Derby cover with 3 mounting holes for Harley-Davidson Shovelhead and Evolution big twin models.
The base part is machined from A6061 aluminum alloy.
Goldfish and 2 gears on the surface of brass plate are realized by etching.
Etching differs from printing. Watching the surface carefully, you will notice the convex and concave figures.
Brass plate is fixed to aluminum body with 8 rivets.
The following picture shows installation example. The derby cover is put on the Shovelhead FLH primary cover.
Mounting bolts are not included.
I will release new products Point Covers at the end of August 2020.
There are 4 types of point covers.
1. 1986 FXRD Grand Touring
No explanation is necessary to describe this point cover. I dedicate this point cover for fanatic fans of Harley-Davidson FXRD.
2. 8bit Digital Ignition
What remarkable is the development of technology. Maybe the time has come to update your ignition system from old point ignition to the latest digital ignition.
Please never forget putting this point cover on your motorcycle when update is done.
3. FLH with checker flag
One of the most popular and iconic name in the series of Harley-Davidson motorcycles is “FLH”, isn’t it?
This cover represents the honor of the king of motorcycles.
4. The age of the Aztec
There was a kingdom in the old days. It was called Aztec empire. That’s all.
These point covers are mainly made of A5056 aluminum alloy, etched parts are brass plates.
Every brass plates have adhesive tape on their back.
Two #8-32 mounting screws will be included.
I established “Point Covers” page.
The status of the product will be changed from “out of stock” to “order now” when I start the sale.
We are surrounded by many information, however, useful information in a true sense are few. It’s worth for the people who eager to know the internal combustion engines, especially Harley-Davidson V-twin, reading these books. The author D. William Denish tells us in his books the mechanism and function of each parts in plain terms.
I bought and read his three books, “V-twin Tuner’s Handbook vol.1”, “V-twin Tuner’s Handbook Vol.2” and “Big Twin High-Performance Guide Vol.1”.
The only thing is, I can’t find “Big Twin High-Performance Guide Vol.2”. In the end of “V-twin Tuner’s Handbook” it says that “Big Twin High-Performance Guide Vol.2” will be published in 2000.
ISBN code is also written. I have looked for everywhere on the internet. But I couldn’t find the book. I tried to contact Crystal Publications which is the publisher of those books, however, it turned out to be a complete failure. It seems the publisher is no longer exist. What happened to Crystal Publications and “Big Twin High Performance Guide Vol.2”?
The author D. William Denish wrote in his book “Big Twin High-Performance Guide Vol.1” that he was going to mention about bottom end parts in his latest book “Big Twin High-Performance Guide Vol.2” and that is the information what I’ve wanted to know for a long time.
It says “Big Twin High Performance Guide Vol.2” will be available in 2000.
Almost all the people can explain that how intake, exhaust and ignition system affect performance of the V-twin motors to a greater or lesser extent. Nevertheless, there are few people how the crank and flywheel affect the performance and durability of the V-twin motors. William Denish explains various factors we should consider when we manage to modify internal combustion engines with many examples or visual information like graphs and tables.
His explanation is easy to understand.
Sometimes these kinds of books introducing how to modify V-twin motors tend to be catalogs of parts maker. But his books are differ from those kinds of books.
Internal combustion engines are not set of many performance parts. Only gathering and piling up performance parts are not enough to make true performance engines. The fundamental knowledge is necessary and we can find them in his books.
Until now the material of Tank Dash Cover and Floorboard Inserts have been only brass plate. This time I added another version of those products. They are made of stainless steel.
The pattern of the surface is same as previous brass products.
Hairlined surface of stainless steel gives calm impression to those who see these products.
The making process is same as that of brass products. After etching process is completed black paint is ran into the concave portion. Then clear coating process is done.
The outline of the fish scale pattern seems more clear than that of brass fish scale Tank Dash Cover.
[ Fish Scale Floorboard Inserts ]
Another stainless steel products are Floorboard Inserts. The picture on the inserts is same as that of brass fish scale Floorboard Inserts.
Sometimes I am asked about the fish etched on the surface of the inserts.
The diagnostic tail part tells you what kind of fish it is.
