A cylinder to suit the DLE 120 twin — a large two-stroke petrol engine for big scale models.
On this engine the component is the cylinder, which forms the bore the piston runs in and carries the transfer and exhaust ports on a two-stroke.
Why this part matters: a scored or oval bore is the reason to replace a cylinder rather than just the ring, and cylinders also suffer damage from a lean run.
Fitting note: Measure the bore at several heights before condemning it, and check the port edges for burrs.
