Picked up this 2002 Yamaha Kodiak 400 4x4 for free. My buddy's neighbor was getting ready to haul it off to the dump. Asked him what's the deal with it and he said had been running fine and then one time he went to start it and it would turn over a bit and make a clicking sound coming from under the seat which I believe is the solenoid and couldn't get it to start. After that it stayed parked for about 2 years outside. Said he didn't have time to mess with it.
I got it home but didn't have a battery for it. Tried connecting my battery jump pack to it and see if anything would happen. With the key on no dash lights or headlights came on. I tried jumping the solenoid but just sparked a couple of times. Figured I'd try to turn the engine over by hand next.
The internals of the pull start are missing so I removed it to get to the crankshaft bolt and removed the spark plug. Put my ratchet on it and it wouldn't budge at all, not one inch. Feels completely locked up. I tried filling the cylinder with WD40 for a few hours to see if it would help but no luck. I added some marvel mystery oil into the cylinder and let it sit overnight and still no help.
I decided to remove the starter and make sure it's not locked and it spins freely. I removed the crankcase cover to see if maybe something looked broke back there but all looked good. At this moment I plan on letting the mystery oil sit for about a week and see if it frees up anything which I doubt.
Without have to tear into the engine do any of you guys have any tips or tricks on what I can do to try and get it unseized?
