Re: Dual CIMs and #25 Chain
Without pictures, this is something of a guess, but I do have a suggestion.

Replace the chain that runs from the transmission to the center wheel with 35 pitch. Keep the other two chains (from the center to the outer wheels) at 25 pitch.

As was posted earlier, the chain from the transmission to the center wheel is going to have 2-3 times the tension as the other two.

Just about everyone (including most of the "WCD" crowd) uses 25 pitch chain, but they do not have a single chain taking the entire load on one side of the robot. Replace that chain with 35 and you should be good to go with little or no other modifications.
