Yamaha Grizzly 600 Problems

Here are the most frequent issues that owners have had to face in their Grizzly four-wheelers worth observing:

  • Noise Excessive: Perhaps, the most major drawback of an engine that is rally-inspired is the associated noise. To those who have been around for a while, they know this is normal and is not a problem much since the engine’s top-end was based on the XT600, a double-purpose Enduro bike. 
  • The Grizzly’s enormous power and torque can more than makeup for the engine’s sound. The installation of an exhaust cap on the stock exhaust an exhaust silencer cap or a big Gun Exhaust 07-1342, ECO Utility’s Silver Slip-On exhaust (view the item on Amazon) reduces the noise.
  • overheating Because of its massive air-cooled single-cylinder engine this 2000 Yamaha Grizzly 600 gets hot in the foot and legs, especially during longer trails. The aluminum belt cover as well as the absence of a cooling water jacket for both the head and the cylinder contribute to the issue. 
  • The four-wheeler, which is set to run at a low speed from the beginning, is the main cause of this problem.
  • Beginning Problems: Instead of a starter clutch on the Grizzly’s electronic starter was based on jet skis and a Bendix. The recoil and electric starter configuration made it difficult to get the engine started. When the engine was started, it would be accompanied by a rattle for a short time when the engine began to run. 
  • Yamaha enthusiasts have found this to be similar to the way the Polaris four-wheeler can do.
  • sticky brakes: The rod or the lever of the brake becoming stuck is not uncommon on the Grizzly 600. If this happens, take your lever off the backing plate, then clean it using sandpaper then grease it. 
  • Make use of brake grease that is made of silicone, which can endure temperatures better than regular brake greases and will not cause swelling of the O-ring.

Some other anecdotal issues with Yamaha Grizzly 600 include the quad’s sensitivity to water. Since there is no connection between the cylinder and its outside, the piston is about 1000 degrees when immersed in water. 

Once the water cools down the cylinder it shrinks instantly leading to engine seizure. Another issue is that pistons may be a little short in the 600s. When the piston and cylinder are in extreme wear and tear, the piston could be able to kick out of the bore, and eventually break down. 

Before reaching the point of no return the vehicle could be experiencing a loss in compression and would have stopped running.

Yamaha Grizzly 600 Top Speed

Yamaha Grizzly 600 Top Speed

The top speed of the standard Yamaha Grizzly 700 is 60 mph. Some owners claim they have 62-65 mph however, they recommend that riders follow a few steps to reach this speed:

  • Remove the cover that is on the side to the right, and take the nut off of the shaft.
  • Take the clutch off and look to see if there is a flat spot on your wheels. Replace the clutch as necessary.
  • If the tire-wheel assembly is in good working order, clean, re-lubricate and then put it back together.
  • If you are considering larger tires ensure you consider an accessory clutch system. Some suggestions include EPI, Outlaw, or the equivalent.
  • Make sure that the wheels be able to move freely across the entire range. You might need to experiment to adjust the ratios if you don’t.
  • Check the clearance of the valve. The exhaust valves should take off the nut and set the valve’s gap at .006 or .007 inches. Equally to the intake valves, adjust them in the range of .004 or .005 inches.
  • Utilizing a gauge that can be felt and a feeler gauge, loosen the locknut and then turn the screw to adjust between the valve’s arm and rocker. O-rings made from stock can generally withstand many adjustments.
  • Perform regular oil replacements and spark plug inspections and air filter clean-up to restore power to old Grizzlies.
  • Examine your belt for wear (more than usual when you use your quad extensively for plowing, hunting, and yard duties) then replace the belt with a brand new one when it is worn out.

The following list covers the fundamental aspects you must perform on your four-wheeler in addition to high-performance modifications and other maintenance requirements. Remember that some of these modifications can provide you with some extra kilometers per hour can hinder your low-end performance. 

Experts advise riders to be cautious when fitting knobbies with larger diameters onto their 4x4s since they have proved they are tired bigger than 27 inches which could be harmful to the overall performance of your vehicle. Grease overkill can do damage more than it does good for your bike.

  • Check if the lid of the airbox is clean as a whistle. If it is, it has been recently serviced.
  • The filter that is located in the intake tube must be clean.

  • Take the plug off the rear differential, and then stick with a pencil or stick into the hole. The color of rust or brown is a sign that it’s time to rebuild the rear end.
  • A rear brake must not be stuck. If it is not, you might require replacing the shoes and drum in a set.
  • Bearings on the axle that are loose are typically an indication of gearcase bearings in shot.
  • A soft backfire is typically caused by a low idle mix, an incompletely closed pilot jet, an incorrectly adjusted mixture screw, or an exhaust leak.
  • Pipes that glow seem to be a common occurrence because they are constructed from stainless steel that shines red at a lower temperature than carbon steel that is mild.
