Zenoah Fujiwara 40mm High Compression Piston (0.8mm ring) [FJK352002HP]

Fujiwara continues to push out for more power from your Zenoah G320RC. This high compression upgrade piston is designed for those using the 40mm Bore Up kit. Featuring a friction reducing coating this has a ring land for use with a 0.8mm thick piston giving you as much RPM as possible.

For those seeking a more durable piston and ring you can use the 1mm ring FJK352001HP High Compression piston.

We have also made a detailed installation video showing the entire installation of the Fujiwara 40mm Bore Up kit that can be viewed HERE.
