Overview of the Suzuki Boulevard M90

The Suzuki Boulevard M90 is a big, beefy cruiser that was first introduced in 2009. It's powered by a 1462cc liquid-cooled V-twin engine, and it's built on a sturdy chassis with a low seat height and a wide, comfortable seat. It's a great bike for both experienced riders and beginners alike, and it's packed with features that make M90 a great choice for touring or commuting.

However, no motorcycle is perfect, including Suzuki Boulevard M90. So let's review some of the most common problems that may affect your bike, as well as what you can do to fix or prevent them.

Common problems with the motorcycle

• Model 2009 rectifier issues

The rectifier is a vital component of your Suzuki Boulevard M90's charging system, and if it fails, it can cause different problems. The most common symptom of a failing rectifier is dim headlights or other electrical issues. Your bike may also stall or accelerate by itself.

If you suspect that your rectifier is failing, the best thing to do is take it to a qualified mechanic for a diagnosis. In most cases, the rectifier will need to be replaced.

• The instrument panel on the 2010 model can be difficult to see at night.

Many Suzuki Boulevard M90 owners have complained that the instrument panel is difficult to see at night. This is due to the fact that the background lighting is not very bright.

There are a few different ways how you can fix this problem. One option is to install some aftermarket LED lights in the instrument cluster. Another option is to replace the factory bulbs with brighter ones.

• Hard shifting

Another common complaint among Suzuki Boulevard M90 owners is hard shifting, especially on the 2009 and 2010 models. This issue is probably one of the most frustrating because it can make riding your bike a real challenge.

If you're experiencing hard shifting, the first thing you should do is check the condition of your clutch. If the clutch is worn out, it will need to be replaced. In some cases, the problem may also be with the shifter mechanism itself.

Make sure to adjust your clutch cable according to the Suzuki Boulevard M90 service manual to ensure that it is set at the correct tension. If the problem persists, you may need to have your bike's shifting mechanism adjusted or replaced by a qualified mechanic.

• Overheating problem

Another common issue with the Suzuki Boulevard M90 is overheating. This is usually caused by a build-up of deposits in the cooling system, and it can be a real problem if left unchecked.

Furthermore, the fan on the Suzuki Boulevard M90 is known to turn on only when 105°C is reached. So, you can only imagine how hot the M90 engine gets without the fan turning on earlier.

To prevent your bike from overheating, make sure to flush the cooling system and change the coolant according to the schedule in the service manual. You may also want to install a higher-flow water pump to help improve cooling.

• Low Power

Some owners have also reported low power output from their Suzuki Boulevard M90. In most cases, it is absolutely normal as M90 is a cruiser. It is heavy (weighing nearly 730 lbs) and not made for racing. The low power output is due to the fact that it has a 73-horse power engine.

• "Oil puking" issues

Lastly, some Suzuki Boulevard M90 owners have complained about "oil puking" issues. This is when oil starts to leak from the bike, usually from the valve cover gasket.

If you're experiencing this M90 problem, the best thing to do is take your bike to a qualified mechanic for a diagnosis. In most cases, the M90 valve cover gasket will need to be replaced.

• Low handlebars

While most M90 owners love the low handlebars, some have found them to be a bit too low. This can make M90 difficult to ride for long periods of time, as your arms can get tired quickly.

If you're having this M90 problem, there are a few different options that you can try. One option is to buy handlebar risers, which will raise the handlebars slightly. Another option is to replace the handlebars with a taller set.

The price for the handlebar rising kit is only $20-$60, so it is a low-cost option to try. Replacing the handlebars will be more expensive, but it may be the best option if you're not happy with the risers.
