Problems with Aftermarket Float Valves
I get lots of emails like this one:
“I purchased four “Napco Carb rebuild Kits” in addition to some parts from you like plenum seals, etc. I probably should have purchased your Master Kit. Anyway, 2 of the Napco float valves would not seat properly resulting in a lot of frustrating problems. With your recommendation, I cleaned and put the original Honda float valves back into the carbs. Problem Solved. Thanks!”Lee Korb – Raleigh, NC

Single Carb Conversions?
Warning: Controversial Material!
Pictured are a few of the single carb conversions I’ve evaluated (Ford, Solex and Weber carbs shown left-to-right)
I get a few inquiries about single carb conversions. This Tech Tip is my comprehensive answer.

Aftermarket Fuel Filter Mounting Issues
More on the topic of aftermarket fuel filters here

I’ve personally had very few problems using aftermarket fuel filters designed specifically for the GL1000 such as the commonly available EMGO model. However, there have been some reported failures with such aftermarket filters. Fuel leaking from a fuel filter is more than a nuisance…it’s a very serious fire hazard.
Here’s a tip to prevent problems with these filters. The probable cause of leaking aftermarket filters is over-tightening of the 2-part bracket that secures the filter to the front of the fuel tank. If the aftermarket fuel filter has a diameter just slightly larger than the OEM spec, tightening of the retainer screw can put to much stress on the plastic filter housing which may cause it to fail eventually.
Fuel Sender Issues

“OK! Now that you’ve overhauled your carburetors using your Randakk’s® Master Carb Overhaul Kit and installed them on your Gold Wing, you find out that your Wing now performs better than it ever did since you owned it. You check the lights, turn signals, horn, tachometer, temperature gauge, brakes, and turn signals. Everything looks and sounds great!! Then you notice that your fuel gauge shows EMPTY, although you have a full tank.
GL1100 Bogs Down at Full Throttle

If your GL1100 Gold Wing bogs down at full throttle, there are two possible causes.
1. If your air cutoff valves were never replaced since the bike was new, the air cutoff valve diaphragms might be compromised. This can cause a number of carb maladies including “bogging” at full throttle.

Note from Randakk: This information and much more is covered in Howard’s Honda GL1100 Gold Wing Carburetor Repair Guide.
Before you finish reassembly of your carburetors during a rebuild, you need to check the operation of the accelerator pump.
