Hi, Allen the following is a systematic procedure for diagnosing fuel pump issues designed to keep "DRACHMA" to a minimum. If you need parts check with Amazon and eBay first to keep costs down.
1. If your pump does not turn on check the pump fuse and relay and all wiring including connectors for corroded, broken, or loose pins/sockets.
1. Normal fuel pump pressure is 3-5 PSI.
2. Check any rubber or plastic tubing for age-related pinholes by removing and plugging the ends that connect to the fuel valve and then turn on the ignition switch and watch for fuel streams exiting the pinholes, if any exist, replace tubing as necessary.
3. Check for a clogged a primary fuel filter that comes off the bottom of the pump to screen out big rocks and clean as necessary.
4. Check for a clogged secondary fuel filter that's outside if applicable by removing it from the system and replace it with a short splicing tube turn on the ignition switch and recheck fuel pressure if pressure increases to normal pressure you need a new secondary filter.
5. If all the above check out OK and the pump is not functioning properly then you need a new fuel pump.

SOURCE: How can I get old fuel out of the reserve tank on

Hi,
Just disconnect the main fuel hose from the carb rail. Ensure that you have switched the fuel **** to reserve and this will allow the reserve tank to empty. Not all the fuel is going to come out unless you blow air into the fuel tank filler, this will then get a large percentage of the fuel out. Hope this helps, let me know how you get on.

SOURCE: 1996 honda magna vf750 fuel pump, need rebuild kit

Your model 95 or 96 VF750 Magna does not have a fuel pump. I believe the part you are talking about is the vacuum fuel petcock assembly. The part is only sold from Honda as an assembly.The part number is # 16970-MZ5-003 and runs about $120.

I have a 82 Honda magna vf740c I changed all fuel line orings put it back together and now I can't get it to start. Its got fuel to carbs. Good spark and air flow but won't start any segestions


Hi, Travis and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).

Severely discharged or a damaged battery must have 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 batteries fail in this scenario more so than lead acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.

5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.

10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.

Hi, Anonymous before testing any electrical component in the Starter Circuit 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 because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, especially "AGM" batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

How do i fit a fan overide switch to a honda vf750


Is there a problem with the thermo switch? this would probably be a lot simpler to just replace it if it is faulty and on all the time.
As for an override switch just go the fan and find the wires and snip one of them and redirect the wires to a toggle switch.

I need to clean out my carbs for my 82 honda 750 how easy is it? is it worth the time? How much usually does it cost to get done professionally? I also have a cracked crank case cover, and so it leaks oil,...


here is a clue you need to follow, i have been working on bikes for years, the v4 engines are the hardest to remove/install/and clean take it to a dealer and let the deal with the headache yo will be glad you did, the crankcase cover is easy to replace, just buy the gasket before hand and once you have it loose remove it very slowly, to get the carbs done by a shop you are looking at about 125.00
