Hey buddy, i got the same problem as you its NOT the battery and the charge it drains itself because of not enough power to run it, it could possibly be leaking onto 2 red wires with a plastic cap in the middle, that's your fuse, if that's broken from the acid you need to replace the connectors and fuse. jump starting it is hard on the atv so careful how you do it. Also if you haven't already, clean your gas tank it has debris in there from the plastic shavings and gets clogged in your fuel filter so flush the tank (have an experienced person help you) and replace the filter (Wal-mart $10 doesn't have to be the same) Next be careful with the fuel on/res/off valve it will break off after extended use, that might also have crap in it. if u have a dad/relative/friend who is good with Suzuki engines have them take a look and clear it out, it should run perfectly after that. Good Luck
Oh and btw. Since its a Suzuki 4stroke 300cc engine you can buy aftermarket parts, just consult a dealer before you purchase said parts.
