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 a 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 on 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.

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!
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.

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.
Vintage Motorcycle Carbs – Lean vs. Rich?
Experienced wrenches sometimes forget that we operate with a set of understandings that becomes so ingrained as to become second nature. I don’t normally rely on gizmos like the K&N Air Fuel Monitor shown on my supercharged GL1000 (above). But since things happen so quickly on that bike, it’s a useful and entertaining tuning aid.
