SO WHAT IS UNDERCUTTING?

UNDERCUTTING: ANGULAR CUTTING OF ENGAGEMENT
DOGS TO KEEP FROM SLIPPING OUT OF GEAR UNDER LOAD.

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.

Super finished/Under-cut complete transmission.
These super finished transmissions are beautiful to look at and are possibly better than coatings.
Slick shifting, added horsepower, far less friction and less generated heat.
Under-cut 2nd, 3rd and 4th gears insure that your bike will never jump out of gear. 1st and 5th gears are generally not needed to be under-cut.
Note:
This transmissions gear ratios are considered early.

Includes:
Mainshaft.
Layshaft.
Shift forks.
Late upgraded shift drum.
(2) OEM mainshaft bearings.

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.

970cc (70mm) Refurbished Piston & Cylinder Kit

This piston and refurbished cylinder are fully machined and ready for installation.

The cylinder is the preferred early version with out the 8 large drain holes that are not able to be used when big-bore sleeves are used.
The cylinder fins are nearly perfect.

The cylinder has been re-sleeved in the following manor:
Glass beaded for inspection.
Stock cylinder liners removed.
Alloy cylinder is skim surfaced on both sides.
Alloy cylinder is bored to approx. .007 final size.
Epoxy is applied to open cavities when large cylinder liners are used.
"O" ring grooves are re-machined on the bottom.
The cylinder is final bored and honed to accept big-bore sleeves.
Note: Many machine shops in the olden days would only bore the alloy block and push the big-bore sleeves in. This procedure never really seemed to work because the alloy block had boring bar machine marks left and the sleeves would loosen in time. That's why boring then honing to exact sizing and finish are important.
The cylinder is heated and cooled cylinder sleeves are installed.
Cylinder top is re-surfaced.
The cylinder is now final bored and honed.
Six heli-coils are installed (we like heli-coils).

The 70mm 970cc Wiseco pistons have generous valve pocket reliefs and accept oversize valves. Compression ratios range from high 10's to mid 12's depending on combustion chamber modifications.
Armor glide skirt coated.
Thermo barrier dome coated to repel unwanted heat.
XC ring package.

The cylinder sleeves are the super dense and harder than most cast iron sleeves on the market. Most machinist can hear and feel the difference when boring and honing. Our sleeves are better!
