These are new cams with no core required. Note that J-Models
and GPZ1100s with the hy-vo style chain must use APE cam sprockets

in KZ-type heads, and most GPZs. |

TITANIUM VALVE SPRING
RETAINERS
APE valve spring retainers are machined
from aircraft quality titanium bar stock in the APE plant on
the latest state of the art computerized CNC machinery.CNC machining
allows us to offer such advantages as bored taper keeper holes
for exact keeper fit. Special gauging fixtures allow dimensions
to be held close to provide exact installed heights when assembling
the cylinder head.
APE titanium retainers are shorter than stock to provide additional
retainer to valve guide clearance for high lift cams.
APE is the only manufacturer of motorcycle retainers that also
builds cylinder heads.
We know how they have to fit, how they have to clear the bucket,
etc. No other manufacturer can offer this expertise.
You might think this extra precision is expensive.The fact that
we are the manufacturer allows us to provide these super precision
retainers at a price everyone can afford. See the chart above
for applications.
NO MATTER WHO BUILDS YOUR CYLINDER HEAD, INSIST THAT THEY USE
APE TITANIUM RETAINERS.
TVSRK1000 Shim on bottom retainers, set of 8 - $149.95
TVSRK1000-600 Shim on bottom retainers, set of 8 (Fits Manley
/ PSI Pro Stock Springs) - $158.39

SHIM-UNDER TAPPETS
APE tappets locate the shim under the
tappet to eliminate the possibility of the shim being spit out
of the cylinder head. This is a must with cam lifts over .420
in a Kawasaki. APE tappets require use of APE titanium valve
spring retainers.
