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)
(3) super finished shift forks.
Note:
Most early, late and closer ratio transmissions will be in stock
shortly.

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.
