ATHENA cylinder kit for YAMAHA DT 125 from 1991 to 2004.
On YAMAHA DT 125 from 1991 to 2004, the ATHENA P400485100019 cylinder kit fits in place of the original part. A cylinder that is scored, oval or has a damaged coating loses compression and wears pistons out quickly. Rather than having it rebored and recoated, this kit replaces it with a new, ready-to-fit cylinder.
Specifications
- Brand: ATHENA
- Manufacturer part number: P400485100019
- EAN code: 8052204292523

When to replace it?
- Cylinder scored or coating flaking after a seizure.
- Ovality or taper out of tolerance when measured with a micrometer.
Measure the cylinder at every piston change. As soon as it falls outside the tolerances in the manual or is scored, it has to be replaced or reconditioned.
Fitting tips
- Carefully clean the top of the crankcase and cover its opening before removing the old cylinder.
- Oil the supplied piston and check the ring end gaps before fitting the cylinder.
- Use new gaskets, either those in the kit or a suitable top end gasket kit, and tighten the cylinder and head in a criss-cross pattern to the manufacturer's torque.
- Fit a new spark plug and refill the coolant.
- Break the engine in gently for 3 to 4 hours, as Athena recommends for its cylinder kits.
