Featured Product #1:

"Billet" Cycle X 890cc 12.1 Piston and Sleeve Kit, 69-78 "K" Models
Back in stock.

We are proud and excited to release these Billet Wiseco pistons with our race proven Cycle X domes.

Why Billet?
Without blanks or forgings to achieve the race proven dome configurations, the pistons needed to be billet and built from scratch.
Secondly, Billet pistons can be machined on the undersides to reduce even more weight and run shorter wrist pins.
Conclusion, world class pistons for your five decade old hot-rod Honda.

Honda cb750 sohc models seem to love this bore size with or with-out port work with great reliability
These kits are commonly used with slight combustion chamber modifications  and camshafts similar to the CX-11 for best results.
Depending on the year or combustion chamber modifications the compression ratios are in the 11.5 ish to 12.5 ish range. Your camshaft selection, milling, chamber modifications and gasket thickness will affect or alter these compression ratio figures.

Why Cycle X sleeves?
Our cylinder sleeve are denser, harder and longer wearing than any sleeve on the market. Most machinists can hear and feel the difference when boring/honing the cylinders.

Note: Cylinders will require re-sleeving.

These pistons have a bare weight of 173 grams and have a Armor Glide skirt coating, tool steel wrist pins, XA ring sets, .00190 piston to cylinder wall clearance, and larger and deeper valve pockets for big valves and big camshafts.

The Cycle X Refurbished Chain Wheel and Outer Clutch Hub Details:

We disassembled the cush drive and glass bead for inspection. The inner portion of the hub is drilled and tapped for screws to replace the long rivets installed by Honda to hold the drive together.

Before installing the new cush drive rubbers, we measure the amount of deflection or wobble the two sprockets have. Most hubs have different measurements. But, they generally deflect or wobble over 2mm measured by the outer tooth area, relying on the cush rubbers to keep things somewhat stable. With that said, we surface the outer plates and machine the inner portion to reduce this deflection and wobble.

Before we install the specific length and material cush drive rubbers, we remove and install (2) new needle bearings on the inside.
We like to use later model clutch arrangements and will also fit in earlier motors.
This chain wheel and clutch combo has been refurbished as described above with inner clutch hub oiling modifications.
The chain wheel and clutch assembly combo is then balanced to absolute perfection. (1/2 gram, 1 in. from the center line)
