What are you using for a freewheel? And what's the cog count for both the freewheel and crankset?
Make sure you torque the rear axle bolts and recheck them periodically.
Post some pictures of your setup! I got the freewheel from Harris Cylcery - a MegaRange Shimano 11-27T seven speed. It's got a new design that makes the 11T possible - it's very smooth and quiet.
