Communication
During the process I will keep you updated on the progress. I will use email, and I will create a Google Drive location and send you the access. There I can upload larger files such as pictures and videos.
Typical uploads include:
- As Found pictures of your carb bank
- Initial inspection report (see attached copy of blank report.)
- Carbs disassembled and ready for ultrasonic cleaning.
- Carbs after cleaning laid out to dry.
- Carbs ready for assembly.
- Assembled carb bank ready for test engine for balancing and tuning.
- Video of tuned and balanced carbs running on test engine. I run them from idle up to 2000, 3000, 4000, 5000, 6000, red line. Each time I snap the throttle closed, which produces maximum vacuum. If there was a leak it would backfire in the exhaust. This shows there is no leak. I snap the throttle to red line, and from 3500 or so to red line.
- A video explaining the use of the Digi Sync carb balance tool on the test engine.
- Final carb inspection report
- Any other pictures or information needed.
Information I need for tuning your carbs.
- Bike model (Standard, Tourer, Interstate)
- Type of Air Filter (Stock, or K&N or other high flow filter) Stock is recommended.
- Type of exhaust (Stock or aftermarket)
- If exhaust is stock, has it been modified. If yes, how was it modified? (Piggies cut, Baffles drilled, Baffles cut out.)
- If aftermarket, what brand?
- Are baffles in or out?
Exhaust mods that lower the back pressure significantly will require different jetting than stock. The additional jets will cost about $85 including Shipping, depending on the market at the time.
If I find broken or missing parts that require replacing, I can source new parts for you or sell you used parts for ½ price IF I have them.
If you need further assistance, please let me know.

What is Digi Sync service?
Digi Sync service is installing your carbs on my Valkyrie test engine, and using the Digi Sync tool to balance your carbs.
• The six carburetors must be balanced, or the engine loses horsepower and fuel economy.
• Digi Sync is an electronic 6 channel digital peaking manometer.
• With it, I can see all 6 vacuum signals at once and balance your carbs perfectly.
• Digi Sync is absolutely the best tool for balancing your carbs.
COLORTUNE uses a spark plug with a window into the combustion chamber.
• With the carbs mounted on the test engine, I monitor the color of the combustion with the Colortune plug and adjust the carb pilot screw to get an optimal combustion mixture.
• If the combustion is too lean it becomes light blue, and too rich becomes yellow.
• Since we have six cylinders, each with a dedicated carb, I repeat the test for each cylinder.
Exchange Option is for a carb set that I have on hand, already rebuilt and ready to ship.

If something is broken in your carbs, I will let you know.
If there is a need for extra money to cover unexpected costs (such as a failed air cutoff valve), we will deal with that separately.
It is rare, but if it happens. There is no way to know until I get them apart and test them.
Each grill is custom hand made in the US, Southport, NC.
It is constructed from architectural 6063 aluminum ½ inch bar stock and ¼ aluminum rods, and polished to a high shine.
6063 aluminum is more corrosion resistant. 6063 is primarily used for exterior railings, decorative trim, and door frames. It works out well for our radiator grill.
The grill is designed to mount on top of the stock radiator screen using the same mounting holes.
No modifications to your bike are required.
Stainless steel cap screws and washers for mounting are included.
Instructions also included.

The history of the grill.
The Blue and gold bike pictured with the grill is a 98 tourer that started out black. It was in rough shape when I bought it. Restoring it has been a labor of love.
I have had 2 Valkyries, and my sons, and sons in law all ride them. I think Valkyries are one of the most iconic bikes ever built.
Rivco used to make a 9 bar grill, but I couldn’t find one when I wanted it so I built the first grill for this bike, then family and friends had interest, so I decided to build some for other Valkyrie owners.
I am trying to keep them reasonably priced and still get some return for the large amount of effort that goes into one of these.
I hope you enjoy having it on your bike. Think of me the next time someone rolls down their window at a stop light and says “Wow, what kind of bike is that?”
Will my 7 Bar radiator grill tarnish?
The 6063 aluminum is resistant to tarnishing, and the polish also has a coating in it to preserve the shine.
When the grill leaves here it is shined to a high gloss. If you incurred any scuffs or scratches during installation, any good metal polish will shine it back up.
Use a microfiber rag, NOT paper towels. Paper is abrasive and will dull the finish.
When riding, bugs etc. will hit it. If the five-foot rule isn’t working for you, (standing back 5 feet and viewing it), polish it as above. ;-)
Enjoy how good your bike looks.
Yes.
The Custom 7 bar Valkyrie radiator grill fits all Valkyrie 1500 models for years 1997 to 2003.

About Us
About Us
Hi, I’m David Morgan. I created Valkyrie Carbs and Custom. I have 48 years of technical experience between the US Navy and Nuclear Power.
I spent 4 years in the United States Navy as a technician on attack aircraft weapon systems, com/nav, and RADAR systems.
After the Navy, I did an apprenticeship as an Instrument and Control Technician at a Nuclear Power plant, and worked as a technician in nuclear power plants for the next 23 years.
Following those 27 years as a technician, I became an instructor. For the next 19 years I trained the technicians who calibrate and maintain nuclear plant control systems.
Along the way, I also earned a Master’s degree in Theology.
I’ve been married for 48 years. We raised 4 kids. My 2 sons, and both sons in law also ride Valkyries.
I rode scooters and dirt bikes as a kid, and started riding street motorcycles in 1982. I had a 1982 Yamaha 650 Maxim, then a 1983 Honda Goldwing. I bought my first Valkyrie in 2000, a black standard, and became hooked on the iconic bike that was called the “Cruiser of the Decade.”
I currently have a 1998 Valkyrie Tourer that had been neglected in the coastal North Carolina area. I restored the bike from the ground up, and plan to keep it as long as I can ride.
I also have a 1999 Valkyrie Interstate Trike. The trike was owned by Bob Smith, Attic Rat, and he fixed it up with his special magic. He then sold it to Danny McMillin to extend Danny's riding when he was reaching the end of his life. When Danny passed, my sons arranged to get the trike for me for Father's day. It is a very special machine to me as I no longer can ride my Tourer. I always keep the rear pegs down in case Danny or any other of our fallen friends care to ride.
I got into rebuilding carbs because my carb fuel rails began leaking after a winter break, so I learned how to rebuild carburetors. Then a half dozen family members and friends needed carb work. Soon people wanted to pay to have it done, so Valkyrie Carbs and Custom was born.
I wanted a Rivco 9 bar radiator grill, but could not find one to buy, so I created the 7 bar grill using 6063 aluminum polished to a high shine.
We are now focusing on producing custom parts that are similar to parts that have become unobtainable at reasonable prices. We want the Valkyrie community to still have access to good custom parts at reasonable prices.
New products are in the works, so check back often to see what we have.
