Randakks Master Carb Kit 100-1223 Cover

World’s Best DOHC Kit!

Randakks Master Carb Kit 100-1223 Cover

 

The architecture of these carbs is very similar to the GL1100, CBX, and CX-500 carbs that we have been supporting with our proprietary Master Kits for quite some time. After fielding numerous requests, Randakk’s has decided to extend coverage to these models.

 

This kit is proprietary to Randakks…you won’t find this available anywhere else at any price.

More on Fuel And Fuel Additives – Fear the Corn?

Warning: Controversial Material!

Corn Ethanol Fuel

I grew up in a farm family in the South, so I’m very fond of corn. Of course I like grits, but my favorite form of corn is high quality bourbon! I have personally benefited from crop subsidies and understand the benefit of the emerging ethanol (made from corn) fuel market to corn farmers. I am sympathetic to their issues.

Not so “Green,” No-Drop Idle Mixture Adjustment Method

I find the factory recommended idle mixture screw setting specs to be very close to ideal. They are listed here for the Honda GL1000.

I do usually richen them up an extra 1/8 to 1/4 turn (out) to compensate for the leaner modern “gasoline” which is diluted with ethanol in most US markets.

But sometimes, you just need an excuse to do some high performance tuning on your bike! 🙂

Viton in Vintage Motorcycle Carburetor Components?

All of the ordinary round orings and many other components in Randakk’s Master Carb Overhaul Kits® are made of genuine Viton®. In fact, every oring we’ve ever shipped has been made of Viton®!

There are actually many “grades” of fluorinated synthetic rubber like Viton®. Randakk’s uses the same spec material that Mercedes and Toyota use in fuel system components that are subjected to the oxygenated “gasoline” marketed in North America.

Plus – through proprietary molds and other tooling assets, we make many other Viton® components ourselves via our own exclusive manufacturing arrangements. The proprietary components made in Randakk’s molds are not available elsewhere.

For diaphragm items such as accelerator pumps and air cut-off valves, we have direct and exclusive sourcing arrangements with superior production partners that by-pass normal trade distribution channels. This allows Randakk’s to impose unique-to-Randakk’s product specifications. 

Why is this important? Read on.
