CNW Modifications
Colorado Norton Works can make your Norton motorcycle run smoother than ever and look better than you could imagine thanks to our complete modifications on rear hubs, transmission seals and oil tanks. While our services will create an eye-catching bike, it will also help protect your custom built motorcycle against wear and tear.

   Rear Hub Modification
Motorcycle Wheels.gif
Motorcylce Hubs.gif		 Description:
Don't spend your money lacing up that nice looking new rim and spokes on that sorry looking old hub. Send us your old hub and let us modify it to an exceptional finish before building your new wheel.

The rear hub is machined down in the center and on the outside. The small fins are retained and that surface is bead blasted for an easily maintained finish. The outer lips are show polished. Included in the upgrade are 2 sealed single row bearings.

We already have hubs that are machined and ready to go on an exchange basis so your turnaround time is short. The hubs that are ready to ship are 'cush drive' style. If you choose to have us do the work on your 'cush drive' hub or if you have a 'bolt up' hub we can do that as well. It will take a little longer for you to get it back. Contact us for actual time.

Complete hub: Machining, blasting, polishing, sealed single row bearings (2)

   Transmission Seal Upgrade
Motorcycle Transmission Seal Description:

#1702-P
Our Price: $146.00 (seal upgrade + polish)
- Same service as above but we will completely sand and show polish the cover as well so it's ready to install. The bolt coves are also machined for a finished look. Many of the alloy Commando parts and the Transmission covers in particular have a lot of casting flaws that show up like little dimples. These will not disappear with the polish. The cover will be as perfect as it can get given the core quality.		 b_contact_us.gif

   Oil Tank Modification

Norton Commando Oil Tank Description:
Send us your old oil tank and we will do a number of upgrades and modifications to improve on the original design. The original upper mounts fail and when the lower mount gets over loaded it will fracture the tank. If you are fortunate it will only create hairline cracks and the tank will just leak, if you aren't so fortunate the entire mounting boss and part of the oil tank will come off and the oil will pour out (on your rear wheel to make it all worse) and in a matter of seconds your oil tank will be completely empty. Your sweet old Commando engine is now running without oil and it won't do that for very long.
This is what we do to your old tank:
    - The oil tank gets completely boiled out to remove any sludge and build up. This also strips all paint off.
    - The lower tank mount gets cut off and a plate is brazed over the area to ensure any hairline cracks are covered up.
    - The rear mount is beefed up for added strength.
    - The spigot to the chain oiler (if equipped) is closed up
    - The oil tank gets a gloss black powder coated finish.
    - The finish is removed where needed to ensure proper sealing when installed.
    - Included are two rubber mounts that are far stronger than the original.
    - Stainless steel hardware to mount is included.
    - A high density foam pad to install between the battery cover and oil tank is included
    - We have some tanks on the shelf ready to go so the turnaround is fast. We just need your old tank as a core.

   CNW Head Services

Norton Commando Oil Tank Description:
Work performed by CNW and Comstock Engineering
Exhaust Port Repair
If you have poor exhaust threads we can repair your head once and for all. This exhaust thread insert is a cold install rather than welded in. The welded inserts, because of the heat applied, have a tendency to distort the head which can lead to a number of problems. Rather than putting the head through the stress we machine out the port thread and install our machined aluminum/bronze insert. The installation is permanent. Because of the properties of the aluminum/bronze, it has less tendency to gall and it aids in installation of your exhaust nuts. We still recommend using a lubricant to ensure proper seating. If your head has a weld-in insert we can most likely still repair it with our insert but we need to take a look at the head before proceeding. Call us for additional information.

#1706
Our Price: $157.00 per port

Head Surfacing
We will run the head through on a mill to ensure that the gasket surface is perfectly flat. This is an often overlooked service and most heads are in need of more or less surfacing for correct gasket contact.

#1707
Our Price: $42.00

Equalize combustion chambers
We measure the actual volume of each chamber in the head and mill them to ensure that they are identical. This not only affects proper valve train geometry but also the compression.

#1708
Our Price: Starting at $84.00
