This CILOYU kit supplies a 70 mm flat-top piston plus pin, rings, gaskets, valve springs and a spark plug so you can complete a routine top-end rebuild in one purchase. The components are corrosion-resistant and manufactured for consistent fit and function with Predator-style 212cc and 224cc horizontal single-cylinder engines.\u003c\/p\u003e\n\n\u003ch3\u003eWhat exactly comes in the CILOYU 70mm piston kit?\u003c\/h3\u003e\n\u003cp\u003eThe kit is comprehensive so you won’t need multiple orders to finish a top-end rebuild.

The CILOYU 70mm flat-top piston kit is intended for DIY mechanics, small-engine repair shops, and riders who need a dependable replacement for Predator 212\/224 or compatible GX-series engines. Buy this kit if you need a complete top-end repair package with piston, rings, gaskets, valve springs and ignition plug in one box, and if you can follow basic engine assembly steps—especially proper ring gap staggering and torque sequences. If you aren’t sure about bore size or installation steps, consult your engine manual or a qualified technician before fitting the parts.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this piston fit my Predator 212 or 224 engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—this kit is made for Predator 212cc and 224cc engines and compatible GX160\/GX200 variants with a 70 mm bore.
