Heres a few things I need you to do.

Turn that piece of skirt over & see if it has wear marks on it from touching the case.

Those hone marks in the cylinder bore, rub those & see how deep they are & are they realy straight not X shaped or is the pic fooling me.

Measure the piston & then the bore to see how much piston to cylinder clearance it has.

Never seen just the sleeve skirt break off by itself. Most times it happens from a busted piston skirt thrashing around & end up taking out the sleeve.

Has a piston ever busted any time before this.

The damage on the crank realy dont look that bad & you would think you could just smooth it out & run it, but, theres a lot you cant see, those tins have been distorted in that damaged area & probably have lost its seal somewhere around the edge & will start to breathe as the engine is running.
With the breathing come flex & then cracks & will come apart if you try to use is.

I can tell you first hand what an R engine ends up like when the tins come apart from a crank, you end up with all the parts under the clutch cover & the transmission to re-use in another engine build, that is if none of the case went into the transmission area & tore that up.

Hey, did you have this bike posted up for sale a few days ago.
