5 of 5 Noticable difference January 3, 2024
Reviewer: Steven T. from Barksdale AFB, LA United States  
Needed to do a piston swap to fix damage and get a frag top end, so went with the popup. Noticeable gain in compression, throttle response, and torque. Circlips were tuff to get in but otherwise, well designed and manufactured. Fast shipping!

5 of 5 Good fit, wrist pin clips are tough! November 30, 2021
Reviewer: JTR from Fallon, NV United States  
Fit oem cylinder, piston wrist pins are tough to get in.  Be nice to offer clips in case someone looses one.  Saw started right up and has ran through one tank of fuel.
