Thin Head Gaskets

An easy way to increase compression ratio a tad is to install thinnner head gaskets. A snappier exhaust note and a more efficient combustion can be expected.

Example: using a .030" head gasket in lieu of a .045" will increase compression by approx. 0.25 points. So if your CR with a .045" head gasket is 9.6, the static CR will increase to 9.85 with a .030" head gasket. Valve to piston clearance must be checked where appropriate.

Cometic Gaskets

AFM

Compounded nitrile synthetic rubber bonded to an aluminium core. AFM is the ideal gasket for machined surfaces like primary, gear case cover, cylinder base, rocker boxes etc.

MLS

Multi-Layer-Steel - 2 thin Viton-coated steel layers enclose an inner steel layer. Definitely a high-end head gasket. Spring Steel stainless steel core with Viton rubber-coating on both sides. The top notch MLS gasket technology is used with head gaskets only.

SLS

Single-Layer-Steel - one thin Viton-coated steel layer. The perfect cylinder base gasket.
