Keep using the wider, XR650R C/S sprocket. Also, make sure you lubricate the countershaft with grease before you install another XR650R C/S sprocket.
I think your countershaft splines would have been stripped by now if you had not installed the wider, XR650R C/S sprocket.
Spud you have been a great help both during and before this trip started. I almost got around to making some chain rollers before he took off but ran out of time.
