There are lots of facts regarding the gasket of the headre of the Kawasaki Ultra Supercharged engines. It is the Achilles ptern of the exhaust system since at high exhaust pressure expecially in race condition its sealing properties are getting less. This particular aftermarker triple layer (multi layer steel) gasket promises better sealing accoring to the seller. However, it was tested on a brand new Kawasaki Ultra 310 LX with only 20 hours of use and it was found that the sealing of the header was not improved but got worse than using the oem gasket. It is worth noting that the surface of the exhaust manifold and the header were both cleaned through out before the installation of the new triple gasket. Photo courtesy: Jetskiworld.gr
