We deign and create parts for Harley-Davidson motorcycles.
I added carbon fiber tank dash console covers to the list of the products.
They fit Harley-Davidson FXR models equipped with fuel gauge on the fuel tank.
They are made of 0.6mm thickness dry carbon fiber reinforced plastic board and contain adhesive tapes.
3 sets of “aluminum and brass speaker covers” for FXRD (FXRT) fairing are restocked.
A6061 Speaker Covers with Brass Plates Ver2 for FXRD fairing
This time, I changed material of the base parts from A5052 to A6061 with the intention of improving the overall look of the products.
Each speaker cover is consists of a6061 aluminum base part and etched brass plate.
Mounting hardware (brass slotted screws and wellnuts) are included.
*The dimensions of the base parts and Harley-Davidson original plastic covers are identical.
*When installing, minor modification (enlarging the holes for wellnuts) is necessary.
Second version of speaker covers for Harley-Davidson FXRD fairing.
Etched plates which are made of brass have more simple appearance than predecessor.
Grill part is honeycomb style mesh and other part of the plate has no specific design. It is just painted black.
Base plates are made of A5052 aluminum alloy.
Kit contains 4 slotted bolts and 4 wellnuts.
To mount these covers on fairing, a little work is necessary. Please ream the mounting holes existing on the fairing so that the wellnuts can be inserted in them.

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.
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.
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.
