Yamaha Grizzly 700 Problems

Yamaha Grizzly 700 Problems

1. It is unstable around corners and on hills.

Owners of Grizzly quads often praise the quad’s stability. It can be unstable when it is turning or climbing hills. 

It is lightweight and can handle any obstacle well. The instability is also caused by its small size and high seating.

2. The engine is loud and overheats.

Yamaha Grizzly 700 has only one cylinder. This is a problem that many people consider a disadvantage. 

It produces more noise than quads with two-cylinder engines but has less power. This could also cause overheating issues. This can be solved by adding a radiator. To reduce noise, you could add a second muffler on the rear rack.

3. Filter can be clogged by dirt and dust.

Owners have reported that dirt and sand can get in the filter. This can cause damage to internal engine parts such as valves and pistons.

It could also lead to poor engine performance and excessive oil consumption. Apply filter grease to the outside edges and secure the filter in place. 

This will prevent any debris from entering the filter. You should inspect the airbox frequently if you ride in dusty conditions.

4. On startup, the quad smokes.

This problem is part of the 2016 Yamaha Grizzly 700 issues and is caused by valve problems. 

It is best to take it to Yamaha dealers for proper diagnosis and resolution. You can also check the engine valve clearance to determine if it requires adjustment.

5. Sometimes it won’t even start.

All Yamaha Grizzly 700-year models have starter problems. The spring on the compression may cause this problem. This spring must be reinstalled. If the valves are too tight, they may need to be adjusted.

Other times, the problem could be electrical. This is especially true for Yamaha Grizzly 700s equipped with auto EPS. Here are some tools that you might need to fix the Grizzly’s problems.

  • Sockets 10- and 12-mm
  • 4 mm Allen
  • Phillips screwdriver
  • Volt/Ohm Meter (capable to test diodes).
  • Check out the lead kit

Depending on what tests you’ll be doing on your Yamaha Grizzly 4wheeler you might not need all the tools. For wiring diagrams, refer to your owner’s guide.

6. The gas tank rollover valve has a defect.

You may hear a hissing sound after you remove the gas cap from your Yamaha Grizzly 700. 

Your rollover valve may be defective or not venting properly. This was a problem that Yamaha fixed with an upgraded rollover valve. To have it replaced, contact your dealer.

7. The engine then stops working and dies.

Even 4WD Yamahas with less than 50k miles can experience this issue. This is easily spotted as the quad will stop working when it is idle, and then backfire occasionally. 

The Grizzly may also experience extreme pressure in its gas tank, and power problems when loaded. 

This could be caused by contaminated fuel, worn-out sparkplugs, fuel-starved motor, and a bad fuel pump.

8. When it is in 4WD or 2WD, it makes a loud clanking sound.

This happens most often after you have pushed the throttle on your Yamaha quads. Initial speculation was that the problem could be due to a broken axle. Modded Yamaha ATVs may have issues with their bearings or axles. 

Owners would later trace the problem back to a defective transmission, or a differential. You will need to first disconnect the driveshaft in order to pinpoint the cause.

9. New brake pads can make rear brakes spongy.

The braking system on Yamaha Grizzlys is very reliable. Spongy rear brakes could be caused by not giving the brakes a thorough bleed before installing new pads. 

If you have this problem, use a turkey baster or a power-bleeder. When bleeding, make sure you use DOT 4.

10. Poor acceleration is a problem for the quad.

Yamaha Grizzly 700′s poor air filter design causes the engine to feel deprived and perform poorly when acceleration is attempted. The problem could be caused by a clogged filter that does not allow enough air to the engine’s intake. 

A clogged air filter can also cause bad gas to build up, which can lead to the engine running erratically.

11. It is hard to start cold-weather activities.

Yamaha Grizzly owners of older models 2016 and later complain about the difficulty in turning the engine and the inability to cold-start despite having an electrical starting system that works properly. 

The problem is caused due to a defective decompression spring that was damaged during manufacturing. 

Yamaha issued a recall in July 2016 for affected Grizzly units and Kodiak units. Owners were advised to contact their Yamaha dealers to have the defective part replaced by a better-quality decompression spring.

12. It has problems with steering control.

Yamaha Grizzly power steering issues for 2008, 2009, and 2010 models led to a recall of 20,000 700- and 550-class Grizzlys, as well as hundreds of lawsuits in rollover accidents. 

A defect in the steering column support assembly caused the steering problem. This could have led to riders losing control and possibly sustaining injuries. This was an isolated issue that only affected those model years.

Testing for Problems

How to Test for Problems – What You Need to Watch Out For

It is important to identify common problems with the Grizzly and also know their solutions. Here are some ways you can prevent these issues:

  • Verify that your battery registers at least 12.5V. This is a great first step especially when you are trying to troubleshoot 2008 Yamaha Grizzly 700 problems during startup. 
  • Any value below this level is an indication of an unhealthy battery and would require a replacement. The Battery Tender (view Amazon) is ideal for prolonging your battery’s lifespan. It monitors and charges the battery as needed.
  • Verify that the starter solenoid is firing up. To test the starter solenoid’s response to contact with its terminals, you will need a test kit. 
  • If it responds, the problem can be ruled out as a starter motor issue. 
  • If it does not, the starter motor is likely to be defective. To determine the source of the problem, you may have to check other parts of the quad: the relay assembly and brake light relay, diode relay, diode relay, diode relay, run connector, engine start switch, and rear switch.
  • You should inspect the oil for signs of water. Water contamination can lead to bearing wear and engine oil denatured. These two factors can cause severe damage to your engine’s cooling system.
  • Check the oil level. It is not common for the stator to heat up if it has an incorrect or low level of oil. This can be mistaken with a bad battery or other causes. 
  • If you have an overheating issue with your Grizzly 700 engine, make sure to check the oil level and condition of your stator before replacing your stock battery. Replace the stator and attach a new cover to it if it is the cause.
  • Look for cracks or dents in the tie rods and bearings. These are the main culprits behind popping and clanking sounds on the Grizzly. These parts can be grubbed more often to slow down the process of deterioration.
  • Check your radiator for bent fins. This reduces the tube’s contact surface with the air and decreases the exchange efficiency. This can cause engine overheating and make your quad’s cooling system less efficient. If you ride in temperatures over 110 degrees F, this is a must. It is also important to keep your radiator clean after any mud runs.
  • Inspect the air filter. Older Grizzly models need to have their air filters inspected regularly to ensure good engine performance and responsive throttle control. Air filter clogging is unlikely with 2015 models and newer models that have a high-flow system and an optimized intake joint. 
  • The air intake is better at keeping water, mud, and other particles out of the internal system.
  • Test the power steering for resistance. Turn your Yamaha Grizzly completely left and right. Any resistance could indicate a defect in the torque sensor, speed sensor, spline columns, or EPS controller unit.
  • Check bolts and nuts regularly. This is especially important if your ATV has an upgraded model. 
  • These bolts should be touched, tightened, and torqued regularly: lug nuts; pivot bolt; axle nut; wheel hubs; skid plate bolts, and sprocket screws.
  • Use figure 8s to ride and listen out for the popping sound from the CV shafts. This could indicate that the one-way bearing was installed incorrectly or backward. One-way links the CVT to engine crank deceleration. It should not make any noise. It could be a problem with the bearing or the primary shaft support bearing within the shaft support cage that is worn or dry.
  • Check the brakes. Do this after you have installed new brakes. Check that the rear and front brakes are not spongy. To resolve any problems, perform a complete bleed-in.
