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!

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.

Does your early GL1000 sound like a rattling bucket of bolts when idling? If so, you might have a serious engine problem but most likely you do not. Read on…

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.

My recommendation for Honda GL1000 timing belts is simple: It you can’t verify their age – change them! Thereafter, my recommendation is to change them every 5 years or 25,000 miles…whichever comes sooner. Obviously, they should be inspected from time to time for any evidence of damage, oil contamination or deterioration which would warrant immediate replacement.
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! 🙂
