Information about the Polaris Magnum 500

It is the Polaris Magnum 500 is a utility ATV, which was introduced before its predecessors, Magnum 300 and 325 versions. 

It was introduced in the market from 1999 until 2002 the 500-class machine was initially conceived as an experimental vehicle.

Polaris wanted to determine whether it could compete head-to-head against Honda’s FourTrax Foreman TRX450. In this case, this Magnum 500 was able to succeed. 

The first decade of 2000 proved that the 450-500-class quads were very popular in those in the sports ATV segment.

But, people preferred smaller displacement and a size that was more suitable for the four-wheelers that were used for utility purposes.

At an initial price of $6,499, this Magnum 500 offered more than its value. It was a favorite of those who wanted an average-sized 4×4 that could be used for doing ranch work as well as leisure-related tasks. 

In addition, it offered remarkable capacity for hauling, a clever storage system, as well as ample space for taller riders.

 The added weight, though not favored by many off-roaders, increased the stability of the vehicle and increased the confidence of the rider.

Despite its relatively short production time, The Magnum received updates that eventually benefited the smaller variants. 

Since 300- and 330-class Magnums were eventually given the ATV’s 34-mm carb as well as displacement of 329 cubic centimeters the power output, as well as the performance of the flow of air to the motor, was improved dramatically. These improvements also led to improved control, shifting, and handling.

Year – Trim – Model Number List Price Retail/Trade-In Values
1999 Polaris Magnum 500 $6,499 $850 – $1,120

They did however come in red, blue, Hunter Green, and yellow. Used vehicles that are more than $2000 are in great condition that has low mileage/hours, with well-maintained body panels. 

The majority of the vehicles you see on auctions and trader websites are Magnums from 1999, but it is possible to find 2000 and 2002 models. 

It is interesting to note that 1999 trims seem to have the highest value and can cost up to $2,970. The maximum cost for the latest models can be as low as $2,300.

Some of the issues to be expected from a second-hand Magnum include dead batteries and a malfunctioning odometer or damaged plastics.

In terms of mileage used Magnums typically have more than 600 hours and 2,400 miles. 

Therefore, if you find one with a lot of mileage and hours, do not take it for granted! Make sure you inquire about the past of the car in case, for example, it’s been parked for too long out in the open, in the garage of the previous owner, or was severely damaged – as it could indicate possible problems with the carb or tranny over the long term.

Polaris Magnum 500 Problems

This section addresses common problems that are encountered with Magnum owners (especially those who bought second-hand quads). 

Although the following pieces of information are taken from the manual, it’s recommended to have an original copy. 

A manual for the owner to refer to when you need to repair or service your vehicle can greatly aid in the maintenance and longevity of your wheeler.

Does Not Run

As with all ATVs like all other ATVs, like all ATVs, the Magnum 500 has three things that must be examined when there is a problem with no-run the engine, fuel system, and ignition. 

The fuel system contains the majority of components that require inspection, like contamination in fuel lines/filters limitations in the tank valve, fuel vent, and the pump or even flooding in the engine. Compression is said to be the most straightforward to identify in the event of an issue.

However, because some off-roaders decide not to purchase an instruction manual for their vehicle, determining the accuracy of compression according to the specs can be an uninitiated guessing game.

If you notice any symptoms that are emitted through the equipment, you could have to examine electronic components in the first or second. 

If they are found to be the cause The problem usually can be traced to a corroded spark plug, low-voltage or damaged battery, or damaged terminals or coils.

 In other cases, you might need to re-looking at the fuel system, or wait for another set of signs will appear after the initial troubleshooting.

Idles, But Does Not Rev Up

The no-rev issue is usually encountered when a running issue is resolved. At this point, you’ve already done an examination of the mentioned systems. So, you’ll have to examine those air intake, control, jetting, and exhaust systems. 

Check that airflow to the engine isn’t restricted, the controls aren’t restricting the speed of your vehicle and that the throttle cables aren’t broken, and that the ignition timing is accurate.

Engine Overheats

Because of the many different things ATVs can be used for, this is practically a requirement for all owners. 

But that doesn’t mean that you can ignore the issue. If it happens often, it is likely you have a problem with the cooling system of your vehicle (radiator specifically) hot light circuit, or the fuel pump.

 The incorrect temperature setting for your spark plug as well as leaks in the system that are not noticed is also possible causes.

These problems are far from the plethora of issues faced by Magnum owners as a whole. 

If you’re looking to find out what you can be expecting buy an owner’s guide. Also, be sure to go to Polaris forums since there is an abundance of information available which can assist you in making your four-wheeler run more smoothly. 

Keep an eye out for any problems after the resolution of the above-mentioned issues, because they could suggest the need for a rebuilt kit, exhaust cam lobe repair, or help from an experienced mechanic.
