Question about 1984 Honda VF 1100 C
There is no spark to the plugs
Posted by Anonymous on
Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should 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.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Tilt sensor needs a reset.
11. Security alarm failing to disarm needs reset

SOURCE: hoda vf 750 wont start
hello and welcome
with that long of a storage period it is a safe bet that the jets in the carbs have plugged over. this can happen with little as a month or two without proper winterization or fuel conditioning prior to storage. so the carbs will need to be removed and cleaned properly. this is quite the task on the older v4 hondas. and i would reccomend a manual before doing so. after being removed a good can or two of aresol carb cleaner and a small gauge wire to break up builup can clean these carbs out. this is a very very common problem. and im sure you will find this to be the source for your no start. thank you.

Chances are, YES.
Simple chraging system test:
Turn HIGH BEAM light ON
Run 10 minutes or until warmed up good
Rev the RPMs to at least 3,000
Remove the positive battery cable
If the motorcycle dies, then there IS a charging sytem failure.
If the motorcycle continues to run, have the battery checked at a local parts store. If they do not know the Cold Cranking amps tell them 235.
If it is a charging system failure, send another question and I can walk you through diagnoses and repair.

Replace the spark plug caps and try again. On Honda's the cap is often part of the wire (a dealer part) NGK makes some inexpensive plug caps about $5 each. They should OHM out to 5000 anything above or below and you need to replace them. This should fix the problem.
