Just a note to anyone building the kit.

If you are having trouble getting the sprocket to line up with the holes in part MH3 check that the washer (ME2) is centered on MJ5. The hole in the washer is larger than the diameter of MJ5, so if you don't pay attention as to how far off of center it is after tightening ME1, it will keep the sprocket from going all the way on part MH3. There is an opening on the inside of the sprocket for the washer and if off center a great deal, it will keep it from going on all the way.

This wasn't an issue when I built it, but after taking the final drive apart after running and cleaning, I couldn't get the sprocket to go back on. Originally, I thought that the end of the assembly was too far into the sprocket and rechecked the spacers and such. Then I looked at the washers and saw that they were way off of center.
