The CB190X uses a roller rocker arm valve train. It is durable, but the intake and exhaust clearances are tight (typically 0.12mm–0.18mm). Without the service manual, you won’t know the specific cold-engine clearance. Set them too tight, and you burn a valve; too loose, and you get a top-end rattle that sounds like a diesel truck.
