JE 685 Piston Kit - With cut head gasket

Fits: 1996 - 2018 Kawasaki KLR650

Part number: 685pk


Description:

This is the most advanced piston available for the KLR! Gas ports for the top ring, piston lighter than others, broached slots in the wrist pin hole for improved oiling, updated second ring design for oil control. Tightened up tolerences on the ring grooves and acumulator groove to eliminate ring flutter and wear. Premium ring set. The stock ring, piston, wrist pin and circlips weigh 640 grams. This exclusive piston kit weighs 490 grams. This engine setup is much smoother than stock.

Oversize piston kit, fits 1996 and later KLR650. Forged, lightweight, 2.5mm over stock. Premium rings and wrist pin. Requires cylinder machining. This kit includes a cut head gasket. Lighter and smoother than the factory setup. If you have an oil user this is a good way to go.

Improved performance and smoother engine. Much greater difference than expected for a 34cc increase.

We are supplying an OEM Kawasaki head gasket that is cut for the oversize bore.

We highly recommend installing a ThermoBob on every KLR650, especially those with a big bore kit. This helps the cylinder stay round.


IMPORTANT - these are considered racing parts, and there is no warranty. The performance and function is entirely dependant on the quality of the bore and honing, and install process.
