Concord, Ohio based manufacturer Cometic Gasket
has released new stock replacement and big bore
gasket and cam change gasket kits for Harley’s M-8
touring engines.
Because there are currently two very different
cylinder head designs offered on the M-8, Cometic
is releasing a number of different gasket designs.
One version of the M-8, the one used in Touring
models with no lower fairings, features oil cooled
heads. A second M-8 cylinder head version, this one
found in Touring bikes with lower fairings and with
radiators behind them, has provisions for that
coolant to flow through the heads, and Cometic say
they have gaskets for both, in sizes ranging from the
stock 107 and 114 cubic inch displacements to a big
4.500 inch big bore size.
All told, there are nine different cylinder head gaskets
in this M-8 line-up, along with new base gaskets and
the full cam change kit. Sales Director Jason Moses
told AMD: “While the differences between all those
gaskets are small and subtle, they’re critically
important.
“The oil cooled heads, the ones on bikes without
lower fairings, have one “teardrop” shaped port
close to the bore, and that is surrounded with an
embossed surface. With this head design the M-8 big
bore is limited to 4.200 inches with no modifications

to the heads. Any larger than that
would require the oil port to be
welded shut and the
head resurfaced.
