Allan Zahrt with his Million Mile GL1000!

In the early seventies Honda launched without fanfare an ambitious project. Internally, Honda had a bold plan: to build the world’s best motorcycle. Not just the best Japanese motorcycle  – the best motorcycle available anywhere in the world. Period! The eventual result of this project was revealed to the world at the Cologne, Germany International Motorcycle Show (INTERMOT) in October, 1974 as the GL1000.

“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.
