The Cometic C3144-EST Top-End Gasket Kit is designed for Yamaha 700cc performance and replacement applications. Featuring a 105.5 mm bore size, this kit raises compression to help improve low-end power while providing the sealing performance required for dependable engine operation. The kit is manufactured by Cometic and is identified by manufacturer part number C3144-EST and vendor part number 68-31440E.
The gasket materials are selected for durability, flexibility, and torque retention. Graphite gaskets use a steel core laminated on both sides with flexible graphite, helping maintain a reliable seal under demanding engine conditions. Fiber gaskets are designed for maximum sealing performance, flexibility, and torque retention, while the included O-ring gaskets meet or exceed original equipment manufacturer specifications.
This Cometic top-end gasket kit fits the 2013–2017 Yamaha YFM700 Raptor and the 2007–2011 Yamaha YFM700G Grizzly Fi 4WD with independent rear suspension. It is suitable for service, rebuild, and performance-focused engine work when a properly matched top-end gasket set is required. Verify the vehicle model, year, bore size, and engine configuration before installation.
