sumit highmark 800 HO week cylinder

[Pinebeatle]

Hi there people, I got a 2003 sumit highmark 800 HO with a week cylinder - Compression test 130 one cylinder - 90 on the other. I am comfortable doing the work myself but would like to know if i should do both cylinders or just the bad one? Should I replace pistons and rings or just rings? Is their some sort of coating on the cylinder walls that need attention? OEM or aftermarket parts? So many questions. LOL But I figured I would ask the experts here! Thanks Guys

Do both. Save yourself some work in the long run. Replace the pistons with dual ring pistons.
