You should be able to use #40 drive axle sprockets and chain with the stock sprockets on your motors.

I am having great difficulty finding 8mm sprockets with 25teeth for my tank's drive axles to achieve a 1:1 ratio. I am also having a very hard time finding #25 or #35 sprokets with an 11mm bore and keyway to replace the odd 8mm on the mototrs. I am stuck with motors with a 11mm keyed shaft with no options. Any suggestions short of complicated modifications/welding of sprockets? I really dont care what size (8mm, #25, #35) sprocket and chain I end up using, I just need a simple solution.
