  delay(500);                   // Short delay between reads

void getGyroValues () {
  byte MSB, LSB;

  MSB = readI2C(0x29);
  LSB = readI2C(0x28);
  x = ((MSB << 8) | LSB);

  MSB = readI2C(0x2B);
  LSB = readI2C(0x2A);
  y = ((MSB << 8) | LSB);

  MSB = readI2C(0x2D);
  LSB = readI2C(0x2C);
  z = ((MSB << 8) | LSB);

int readI2C (byte regAddr) {
    Wire.write(regAddr);                // Register address to read
    Wire.endTransmission();             // Terminate request
    Wire.requestFrom(Addr, 1);          // Read a byte
    while(!Wire.available()) { };       // Wait for receipt
    return(;                // Get result

void writeI2C (byte regAddr, byte val) {

(code from Parallax)
I could use some help w/ this-I have used the “while(!Serial);” in other programs with some success, but not this. I think it might be placement, but I do not know!!
