Get a battery tender to put on the battery when you aren't using it to keep it fully charged. Check battery connections and grounds. Check the starter relay plus the starter and solenoid. Call an auto electrician. The videos may help diagnosis.

front of eng on left side

might have blown the powerpak or module when it shorted,did you blow fuses?

fuel filter is in the petcock where you turn the gas on and off

It could be a bad stator

Are you getting power to the coil its self

When you check on top of your carburetor ,while the engine is running, you will see fuel being sprayed from one of the jets.That fuel goes to the inlets,so if there is no fuel being sprayed that means there is a blockage on the jets where there is a float.Remove the upper part of your carburetor by taking off the screws.Becafull

The high speed jet isn't rich enough or the carb passages needs to be cleaned. You can move the clip down one spot on the needle so it gets more gas, this will also give you more power at the top end.

Sounds to me like you have a bad ground wire somewhere

hey Tammy... does the neutral light come on??? if not... find neutral..see what happens.. next.. have your batteries CCA checked.. (Cold Cranking Amps)...the amperage is what makes the starter work..NOT voltage...you can take it to Oreilly's, autozone, batteries and bulbs, or your local battery store...

look for loose wires and check the resistance of the plug cap

Hey.. sounds like you are on the right track.. DO NOT CRANK THIS ATV AGAIN!! GET IN TOUCH WITH A PROFESSIONAL MECHANIC. If you are going to do it... remove the engine..its going to have to be totally disassembled to make sure ALL the metal and rubber pieces are COMPLETELY removed. This will also provide you with the evidence for a parts list for replacements parts and pieces as you take it apart..slowly.. Clean parts make for a clean engine.. watch for small oil passages and any little nooks and crannies in the cases that will pack with ground up metal..COMPRESSED AIR and long wooden swabs work wonders. ps.. replace the cam chain no matter what it looks like!!!!!

check youtube for generic valve adjusting procedures, the kodiak is like most of them.

you might have to take it apart again and see whats up. maybe the new seal has come out of the slot and jammed it??

your carb needs cleaned/adjusted. your float could be set wrong. could be an air leak somewhere.
