Melted a Hole in My Piston
This thread started as me trying to find out how much compression a ninja 250 should have, the book calls for 139psi - 218psi, and they need about 125 psi to run.
I discovered that my left piston melted do to a lack of coolant (no idea where the coolant went, but in the place of the coolant was a tablespoon of water). My valvetrain looks good, the right side looks good, and the jug can easily be honed. I am undecided if I want to take this as an opportunity to sink another $400 into the bike for a 13.5:1 93 octane build, or if I want to just buy a piston, rings, gasket kit, hone the cylinder, and get her running for some better action later.
