Only the highest quality items are included. This kit has been thoroughly tested and represents the best value available in the market.
Trust us, you’ll need everything in this kit to do a proper overhaul of your carbs.
Recommended Honda GL1000 Timing Belt Change Interval
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.
Not so “Green,” No-Drop Idle Mixture Adjustment Method
I find the factory recommended idle mixture screw setting specs to be very close to ideal. They are listed here for the Honda GL1000.

Idle FUEL Mixture Screw on 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! 🙂

GL1000 Starter Clutch Overhaul Tips
Starter clutch overhaul is an easy, but rather time-consuming task. If you have a starter that won’t engage or disengage reliably, your starter clutch probably needs attention. “Howling” or “screeching” noises from the left, rear side of the engine are other symptoms pointing to starter clutch or starter sprocket issues that require overhaul.

Ballast Resistors Explained + Ballast Testing Procedure
Like most battery/coil setups of this vintage, early GoldWings feature a “wasted spark” ignition design. This clever design was chosen by the engineers to save weight and space. Thus, only 2 coils are required to fire 4 spark plugs. All without a distributor as in most cars of this era.
