GL1000 Carb Synchronization Procedure

You might consider this item ..synchronization is shown: Randakk’s GL1000 Carb Rebuild Video

Proper carb synchronization is the key to a sweet running bike. When carb sync is out of whack, you can have poor idle, poor off-idle response, “hanging” throttle and lazy return to idle. You can even suffer from fouled plugs if one or more throttle butterflies are opening early, thereby partially activating the carb’s progression circuitry. Very small adjustments will have a major impact in idle smoothness!

Everything Affects Everything!

I was inspired to create this Tech Tip after reading an old post by Jim Myers on the Classic Wing Club mail list. The general context of the thread surrounded the issue of setting idle mixture screws.

My view – a proper carb rebuild on a vintage ‘Wing, properly MAINTAINED should be a once-and-done proposition that gives years of reliable and trouble-free service. That’s always been my personal experience!

Otherwise, if you use inferior parts or take shortcuts – you can take advice from Alec Baldwin

Common Honda GL1000 Carburetor Rebuilding Mistakes

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-laws and neighbors. Avoid these mistakes if you tackle a rebuild yourself.

Honda GL1000 / GL1100 / GL1200 Head Gasket Details

Head gaskets on early ‘Wings are ultra reliable. The vast majority of these bikes are still running flawlessly on the original, factory-installed head gaskets which are now 40+ years old. Rare failures are usually caused by inattention and poor maintenance to the cooling system. But, a simple case of overheating can ruin your head gaskets. Warped heads are also a possibly outcome of overheating!

Shade Tree Diagnostic Tests!

I was very fortunate to grow up in a neighborhood and farm family full of excellent shade-tree mechanics. Mostly they were short on cash and long on resourcefulness.

I learned quite a lot by pestering these very talented home-gown mechanics.

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.

Kick Starting a ’75-’77 Honda GL1000

Starters are very reliable on GL1000s, but it’s nice to have a back-up. The back-up kick start lever is found only on ’75-’77 models. Honda deemed this extravagant redundancy was unnecessary and dropped the feature on later models.  I’ve actually needed the kick starter on several occasions to make it home when some aspect of the very reliable electric starting system failed. I also use my kick starter for another reason: it’s a good test of your bike’s overall state of tune. If it will start with the kick start lever, then you have a well tuned bike! There are many maintenance operations (like setting timing) where the kick starter provides some nice convenience.

Motorcycle Fuel Mileage Issues

Warning: Controversial Material!

I get lots of inquiries about fuel mileage these days. It’s no surprise given highly volatile fuel prices! Here’s what I know about the subject.
