Okay, when trying to start the starting relay clicks. The battery voltage is 13.4. The triangle is air, fuel, spark. What should I do?

Carburetors just rebuilt and ultrasonic cleaned. Sat for 2 months while carburetors were cleaned and now no start.

 

Standard troubleshooting steps:

1. measure battery voltage with everything OFF, volts = ???

2. measure battery voltage with key ON, start/stop=RUN, volts = ???

3. measure battery voltage while pushing start-button, volts = ???

4a. jumpstart bike with known-good auto battery. That's battery that can start car just fine. Leave car OFF, we're just borrowing its battery power. Wiggle jumper-cable clamps on both ends to get good bite and conductivity. Measure same #1-3 with auto battery connected. Does it start bike???

4b. If NOT, then you've got wiring problem between battery & starter/bike and power isn't being transferred across efficiently.

 

Used a $7 starter relay and the bike turned over. Went and got gas for the line and tried to start again and the clicking began all over again.

 

Troubleshooting is useless without numbers.

This is 5-minute fix with multimeter. I’ve fixed for 100s of people. Most of them in remote parking lots in middle of night by phone. Many in pouring rain! 5-minutes is all it takes to measure.

Honda hired great engineers to design and build bike along with writing manual. Only way they can help people they can’t talk to when things go wrong decades later is by comparing numbers. Somewhere, some place, you will measure a number that’s different than what manual says it should be. That’s where we focus for more in-depth measuring. Then only need to replace ONE part that is actual cause of this problem. Most of time, it’s just corroded wiring or connectors.

Without numbers, you might as well keep on guessing and replace following (only brand-new factory OEM parts from authorised Honda dealer):

- battery cables
- starter
- start button
- ignition switch
- kill switch
- wiring harness
- spark plugs
- ignition coils
- ignitor
- battery

Also measure for parasitic drain when OFF.

 

Okay, I will try this. WOW
by the way the starter relay replacement by Niche gave it a start however the gas was not connected and when connected the gas there was start just clicking. Will try the multimeter and post photos.

 

Yea, ​​​​​@dannoxyz does come off kind of strong sometimes, but he does have a really high success rate for those that are willing to follow his suggestions.

 

So the starting realy clicks - what you didn't say is whether the starter turns...

the air/fuel/spark equation assumes the engine is turning over - if it's not, none of that matters.

jump from a car battery (car engine off!) to eliminate the most obvious cause of the problem - a bad battery.
