Only the highest quality items are included. This kit has been thoroughly tested and represents the best value available in the market.

Here’s a partial list of problems encountered by amateurs when rebuilding GL1000 carbs. Often, I’m called upon to resolve botched rebuilds by incompetent mechanics, current or previous owners, brothers-in-law, and neighbors. Avoid these mistakes if you tackle a rebuild yourself.

Allan Zahrt with his Million Mile GL1000!

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’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!!!!”

Note: The procedure for setting the float levels on GL1100 carbs is essentially the same as the one for GL1000 carbs described below. The only difference is that the float level spec for the GL1100 is 15.5 mm instead of 21.0 mm.
