Frequently Asked Questions

Which engine joint does this gasket seal?

One gasket cross-referenced to Honda OEM 11395-425-306 seals the left crankcase or generator cover on the compatible Honda CB engines.

What should be checked before installing the new gasket?

Remove the old gasket without gouging the aluminum, clean and inspect both mating surfaces for damage or distortion and confirm all dowels and oil passages are correctly positioned.

Should gasket sealant be added during installation?

Follow the Honda service procedure for the specific joint; do not add excess sealant that can squeeze into the engine. Tighten the fasteners evenly to the specified torque.
