This cylinder has been fully machined with big bore sleeves installed.

Includes: Glass beaded cylinder, remove sleeves, surface bottom of block, bore and hone block and install sleeves, surface top, bore and final hone.

The cylinder has nearly perfect fins and is a early version which is preferred when using big-bore sleeves.

170 bare weight grams.
Wiseco XC ring sets.

These pistons have deep valve pockets and will accept larger valves.
Depending on your combustion chambers modifications. High 10.1 or 11.1 compression ratios would be normal.

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!
