105-164 psi. it is posted on a thread on like the 5th or 6th page. I have the manual at the shop. You need a manual, believe me. This site will fill in the gaps, but alot of things are year and model specific. Plan on the top-end rebuild. No reason to ride without confidence. You don't want to push that beast back to the truck.
You should be jumping with all you got to start it. If you can start it with a tennis shoe, then you need to go thru it. The good news is, you have an Electro-fuse coating on the cylinder, and if there's no damage, you are looking at less than 200 smacks.
