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)

The Oil Pump Rebuild Kit, Complete.
Who has the best oil pump kits?
Cycle X has the best kits!

These oil pump kits are endorsed and used by top engine builders worldwide.

Note: Stock pressure relief springs are known to dump oil too soon and show low pressures when springs get old and in racing applications.
Many people would add shims to the springs and boost the pressures a bit when needed.
Our Cycle X kits are the most complete kit in the industry and also have
8% stronger pressure relief springs.
Our kits also have the discontinued OEM center oil seal that the other kits are missing.

  Kit includes:

Oil pump rubber stopper.
     Prevents oil from entering the motor from the oil tank when not running.
Oil pump stopper spring.
     New is good.
Pressure relief spring. (8% stronger)
     Important to keep oil pressure up instead of dumping off into the crankcase.
Oil pump screen.
     Hard not to damage these screens when disassembling the pump.
Oil pump o-rings.
Oil pump mounting o-rings.
Oil pump screws.
     Nice and new for reassembly.
Oil pump center oil seal.
     Honda OEM seal, not pictured.
