Answered: Help?...

ANSWERED: Turns out a motor was plugged in the wrong port. Runs great now though!

I just finished creating my masterpiece robot. It is 25x35(longer than it is wide),
has a 24:15 chain ratio, four motors to four seperate drive shafts, and has tank treads along either side.
Now here’s my problem…
One side goes about 1/4mph backward, and 1 mph forward.
The other side goes 2-3mph forward and backward.
All motors are facing the same direction so they’re all going the same way. I’ve checked and found that it doesn’t appear to be more friction on one side. It is identical on both sides. Except a few differences. The two rear motors have a slightly longer chain than the 2 front, and the rear have slightly more tension (this is because all the motors are facing the same way).
But the one side, with two different chain lengths and tensions is perfect, but the other side is, well… not perfect. I have six pictures here:
