The Cometic C3790 90mm Top End Gasket Kit is designed for reliable engine sealing and improved low-end performance on select KTM and Husqvarna 350 models. This kit raises compression to help enhance throttle response and low-end power while providing the sealing integrity needed for top-end engine service. It is engineered for powersports applications and offers a practical replacement solution when rebuilding or servicing the cylinder, cylinder head, and related top-end components.
Each gasket is manufactured with materials selected for durability, flexibility, and torque retention. The graphite gaskets use a steel core laminated on both sides with flexible graphite, helping maintain a dependable seal through repeated heat cycles. Fiber gaskets are designed for maximum sealing performance, flexibility, and torque retention, while the O-ring gaskets meet or exceed OEM specifications. The 90mm size is matched to the specified engine application for proper fitment and installation.
This Cometic top-end gasket kit fits 2019-2022 KTM 350 SX-F models, 2019-2020 KTM 350 XC-F models, the 2020 KTM 350 EXC-F, and 2019-2020 Husqvarna FC 350 and FX 350 models.
