SO WHAT IS UNDERCUTTING?
Undercutting: Angular cutting of engagem
ent
dogs to keep from slipping out of gear.
Race Cut:
Undercutting
with slight ramps cut on face of engagement dogs to allow
smoother transition
in gears with less kill time if using an air shifter. Good for
street/strip use
SO WHAT IS SUPER FINISHING?
The REM'S ISF Process is an
isotropic surface finishing process that produces a non-linear, low Ra finish
that improves wear properties and reduces friction.
SO WHAT IS CRYO TREATING?
1. Greater
durability: Cryogenic treatment helps to promote the transformation of retained
austenite present in heat-treated steels into harder martensite steel. This
results in fewer imperfections and weaknesses in the steel's grain structure.
2. Improved wear resistance: Cryogenic
hardening increases the precipitation of eta-carbides. These are fine carbides
that act as binders to support the martensite matrix, helping to resist wear and
corrosion resistance.
3. Stress relief: All metals have residual
stress that is created when it solidifies from its liquid phase into a solid
phase. These stresses can result in weak areas that are prone to failure.
Cryogenic treatment can reduce these weaknesses by creating a more uniform grain
structure.

The Perfect Honda CB750 SOHC Transmissions.
New proven undercutting procedures.
We have reduced the undercut angles to 2 degrees resulting in better
shifting for street, road race and drag racing.
We also undercut both sides of the male/female dogs for acceleration
and deceleration improvements.
Our new machining set-ups and procedures are quicker and extremely
precise.
Our favorite transmission package: (above right)
Closer ratio transmission option. (perfect for road racing)
2 degree cuts on 2nd, 3rd and forth gears (both sides)
(6) transmission bearings.
Upgraded super finished shift drum. (super important)

Couldn't be happier with the quality and ratios."

Transmissions Identification Early & Late
In order to have a good operating transmission, you will
need a good operating clutch.
There should be no debate on the benefits of a under-cut
transmission.
Statements like "It's harder to shift or get the
transmission out of gear when shifting" only makes sense
if the gears are under-cut with severe angles or the
clutch is not operating correctly.
