Flooding Issues on Vintage Hondas

Flooding is a common problem in vintage Hondas – especially on bikes that don’t get run much.  Flooding can be just a minor aggravation …like hard starting or poor fuel mileage. But, it can also lead to catastrophic problems such as severe engine damage or even a fire!  Flooding issues should not be ignored!

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.

January 2018’s Featured Products

Happy New Year, Goldwing lovers!

Looking back on 2017,  you probably put a healthy number of miles on your Honda. You know this is right up the Randakk’s alley when we say that you may be due for a carb cleaning/rebuild.

  • Is your motorcycle hard to start?
  • Is it running a bit off-kilter?
  • When you dial the throttle, are you getting the desired performance?
  • Do you ride with the choke on? (this means you have a clogged pilot jet)
  • Sluggish acceleration?
  • Bad fuel economy?

These are all signs that your bike is in need of some carburetor love. In most scenarios, there’s only really one way to see if your carbs are due for a complete rebuild: pull them off the bike and take a look inside. And since you have them off and dissembled, you might as well do your future self a favor and rebuild them now.

January’s Featured Products are dedicated to those precious carburetors, everything from the all-inclusive Randakk’s Carb Rebuild Kits to the e-clips.

“Insensitive” Idle Mixture Fuel Screws?

I often field this common complaint: 

“I’ve noticed that turning the idle mixture screws nets different results on each of the individual carbs on my Honda GL1000:

  • #1 will kill the motor if turned all the way in
  • #3 has NO EFFECT on engine speed regardless of where it is set
  • #2 has what might be considered a “normal” effect
  • #4 has only a very slight effect if any at all

What does this mean????? I’m a bit confused?  Help please!!!!”

“Reversed” Front Brake Calipers on Vintage Hondas?

On some bikes (including the Honda GL1000), the front calipers can actually be installed on the wrong side!  Front brake calipers on all bikes must be installed with the bleed screw “up.”

This simple requirement can get corrupted when brake parts are carelessly “mixed-and matched” or installed without care.  Whatever the explanation, this error leads to two serious issues:

  • Brake hoses will be too short and “kinked” at an odd angle creating a serious safety hazard!
  • Air bleed nipples with be rendered worthless, since they are no longer at the top of the caliper where air bubbles rise. The brake system can never be fully “bled” of trapped air.

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.
