I’m givin this piston kit 5 stars cuz I put it in my raptor 350 a few weeks ago and it’s runnin great. The install was easy nuff I did it myself, the piston seems sturdy with the heat treatin and moly coat, it improved my raptor’s performance for trail ridin, runs smooth no issues, customer service was real helpful too, I’d recommend this kit if your engine’s gettin tired, nice upgrade for the average joe.

this piston kit is a decent replacement part for most yamaha raptor and warrior models, with quality construction and performance though my experience has been neither fully positive nor negative

This piston kit is a good quality replacement for older Yamaha Raptor and Warrior models, with improved durability from the heat-treated piston and faster break-in from the special coating it’s worked well for me and most other buyers seem satisfied too.

This affordable piston kit gets the job done for budget builds or as a temporary fix, but for peak performance and a smoother, quieter ride, enthusiasts may want to invest in a premium kit with tighter tolerances and higher quality coatings.

The piston kit includes main components but the basic instructions left me unsure at times. While quality seems good the performance gains were modest and the coating didn’t increase longevity during my testing.
