Just a heads up with the tps if hard starting and the ECM draining the battery.
Had the same ATV with those problems. You can actually put the pod in service mode by jumping two pins- then adjust the tps according to the graph on the pod. For some reason my tps kept needing readjustment.

 

I have an '06 Arctic Cat 500. It's been loaned out many, many times to nephews, siblings, parents, cousins, etc, etc... I've used it for snow plowing, mowing, tilling, hauling, etc, etc, etc.... Still running strong after thousands of miles. I think there were 7 or 8 thousand miles on it when I replaced the original belt. I have also replaced one u-joint in the front axle that was damaged due to negligent riding.
