Honda CB750 F2, F3 Valve Spring and Retainer Combo
These Cycle X, Kibblewhite valve springs are the
favorite around here and with many pros worldwide. They
are used exclusively when high-lift cams require valve
sinking for valve to valve clearances. The reason these
springs are used is they will not require piles of
spring shims to get desired pressures.
So, stock valve spring installed height (1.455ish)
spring pressures with Cycle X, Kibblewhite ENV-009
springs are:
85lbs (no shims)
90lbs (.015 shim)
105lbs (.060 shim)
75lbs with .030 sunken valves (K & F models)
Caution:
Honda
CB750 77-78 K's and especially F2's have the potential
of the keepers pulling through the top spring retainers
and dropping the valve into the motor. Many people have
felt this heartbreak for the past 30+ years. Honda's
later model spring retainers are stamped steel, combined
with a steep keeper angle, has only been addressed by
complete spring kits costing hundreds of dollars, until
now.
We have
been working with Kibblewhite and have developed these
top retainers to cure this problem once and for all at a
reduced cost. Heat is a
problem in the F2 valve tranes, these new lightweight
top spring retainers feature 8 holes on the top of the
retainer. The purpose for these holes is to allow oil to
drip down the springs to help with heat dispersion. Keep
in mind, oil lubricates, picks up heat and carries it
away to coolers and such. People in NASCAR use the same
technique and it helps keep the valves well lubricated
for longer life. These retainers are made from heat
treated carbon steel for durability and strength. 11.25
grams per retainer!
