You can take the engine apart, but you will need to factor in the cost to replace EVERY seal and gasket on the motor, save for anything that may use an O-ring.

Are any of the bolts torque-to-yield? If so, they're garbage and will need to be replaced as well.

If anything internal is broken and/or scarred, you will need special machines to fix them- which you most likely don't. Machine work isn't always cheap, and you also have to wait for it to get completed.

If you have some mechanical know-how, I'd yank it out and pull it apart and see whats what. You either spun a bearing, and as bad as your description is it likely took the crank with it, too.

Or broke a ring and seized the piston in the cylinder, which would require a new block or a re-sleeve(if they are available on the 500), and a new piston.

Given the options, I'd get a new motor installed. Then pull apart the old one and see whats going on- at least its fun to do!

Just wondering, was your oil low? If so make sure what ever you do you follow the tclocs process so this doesn't happen again.

hey bro, here you go.... I'm guessing you can get the motor for $400. I Might even be able to help you install it for a 6 pack or so. Of course not to drink during the swap. It should take about 3 hours im guessing. Hope this helps.

This will be a good learning experience for you to get your feet wet.

A few days later, I opened the alternator side and tried to turn the flywheel, it was stuck.
I probably need a new motor, so where can I find a (gently) used ninja ex500 motor in town? Or can I fix this? If so, how?
i have a 500 and althought it wasn't this bad off, it did have a few symptoms that you have described above. i couldn't jump start it either. i bought a brand new battery, already charged for $70. put her in and she started right up , runs like a champ.

u may have tried it all ready, but if not i 'd highly recommend it for one last chance to save u a boat load of $$$
