(From what I can see the 25 chain look pretty taught...)

It's not terribly hard to do if you have CAD. You can find the size of a link pretty easily, giving you a unit that we'll call one link. You find the exact wrap around the sprockets, which gives you a certain distance (x links, we'll call it). Then you find the exact distance between the wraps on both sides and get another distance (y links). Add x and y and you get the number of links needed. If there is a fraction less than 0.5, add a half-link (special link); if there is a fraction between 0.5 and 1.0, add one link. Make your chain that number of links long, put it on, and you shouldn't have to worry about tensioning for a while.
