Gaskets – It was not possible to use an OEM head gasket with the JBS Racing “750” or “700” kits. The deck height on the Husaberg engine is almost zero so if a head gasket is used that has a smaller bore than the piston being run the piston will hit the rolled steel lip of the gasket. This is the case weather you are running a JBS Racing 105 / 108mm piston or another kit such as one running a 103mm piston.

Initially we were using Aluminium or Copper soft-metal gaskets as these were relatively cheap to produce and did not require the high tooling costs of custom gaskets.

Our method of sealing required very flat heads and cases, excruciating cleanliness and meticulous assembly. It worked Ok but only if all these things were done right. So we decided that we need to have an OEM style fibre gasket made to make the engine easier for the average racer to put together. We now have custom made JBS Racing fibre head gaskets available in 105mm & 108mm bore. At the same time we decided that we would have after-market gaskets made by our supplier for every other gasket on the Husaberg engine, these are also available from JBS Racing for less than OEM parts.
