LA SLEEVE cylinder sleeve for YAMAHA WR 426 F, YZ 426 F from 2000 to 2002

LA SLEEVE offers this cylinder sleeve for YAMAHA WR 426 F, YZ 426 F from 2000 to 2002. The sleeve is the wall the piston moves up and down in. When it is worn or scored, it can be replaced in the original cylinder instead of buying a complete cylinder.

Why re-sleeve a cylinder?

The benefits:

• Save a cylinder that is scored or worn beyond its last oversize.
• Cast iron allows several rebores later: an oversize piston can be fitted at the next rebuilds.
• Often cheaper than a new cylinder.

Why choose LA SLEEVE?

L.A. Sleeve has been sleeving cylinders since 1945: its sleeves are centrifugally cast from a chrome-molybdenum alloy, hard and wear-resistant.

When should you replace the cylinder on your YAMAHA YZ 426 F?

A scored or oval cylinder, or one with damaged plating, loses compression and wears the piston quickly. Measure the bore at every top-end rebuild: beyond the wear limit the cylinder must be replaced or resleeved.

Specifications and fitting tips
