Dumb Motor Question

On my SXR one of the pistons is missing a chunk. it looks like the ring caught the exhaust port by the scoring in the cylinder and the looks of the ring. so my question is due i have to tear the case apart to check the crank, or is it safe to rebuild the top end? by the way it is a ported cylinder with stock pistons.

once I had that happen and I didn't open up the case. I missed a chunk in the case and had to do it all over again, I opened up the case the second time.
 
i guess that means i have to split the cases. do i split the cases and just clean the crank and stuff, or am i looking for something to be wrong with the crank?

Also get some new OEM crankshaft seals for it too, Don't use aftermarket replacement seals!
I second that
i have seen try and save some money and then end up paying more

Some times the more expensive option is the cheapest

Getting a GOOD shop to do your work also gives you a warranty as well
