I get a few inquiries about single carb conversions. This Tech Tip is my comprehensive answer.

Are you plagued with a bike that runs great from about 2000 RPMs and up, but refuses to idle reliably below that speed? Does it sometimes idle OK, but often “hang-up” at a higher speed and take forever to return to idle? Do you have to put a small load on the engine (by letting out the clutch a bit when stopped and in gear) to get the engine to return to idle speed? Does the idle speed seem overly sensitive to changes in ambient and operating temperature? If so, read on.

Throttle cable replacement on GL1000s is a straightforward operation, but there is a trick I will share which makes it much easier to accomplish.

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.

The air cutoff valve is a simple but vital component of the carburetor system on GL1000s. Its function is to eliminate backfiring on hard deceleration (throttle fully closed). Hard deceleration creates a high vacuum signal in the intake tract which activates the valve. When activated, it restricts the flow of air to the external idle circuit air jets thereby richening the mixture. This slightly richer mixture is calibrated to eliminate backfiring in this operational mode.
Here are some recommended maintenance items you can address while you are awaiting the return of your rebuilt carbs. Most of this is written from the GL1000 perspective, but generally applies to other models as well.
Imperative – all tune-up issues must be in order before you synchronize your freshly serviced carbs. Especially: plugs, plug wires, points and timing! Click here for my “Tech Tips” section for helpful information on setting points and ignition timing properly.

It is very important that the intake runners on your GL1000 provide a leak-free connection between the individual carbs and the cylinder head. During carb rebuilds, I remove the intakes for individual inspection and leak testing. This is also necessary to gain access for inspecting the throttle butterfly plates and retaining screws as well as the idle nozzles.
However, you probably shouldn’t disturb the bonded rubber connection to the carbs any more than necessary. Remember these parts are 25+ years old and the rubber is not as pliable as when new.
