How long are you running the Keyangs before they overheat? You may be wasting a lot of power on friction in your drivetrain. Try this, disconnect your drive motors from the drivetrain. Lift your drive wheels off the ground and try spinning the wheels by hand. If you can't easily spin the wheels, then you've got a friction problem. Here are a few things to look out for:
1. Make sure your axles are aligned. Bent axles create a large amount of resistance.
2. If you are using bushings with shaft collars, make sure the shaft collars aren't rubbing against the bushings too tightly.
3. Your chain should have some slack in it. Don't try to over-tighten the chain by removing an extra link. Just use some PVC, a fender washer, and a bolt to make an idler.
More power to Ya!
