What Makes the 2007 Polaris Predator 500 a Modern Classic?
Before we dive into the nuts and bolts, it’s worth appreciating what makes this machine special. Unlike many of its rivals, the Predator 500 brought a unique blend of features to the table, making it a formidable competitor in the high-performance sport quad market.
The heart of the beast is a potent 499cc, dual overhead cam (DOHC), liquid-cooled single-cylinder engine built by Fuji Heavy Industries. This isn’t just any engine; it’s known for its strong mid-range pull and impressive top-end rush. This is one of the key benefits of the 2007 Polaris Predator 500—a powerband that’s both thrilling for experts and manageable for experienced riders.
Polaris didn’t stop there. They equipped it with premium, long-travel Fox Racing shocks, a precise-shifting 5-speed manual transmission (with that famously tricky reverse), and aggressive styling that still looks sharp today. It was built to compete, and it did.
The Most Common Problems with the 2007 Polaris Predator 500 (And How to Fix Them)
No machine is perfect, and the Predator has its well-documented quirks. Knowing what to look for is half the battle. This section is your field guide to diagnosing and fixing the most frequent issues. Tackling these common problems with the 2007 Polaris Predator 500 will keep you on the trail and out of the shop.
Electrical Gremlins: Stator and Wiring Woes
If your Predator has a weak spark, difficulty starting, or a battery that won’t stay charged, the first suspect is often the stator. The OEM stators were a known weak point.
Symptoms to watch for:
- Battery dies quickly, even after a full charge.
- Headlights dim noticeably when you rev the engine.
- Weak or intermittent spark when testing the plug.
- Engine cuts out randomly when it gets hot.
The Fix: Use a multimeter to test the stator’s output according to your service manual’s specifications. If it fails the test, don’t waste your time with another OEM unit. Invest in a quality aftermarket stator from a reputable brand like Ricky Stator or Ricks Motorsport Electrics. They are built with better materials and are far more reliable.
Carburetor Conundrums: Bogging and Starting Issues
The 38mm Mikuni BSR carburetor is a solid performer but can be finicky if neglected. Issues like bogging on acceleration, hard starting, or a hanging idle often point to a dirty or poorly tuned carb.
The Fix: A thorough carb clean is your first step. You’ll need a can of carb cleaner, some small brushes, and compressed air.
- Carefully remove the carburetor from the machine.
- Disassemble it on a clean workbench, taking pictures as you go.
- Pay special attention to the pilot jet and main jet—they have tiny orifices that clog easily. Use compressed air, never a metal wire, to clear them.
- Ensure the float is set to the correct height. An incorrect float level can cause it to run too rich or too lean.
This is also a great time to consider a jet kit from a company like Dynojet, especially if you’ve added an aftermarket exhaust or air filter.
The Infamous Reverse Gear Issue
Yes, the stories are true. The reverse gear mechanism on the Predator is a notorious weak point. The stock setup uses a small chain and gears that are prone to breaking, especially if engaged forcefully. If you hear grinding or your reverse simply stops working, this is likely the cause.
The Fix: Several companies make heavy-duty aftermarket reverse kits that replace the fragile stock components with a much more robust gear-driven system. This is not a simple bolt-on job and requires splitting the engine cases. This is a task for an experienced DIY mechanic or a professional shop. If your reverse is still working, the best practice is to always be at a complete stop and engage it gently.
Your Essential 2007 Polaris Predator 500 Care Guide
The secret to a long-lasting, reliable quad is consistent, preventative maintenance. Following this 2007 Polaris Predator 500 care guide will save you a ton of headaches down the road. These are the 2007 Polaris Predator 500 best practices that every owner should live by.
Pre-Ride Inspection Checklist (T-CLOCS)
Before every single ride, take five minutes to run through this checklist. It could save you from a breakdown or, worse, an accident.
- T – Tires & Wheels: Check air pressure and look for any damage or cuts. Grab the wheels and check for loose bearings.
- C – Controls & Cables: Check throttle and clutch lever action for smoothness. Ensure brake levers and pedal feel firm.
- L – Lights & Electrics: Test your headlight, taillight, and kill switch.
- O – Oil & Fluids: Check engine oil level. Check coolant level in the overflow bottle. Look for any leaks.
- C – Chassis & Suspension: Check your chain for proper tension (about 1-1.5 inches of slack). Look over the frame for any cracks, especially around welds and suspension mounts.
- S – Stands: Not applicable here, but it’s part of the acronym for motorcycles!
Routine Maintenance Schedule
Stick to a regular schedule for key maintenance tasks. Your owner’s manual has the official intervals, but for aggressive off-road use, it’s wise to be more frequent.
- Engine Oil & Filter: Change every 10-15 hours of riding. Use a high-quality synthetic oil like Polaris PS-4 or a comparable 0W-40 synthetic designed for powersports engines.
- Air Filter: Clean and re-oil your air filter after every dusty ride. A dirty air filter is the fastest way to kill engine performance and longevity. This is one of the most important 2007 polaris predator 500 tips we can give you.
- Chain Maintenance: Clean and lubricate your chain after every ride, especially after washing or riding in wet conditions. Check tension regularly.
- Valve Check: Check your valve clearances every 50 hours. Tight valves can lead to hard starting and eventually catastrophic engine damage.
How to Get More Grunt: Smart Performance Mods
Ready to unlock even more performance from your Predator? The key is to choose mods that work together as a system. Here’s how to 2007 Polaris Predator 500 performance can be safely and effectively improved.
The “Big 3”: Exhaust, Intake, and Jetting
This is the classic, tried-and-true formula for more power. A full aftermarket exhaust system (like one from Yoshimura, FMF, or HMF) allows the engine to breathe out more efficiently. A high-flow air filter and intake tube (like a K&N or Pro-Design kit) lets it breathe in more easily. To compensate for this increased airflow, you must re-jet the carburetor. Skipping the re-jetting will cause a lean condition that can severely damage your engine.
Suspension Upgrades for a Better Ride
The stock Fox shocks are great, but they can be made even better. Having them professionally re-valved and re-sprung for your specific weight and riding style is one of the best mods you can make. It will transform the handling, making the ride plusher over bumps and more stable at high speeds.
Riding Green: Sustainable and Eco-Friendly 2007 Polaris Predator 500 Practices

When washing your quad, do so on a grassy area or at a car wash with proper drainage to prevent soap and grime from entering storm drains.
Proper fluid disposal is also critical. Take your used engine oil, coolant, and other fluids to an auto parts store or a local recycling center. Never, ever dump them on the ground or down a drain.
