Older cr125, burned a piston probably due to air leak but yet to be decided. Can be felt slightly with fingernail. Would ya run it?

Not a chance. That's gunna catch a ring at some point in the very near future.

Specially not an a 125 that will be pinned all the time. detonation on top of piston?...plate it.....

No detonation

Looks pretty hectic, is that some pickup on the cylinder wall? You can clean it off with phosphoric acid which is a bit of painstakingly slow process but I have done the same on my 125 years back but that was just a small amount on a relatively new cylinder.

Prob wants a re-plate to be safe.

Yes it appears to be aluminum transfer, it's coming off slowly with soft scotch brite. I'm confident I can save it

do it rite.... re-plate
