Obviously there is a wrong connection, or a hot wire grounding were it should not, somewhere on the bike. Remove the seat and gas tank to gain access to the wiring harness. Get a volt Ohmmeter as you may need to check continuity at some point. Start at the battery, then fuses and the wires connecting to the fuses. Inspect for burned wires, abraded wires, loose and/or dirty connections, bad connectors and loose wires. This means the mass of wires inside the headlight must also be inspected. Check the handlebar kill switch and the side stand kill switch as well. Go all the way to the ignition system. Check the key switch. Put it on "run" and check for power through the switch as you jiggle the wires. Find the problem and you should be able to fix it. A wiring diagram would help.

1975 Honda CB360T will not turn over


Hi, A_leri before testing any electrical component in the Starting 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 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. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Engine Run Switch is "FAULTY" or corroded.
4. 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.
5. Bank angle sensor needs a reset or is faulty.
6. FOB battery low or dead.
7. Faulty ignition switch.
8. Faulty starter button.
9. Faulty kickstand, clutch, neutral safety switch.
10. Security alarm needs a reset.
11. Starter relay, solenoid, starter motor or circuit wiring faulty.
12. Starter armature or field coils have failed.
13. Main fuse or circuit breaker may be blown or faulty.
14. Faulty ignition relay.
15. The electric starter is working but starter clutch has failed.
16. Check for engine trouble codes.

1974 Honda CB 360 one of my carbs is not getting fuel


Hi, Steveholsapp you need to locate the fuel flow origin first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing.
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn.
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working.
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.

Rear breaks


Do you stop when you put on the brake? Any funny noises? Does the foot lever go down and back up properly? Any further determination would mean a dissembly and visual inspection.

How to check the points on a cb360


Are you getting spark from both plugs when the engine is kicked over? If so, the points are working. How well they are working and the accuracy of the timing is another matter.

What would be a good plan for repairing an old CB360?


  • First thing is to get a factory repair manual. Next is to wash the bike with special attention to the gear box and cylinder. Mud falling from a cylinder and into the crank is not a good thing.
  • Assess the engine as a whole. Does it look like everything is there? Any missing side plates? Make a list of known parts needed; engine parts and body , frame, electrical, wheels, cables etc.. Locate a source or sources for used parts. Go to Google and input “ motorcycle salvage honda “. Start there.
  • Only work on the engine. Replacing a headlight is pretty useless if the engine is trash.
  • Start with the gearbox. Does the kick start turn the crank? Let’s say it does. Put the bike on the center stand and turn the rear wheel. Pull the clutch in and shift into 1st, neutral, 2nd and up to 5th then back down to 1st. If the shift lever locks up, or if it is extremely stiff in changing any of the gears, then you know that shift forks are needed. Chances are that nothing else is going to be wrong with the gearbox other than new crank bearings going in while the gearbox is opened up for shift fork replacement..
  • Now check out the top end. Pistons going up and down? Doesn’t matter. You will want fresh cylinder bores and new pistons and rings for the rebuild.
  • Look at the electrics. Is the wiring harness burned anywhere?
  • You may want to short cycle the rebuild process if the shifter is okay and the crankshaft turns over. Forget the pistons etc., just get the motor to run. The satisfaction will be immense and you can tear down the top end later.
