I would think with only minus one tooth you could simply adjust the chain to its proper tension as you do for regular maintenance.

 

If you want better take off you need to get a bigger rear sprocket. 38 t stock you can go up to a 40t sprocket without changing the length of the chain. If you go bigger you can add links instead of getting a new chain. I do this all the time depending on what kind of riding I am going to do. If you want better take off you will lose some top end.
