If you're looking for help fixing your Suzuki Motorcycle, look no further! Our comprehensive Suzuki Motorcycle Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.

Engage the Clutch
It’s usually a no-brainer for experienced riders, but for newbies, remembering to engage the clutch can mean the difference between a relaxing ride and a frustrating trip to the shop. Many bikes must have the clutch in before they will start—even when you’re in neutral.
There’s also the possibility that your bike’s clutch switch has been damaged, and you can try “pumping” the clutch a few times to see if that helps reset it. You can get around the clutch switch, but long term, you’ll need another solution (and probably a clutch replacement).

Confirm There’s Gas in the Tank
A basic pre-trip check is seeing whether you have gas in the tank, but it’s something riders tend to overlook. Especially if your gas gauge reports a full tank, you might not think to check. Keep in mind that gauges can malfunction, so consider jostling your bike and listening for the slosh of gas in the tank before jumping to other potential problems.
If you can confirm there’s gasoline in your bike, see if the fuel pump is operational (if the motorcycle has one), and if there’s a carburetor, see if there’s gas making its way there, too.

Determine if the Petcock is Clogged
One potential issue that might be keeping your motorcycle from starting up is a clogged petcock. The petcock is a fuel control valve. It controls the gas flow between off, on, and reserve settings. Clogged petcocks are a common issue that riders often bring up in forums.
A minuscule screen helps keep gunk out of the petcock, but corrosion and bits of stray material can cause flow issues. Rattling the petcock a bit can help dislodge any blockages, but replacement or a deep cleaning might be necessary to get your bike running again.

Clear the Muffler
Whether it’s your kids or grandkids, the neighbors, or residents of the rodent variety, someone (or something) could have blocked your muffler. This is especially common if the bike has been in storage for a while, or if it’s been outdoors.
Rodents looking for an accessible home might move into your muffler, but it’s also possible there’s just a ton of debris in there if the bike has sat for a while. Clear it out (carefully) and see if that helps get the bike started.

Check for Blown Fuses
Just like a car or truck, motorcycles have fuses, and they can blow the same as in any other vehicle. Keeping a fuse kit on hand is helpful so you can replace any blown fuses with one that has the same amperage.
If fuses continue to blow after you replace them, you likely have a more serious electrical issue somewhere in the bike’s wiring.

Look for Loose Wires
Another seeming no-brainer is checking electrical connectors to see that everything is plugged in. Electrical issues often escape riders because they aren’t always visible, but manually checking the connectors can help you spot a problem that wouldn’t otherwise reveal itself.
If you suspect something other than the battery is the culprit, especially if you’ve just swapped the battery for a new one, it’s also worth looking at your battery connector cables. It’s possible your new battery’s wiring is incorrect, making your non-start a quick fix once you tighten the cables to the terminals.

Set the Choke Properly
For carbureted motorcycles, you might need to set your choke or mixture enricher to match the ambient/engine temperature. Another common oversight, this issue can crop up in extreme weather conditions, or when conditions take a sudden turn you haven’t accounted for.
