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.

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! 🙂

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

Randakk now offers GL1000 and GL1100 Float Setting gauges. Details here
I show how to set floats in the video: Randakk’s GL1000 Carb Rebuild Video
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.
Note: an objective analysis of available Honda GL1000 carb kits was recently completed by Ron Carmichael.

Honda made a number of jetting tweaks in ’76 (K1 and LTD) and again in ’77 (K2) for US-bound GL1000s to cope with tightening emissions regulations. Other markets were affected as well. Honda necessarily made the bikes progressively leaner through these model years. Social responsibility is a good thing for large corporations, but these were not great moves from the rider’s point of view. Riding a bike with overly lean carburetion may be “green,” but it certainly can be frustrating.
