This is our Cycle X crankshaft balancing chart to show how our crankshaft balancing is second to none. Check it out

Performance Notice: PVD coating process (NANO technologies) is one of secrets of the Cycle X vintage road racer.
This coating is used on rod bearings, main bearings, roller bearings, needle bearings, valve stems and anything that moves.
Sputtering this Moly disulfide coating will hold oils on the part, reduce friction, reduce heat and is great for long period sittings and cold startups.

 

 

This YouTube video shows how smooth a well balanced Honda CB750 can be. This particular motor had the crankshaft, alternator and clutch hub/chain wheel balanced.

 

 

Engine Case Main Bearing Alignment Repair
 

Ever notice Honda CB750 main crankshaft bearings have rub marks here and there in a random manner? Ever wonder why Eraldo Ferracci suggested to tighten the main bearing bolts in 2 lb increments checking for a binding crankshaft and recording the torque figure at bind?

We applied blue dye to the engine case main bearing bores to exaggerate our observations years ago for photo purposes.

After applying the blue dye for photo purposes, we inserted our special machined alignment tool, torqued the main bearing bolts and rotated the tool. This procedure exposed tight areas, barely visible nicks in the main bearing area and possibly slight warpage.


Due to the fact that Honda main bearing clearances are generally in the .0015 to .002 range and Plastigage gauge measuring is a crude form of measuring in many circles. This sends up a few red flags about crankshaft alignments. Line boring the cases is not an option because of oversize bearing availability.

The 2nd photo (hard to see) shows these random rub marks with .002 Plastiguage clearances. To help with this potential problem is to remove the high spots, nicks and such ONLY with our special tool and procedure. After the crankshaft is reinserted in the cases and torqued, the crankshaft spins noticeably easier.

Happy motor!

Refurbished Chain Wheel Cush Drives and Balancing

Note: Before we go any further with our explanation of cush drives and rebuilding cush drives, we must mention that Honda has not offered these parts for years. Secondly, most racers and people that are desperate for a fix will use "O" ring material sold in bulk and cut it to size. The trouble with "O" ring material sold in bulk is the fluctuation of the outside diameter and the rubber quality itself.

Note: It is not uncommon for the outside diameter of "O" material to fluctuate .030 or more. Introducing the Cycle X Nitrile blended molded cush drive rubbers with 85 +/- Durometer hardness.

 

This addition to our refurbished Honda CB750 section is something that many people are aware of, but sometimes ignore. Meaning, the cush drive rubbers on the inside of the hub that are disintegrated about 50% of the time. Call it father time or they just lead a hard life.

So here is what we do...

We disassemble 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.
The cush drive is now assembled and ready to go.

By the way...
Like crankshafts and alternator rotors, the cush drives and outer steel clutch hubs are not balanced.

As an option, we are also offering balancing the cush drive and outer steel clutch hub as a unit.

Because real life story's are sometimes better than written words. Our Honda CB750 vintage heavyweight super-bike road-racer had this same cush drive process done to it in 2012 and the motor is still together and running strong after all these years. The bike was sold and is still racing in Ireland.

Thermo Barrier Coating

We are reintroducing or reminding the public about thermo barrier coatings for pistons and combustion chambers. This is the same coating used on our vintage heavyweight super bike (AHRMA) which had remarkable long intervals between tear-downs. 

Here's one of my favorite tests from years ago...
   
The dome coatings in particular were tested on a hot rod v-twin motor (Harley) that started when the owner was super skeptical about the claims of thermo barrier coatings.

Here's what he did...

The front cylinder piston was uncoated. The rear cylinder piston was coated with the above mentioned process. During the running process, the heat sensors showed the rear cylinder 65 degrees cooler. True story. We have noticed the benefits of these coatings many, many years ago and have decided to stock thermo barrier pistons and cylinder heads for the performance minded.

Piston coating: $139.00

Combustion chamber coating: $139.00

Call to order.
