The cylinder guides the piston and forms the combustion chamber with the head: a new cylinder kit restores top-end compression and power.
CYLINDER WORKS Ø97 mm cylinder kit for YAMAHA WRF 450, YZF 450 and FANTIC XEF 450 from 2020 to 2023.
The CYLINDER WORKS Ø97 mm CW20014K01 cylinder kit is designed for YAMAHA WRF 450, YZF 450 and FANTIC XEF 450 from 2020 to 2023. The cylinder guides the piston and, together with the cylinder head, forms the chamber where combustion takes place. Its bore coating wears, scores or goes oval over the hours: a new cylinder kit gives the engine back its original compression, or more displacement with a Big Bore version.
Specifications
- Brand: CYLINDER WORKS
- Manufacturer part number: CW20014K01
- Engine: 4-stroke
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.
Why CYLINDER WORKS?
Cylinder Works makes new, not remanufactured, cast-aluminium cylinders to the original design. The bore is electroplated with nickel silicon carbide and diamond-honed to exact size: an alternative to an OEM cylinder or a re-plate, with a forged Vertex piston matched to the cylinder in some kits.
