I'm sure you can run the 12t without issue, it just takes more effort to dial in the tension. The 14t has not been a problem for my bike so far. All 3 work, provided the chain tension is correct for each set up.
This and the fuel pump get kicked to death on this tread, primarily because the only real problems this bike has is with the fuel pump and the swing arm wear. If these problems didn't exist, the WR250r would be the absolute perfect Dual Sport... this would be a sign of the end times as there is no such thing as true perfection
