Thanks laz again. Very helpful, taught me quite a bit about I2C that I didnt understand in just a little snippet of code. Thanks to your help though I have successfully got it working extremely well. The biggest issue was not so much the bumpyness of the road, I was able to tune it out and use a band pass filter + some averaging to get that taken care of. It was the high frequency engine vibration that was killing it. The quadcopter guys have the same issues with there motors and sensors. I was able to completely fix this by mounting the system on the bike with some padding and velcro.
