Hi, Chuck before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Battery Test:
The battery needs to be a fully charged and load tested to ensure proper readings, connections need to be clean and tight. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Standing battery Voltage should be 12.5-13.2 DCV.
2. Charging System Voltage Test:
Start motorcycle, measure DC volts across the battery terminals you should have a reading of approximately 13.2-15 DC Volts.
3. Connections and wires:
Inspect the regulator stator plug, and check the battery terminals for connection corrosion. If everything seems to be in order, move on to number 4 below to determine if there's a failed component.
4. Stator Checks/Rotor Check: Each of the following tests isolates the Stator & Rotor. If AC output and resistance test fail and stator test passes then the rotor is at fault (Pull Primary covers and inspect rotor for damage).
5. AC Output Check:
Unplug the regulator plug from the stator start motorcycle and change Voltmeter to AC volts. Probe both stator wires with your meter lead. The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. Reading will vary depending on system, check service manual specification
22 amp system produces about 19-26 VAC per 1,000 rpm
32 amp system produces about 16-20 VAC per 1,000 rpm
45 amp system produces about 19-26 VAC per 1,000 rpm
Stator Resistance Check:
Switch your multimeter to Ohm x 1 scale. Probe each stator wires with meter leads and check resistance on the meter.
Resistance should be in the range of 0.1-0.5 Ohms. Reading will vary depending on the system, check the service manual for specifications.
22 amp system produces about 0.2 to 0.4 ohms
32 amp system produces about 0.1 to 0.2 ohms
45 amp system produces about 0.1 to 0.2 ohms
Stator Ground Check:
Switch your multimeter to Ohm x 1 scale.
Probe each stator wire with your positive lead on the multimeter and the negative to ground.
There should be no continuity to ground on either wire.
If there is continuity your stator is shorted to ground and must be replaced.
5. Regulator Test:
Each of the following tests isolates the regulator only, so if any of these tests fail, the regulator is at fault.
Battery Charge Lead- Wire going from regulator to battery positive.
AC output leads- Wires coming from the Stator to the regulator.
Ground- Wire from Regulator to ground or regulator may be grounded via the physical bolting to chassis.
Regulator Ground Test: Ensure the regulator body is grounded or grounding wire is fastened tightly to a good ground (you should verify this by checking continuity from regulator body to chassis ground).
Fwd/Reverse Bias Test/Diode Test:
This check is testing the Diode function to ensure it is regulating the AC current for the stator into DC Current.
Switch multimeter to Diode Scale.
Place your Multimeter positive lead on each AC output wire.
Place your multimeter negative lead on the battery Charge wire.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the AC output wires and the Positive lead on the Battery Charge Wire. The reading should be Infinite. With your meter on the same setting, place your multimeter positive lead on the regulator ground wire or to the regulator directly, and then place your meter negative lead on the AC output leads.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the regulator ground and the Positive lead on the AC output wires. The reading should be Infinite.
Note: Below is a table to show the readings:
Positive Lead Negative Lead Reading
AC output 1 Battery charge lead Voltage
AC output 2 Battery Charge Lead Voltage
Battery charge lead AC output 1 ?
Battery charge lead AC output 2 ?
Ground AC output 1 Voltage
Ground AC output 2 Voltage
AC output 1 Ground ?
AC output 2 Ground ?

Use small headed maybe even needle nose vise grips if you can get it on tight, then use a pipe wrench or crescent wrench to turn the vise grips. If you have a propane torch heat it first then spray with a rust break free spray ten eat again and try turning. good luck!
Check you petcock for correct operation and make sure its not clogged. If its a vacuume actuated petcock, make sure the hose is attached well and not leaking. If all is well with those 2 things then try seeing if gas will flow when you remove the gas cap. If that fixes the problem, then the vent holes on your gas cap are clogged up.
Ethanol in the fuel will often lower a bikes idle speed. Honda gives you a simple screw to turn to raise or lower the idle speed on your motorcycle. it is part #10 on the following diagram.
The black plastic knob is located on the left side of the engine, when you are sitting on the bike, under the carburetor. Try turning the knob 1/4 to 1/2 turn clockwise. This should open the carburetor just enough to allow the cycle to idle again.
Hi, Les and the usual suspects are:
1. Improperly loaded motorcycle. Non-standard equipment on the front end such as heavy radio receivers extra lighting equipment or luggage tends to cause unstable handling.
2. Incorrect air suspension pressure.
3. Damaged tires or improper front-rear tire combination.
4. Irregular or peaked front tire tread wear.
5. Incorrect tire pressure.
6. The shock absorber is not functioning normally.
7. Loose wheel axle nuts. Torque to recommended specifications.
8. Excessive wheel hub bearing end play.
9. Improperly vehicle alignment.
10. Steering head bearings improperly adjusted.
11. Tire and wheel unbalanced.
12. Rims and tires are out-of-round or eccentric with the hub.
13. Rims and tires are out-of-true sideways.
14. Loose spokes.
15. Shock absorber improperly adjusted.
16. Worn engine stabilizer links.
17. Damaged rear engine isolation mounts.
18. Swing arm pivot shaft improperly tightened or assembled.

See if your ignition system like your plugs, coil and leads are providing spark.. Wet or oily plugs shows that the fuel mixture is not combusted.. Check your current source ( battery) is providing enough current too..
This search will go pretty quickly. The fault will be between the gas tank and the carburetor. Check the gas cap (that it is venting), the pet (that it is open and flowing), Unplug the fuel-line from the carb and check that fuel is flowing freely, and then remove the bowl, from the carb and check the "Needle and Seat", Inspect then and check that they are operating normally. Write back with any questions, good luck.
I have a 81 900 custom honda that had a vacuum valve that would not allow fuel to go to carburetors unless the vacuum of the engine was present. Since I did not want to have to turn over the motor for a long time to get gas to the carbs I found that locating the vent tube connected to the other side of the diaphram and blowing into it pushed the diaphragm open and allowed fuel to flow to carburetors. Maybe this will work for you too. Hope this helps.
