Would you replace this cylinder or reuse? (pic)

Recommended Posts

I am rebuilding a 110cc 4 stroke. Its kids toy, nothing serious. As the dead engine had lost compression and appeared to have a toasted exhaust valve I ordered a new head, and new piston and rings already. Would you reuse this cylinder? It has tiny vertical marks but no major gouges. Since its China parts its not going to last forever... We talking a cheap project pit bike here.

Engines are $300 or so and a little shipping . A head can be $30 + a piston, rings for $10  is literally $40 to my door including gaskets. ... appropriate for a $150 bike I suppose. For china bikes I'm think minimal investment IMO.

Thanks for advice, I will try the scotch brite pads probably and of course hosed down with breake cleaner before liberal lubing when assembling.
