### ⭐⭐⭐⭐⭐ Beast of an Engine – Revived My ATV Like New!
*by S***N on June 20, 2025*

This CG250 engine is pure reliability! After installing it on my 2008 dirt bike, the difference was night and day – starts first pull every time (even in cold weather) and the 5-speed transmission shifts buttery smooth. The vertical design saved me hours of installation hassle compared to horizontal engines. I've put 200+ hard trail miles on it, and it still runs cooler than my old engine ever did. The torque is perfect for hill climbs, and fuel efficiency surprised me (about 30% better than my previous motor). Comes with all necessary mounting points for ATV conversions. A steal for this quality!
