25.6 is the diameter Chris, not circumference.
Have you counted the front one again? In a pic from your build thread you posted a pic of the sprockets you will be using and the front one was a 14 tooth.
I will have to pass on the beer as I don't drink. Just make that bike the fastest xs400 out there A 14 front sprocket would be like loosing 6 teeth off the rear. Your going to have a lot less acceleration.
Just use another clip style master link. That way you can just remove that master to use the 14t front sprocket when you switch them out.
If this chain doesn't fit with the new sprocket, what about a non o-ring chain? Would that still pass tech? If it's simply going to be used just for the mile then I don't see any issues, plus they're cheap and it's no where near as wide as an o-ring/x-ring chain.
