Always utilize a dedicated crankcase separator tool. Additionally, take your time when checking the ring end gap inside your freshly prepared cylinder bore before installing the rings onto the Vertex piston—proper gap clearance ensures maximum compression and prevents ring binding at peak temperatures.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/search?q=Honda+CR125R\"\u003eShop Additional Honda CR125R Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/search?q=Maxima+2+Stroke+Oil\"\u003eShop Premium 2-Stroke Premix Oils\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/search?q=Engine+Case+Splitter\"\u003eShop Specialty Engine Pullers and Crank Case Tools\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX\u003c\/b\u003e\u003cbr\u003eYour Premier Motocross \u0026amp; Powersports Specialist\u003cbr\u003eServing Clermont, Montverde, and the Greater Central Florida Area\u003cbr\u003eAvailable for Fast Shipping Nationwide or Convenient In-Store Pickup.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":40566438363219,"sku":"WR101-100","price":605.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1754\/5421\/files\/vertex-wrench-rabbit-engine-complete-rebuild-kit-wr101-100-2005-2007-honda-cr125r-702293.jpg?v=1735463353","url":"https:\/\/motohousemx.com\/products\/vertex-wr101-100-complete-engine-rebuild-kit-2005-2007-honda-cr125r","provider":"Moto-House MX","version":"1.0","type":"link"}
