My Motorcycle Won't Start, What Do I Need To Do
21 - 34 of 34 Posts
Adding on folks,
Can't get my CB650 to get going
I've replaced the battery
Drained the fuel, replaced with new premium gas
Carbs have been rebuilt
Spark plugs look good
Had a friend mention the "points or stator" but that is beyond my scope of knowledge
Any advice???
Thanks

Well here's the best way to narrow down your issue:
Take carb cleaner or starting fluid and spray a bit into the into the carb from the air filter side. Then try to start the engine. If it fires or tries to fire then your issue is with fuel. If it just cranks with no sign of life, your issue is spark.
Starting fluid is much stronger than carb cleaner so be careful with it.
Spark problems are often needing a new coil, plug, or cdi.
Fuel problems can be petcock, carburetor, fuel pump, or maybe even vacuum (in the case of vacuum operated fuel pumps).

New forum user here, I've been having trouble starting my 2002 suzuki bandit gsf600s. When I try to turn it over I only get a pitiful crank or two and the lights cut off. The battery reads 12.9V (its only about two years old). The lights come on just fine and it will run fine if I push or jump start it, or start it while its still warm.
This started happening when the weather got hot here past the 70s. Another possibly unrelated issue its been having is idling high (around 3k) and sometimes dying when I give it gas at a light. The carbs are probably due for a clean.

It would sure be nice and appreciated, if you would introduce yourself to the community in the New Member Introduction forum. Folks tend to open up more if they believe they know someone just a little bit. 👍

Hi guys,
Also trouble starting my motorcycle.
I'm riding a Yamaha Fazer 1000cc from 2003. Up until now it always started but often after 2-3 tries. (Last big maintenance: 1.5 months ago)
Now yesterday my motorcycle died on me in the middle of the street. I wasn't far yet so I could push back the bike but I'd prefer this not happening when I'm 100 km out.
I started my motorcycle normally. It was the first night freezing over here, so I put the choke full on and started the engine. First go, engine started turning, let it run for about a minute while sorting my gear and then left. Three streets further I was standing in front of the traffic lights and the engine started revving up to about 3500 rpm. A choke is a bit from before my time so I didn't think about reducing the choke to bring down the rpm. Instead I shut down the bike (these traffic lights take a long long long time to turn green). Once they turned green my bike wouldn't start anymore. First times it cranked and coughed once or twice but then nothing. Of course I was in the middle of the street stressing, so I kept trying until the battery eventually died.
In the afternoon I went to buy a trickle charger to charge my battery but I couldn't get my bike started anymore. Everytime the same thing: crank, 1 cough, nothing.
Now I don't know what to do. Should I wait a bit for warmer weahter to try and start it? Should I keep trying?
I'm technical but I don't know anything about motorcycles so any guidance would be appreciated!
And a side question: what to do in the situation I described. Keep trying to start it until the battery is empty? Alternatives?
Have a nice Sunday!

Most common problem is the battery. But bikes often sit for a while, which creates other problems. I am only going to talk about the battery. In this case Herb, my 1941 Ford tractor.
The other day Herb failed to fire. He cranked over okay but a bit slow. He probably should have fired. BUT. I remember back many years. A tired starter motor, and a tired battery. What happens. The starter motor uses all the available power from the battery. Nothing left for the ignition.
Herb usually fires right away. He has an electronic ignition. Unless that failed, or a wyre came of, the main suspect is the battery. He cranked a bit slow the last time I used him a few weeks ago. I disconnected the solar charging unit and checked the battery. About 13 volts. Let sit for a day. 12.27 volts. That is half flat. Not enough. We need 12.75 or thereabouts for a full charge after sitting a day or two. Pull the battery out and connect to load tester. BAD.
Off to the store. She checked with her load tester. BAD. New battery. Herb fired first crank. Peace and harmony all about.
The battery in Yami sits at 12.85 volts, after two weeks over Christmas. Herb battery was 6 years old.
I did check for fuel at the carb which is gravity fed. UK

I wold start from checking wires and connectors in aria i work changing oil. Previously turned wire at sensor or connector can be easily snapped by touching one.
