1999 Yamaha YFZ350: Quick Overview

The 1999 Yamaha YFZ350 Banshee, a revered high-performance ATV, comes with a distinctive set of specifications:

• Engine: 347cc (80mm x 69mm bore x stroke), liquid-cooled, two-stroke, twin-cylinder, reed valve induction.
• Horsepower: Stock output typically ranges from 34-36 horsepower at the rear wheels, though engine modifications can easily push this to 50-70+ HP.
• Fuel Economy: Quite poor. Due to its high-revving, two-stroke nature and carbureted fuel system, fuel economy is often below 20 MPG, heavily dependent on riding style, jetting, and modifications. It also requires a premix of high-octane gasoline and two-stroke oil.
• 0-60 Times: While not officially published for ATVs, a stock Banshee is estimated to achieve 0-60 mph in the 4-6 second range. Modified versions can be significantly faster, rivaling some sports cars.
• Towing Capacity: The Banshee is a pure sport quad and not designed for towing. Its towing capacity is negligible and not recommended.
• Trim-Level Features: The YFZ350 primarily came as one core model, commonly known as the Banshee, with color variations. Standard features included:
  
  • Dual Mikuni carbs for precise fuel delivery.
  • Twin expansion chamber exhaust system for optimal two-stroke performance.
  • Independent double A-arm front suspension with adjustable preload.
  • Swingarm rear suspension with a single monoshock, also with adjustable preload.
  • Dual hydraulic disc brakes on the front, and a single hydraulic disc brake on the rear.
  • Manual clutch with a 6-speed constant mesh transmission.
  • Reliable chain final drive.
  • Kick start mechanism (no electric start on stock models).
  • Aggressive sport tires designed for traction and handling.
  • Durable steel frame construction.
  • Minimal instrumentation, often limited to an ignition kill switch and basic indicator lights.
  • No reverse gear from the factory, a common owner complaint addressed by aftermarket kits.
  • Headlights and a taillight for basic visibility.

What Problems Does the 1999 Yamaha YFZ350 Have?

• Engine Wear: The most common issue is engine wear, particularly the top-end (pistons, rings). Hard riding necessitates more frequent rebuilds, often every 50-100 hours, to maintain peak performance and prevent catastrophic failure. Bottom-end (crankshaft and bearings) also requires attention over time, typically after multiple top-end refreshes.
• Jetting Sensitivity: Being carbureted, proper jetting is critical. Incorrect jetting can lead to overheating, poor performance, or even engine seizure. Riders often struggle to find the 'perfect' jetting for varying altitudes, temperatures, or modifications.
• Clutch Issues: Aggressive riding style, which the Banshee encourages, often leads to accelerated clutch plate wear, requiring more frequent replacement than in milder ATVs.
• Electrical Components: Stators and CDI units can fail over time, leading to intermittent spark issues or a complete loss of ignition. These are common failures on older ATVs.
• Suspension Components: Bushings and bearings in the A-arms and swingarm are prone to wear, especially if exposed to mud and water without regular cleaning and greasing. This leads to loose handling and reduced stability.
• Exhaust Leaks: The twin exhaust system can develop leaks at the expansion chamber joints or where it meets the cylinder, reducing power and creating excessive noise.
• Frame Cracks: While not a widespread issue on stock, well-maintained Banshees, heavily abused units, or those with extreme modifications, can develop frame cracks around stress points, particularly near the swingarm pivot or engine mounts.

What Technology & Safety Features are Included?

• Built-in Tech: Its "tech" was primarily mechanical. It featured a liquid-cooling system to manage the heat of its twin two-stroke engine and reed valve induction for efficient fuel/air mixture. Fuel delivery was handled by twin Mikuni carburetors, requiring manual adjustment for optimal performance across varying conditions. Instrumentation was minimal, often limited to an ignition kill switch, a headlight switch, and possibly a neutral indicator light, with no standard speedometer, odometer, or fuel gauge.
• Entertainment: The Banshee's primary form of entertainment was the raw, exhilarating sound and feel of its powerful two-stroke engine. No integrated audio systems or digital displays were present.
• Driver-Assistance: None. The Banshee offered a pure, unassisted riding experience, demanding full rider skill and attention. There were no electronic aids like traction control, power steering, or ride modes.
• Safety Features: Safety features were basic but effective for the era:
  
  • Brakes: Dual hydraulic disc brakes up front and a single hydraulic disc in the rear provided strong stopping power.
  • Lighting: Headlights and a taillight were standard for basic visibility.
  • Kill Switch: A handlebar-mounted kill switch allowed for immediate engine shutdown in emergencies.
  • Parking Brake: A manual lever-style parking brake was included.
• Optional Features: From the factory, options were practically non-existent beyond color schemes. However, the aftermarket scene for the Banshee is immense, offering a vast array of "optional" upgrades:
  
  • Performance: Aftermarket exhaust systems, larger carburetors, porting, stroker cranks, high-performance CDI units, and big bore kits significantly boost power.
  • Handling/Suspension: Upgraded shocks (e.g., Fox, Elka), extended A-arms and swingarms, wider axles, and steering stabilizers enhance handling.
  • Rider Comfort/Safety: Nerf bars, grab bars, upgraded handlebars, and stronger tires are common additions.
  • Convenience: Aftermarket reverse kits are popular to address the factory's lack of reverse. Small digital hour meters or speedometers are sometimes added.
• Crash-Test Ratings: Not applicable. ATVs are not subjected to crash-test ratings like passenger vehicles. Rider safety depends entirely on proper protective gear and responsible riding practices.

How Does the 1999 Yamaha YFZ350 Compare to Other Motorcycle?

• Key Rivals:
  
  • Honda TRX250R (2-stroke): The 250R, a single-cylinder two-stroke, was revered for its superior handling and legendary reliability. While less powerful than the Banshee in raw acceleration, it was often considered a more refined and easier-to-handle race machine. Used prices for clean 250Rs often match or exceed Banshees due to their collectibility.
  • Suzuki LT500R Quadzilla (2-stroke): A true monster, the 500cc two-stroke Quadzilla offered unparalleled straight-line speed, dwarfing the Banshee's power. However, it was heavier, less agile, and far rarer, making parts and maintenance more challenging.
  • Yamaha YFZ450 (4-stroke, later model): Though introduced later (2004), the YFZ450 became the Banshee's spiritual successor. It offered modern suspension, electric start, reverse, and a broad, usable 4-stroke powerband. A YFZ450 would typically outperform a stock Banshee in overall race conditions due to superior handling and usable power, but lacked the Banshee's raw, two-stroke punch.
• Performance: The Banshee excels in raw, blistering straight-line acceleration and top speed among its two-stroke peers (excluding the Quadzilla). Its twin-cylinder two-stroke engine delivers a unique, thrilling powerband. Modern four-stroke sport quads like the YFZ450 or Honda TRX450R offer more linear power delivery, better low-end torque, and generally superior handling due to more advanced suspension designs.
• Features: The Banshee is spartan. Its rivals from the same era, like the Honda 250R, were similarly basic. Later four-stroke sport quads introduced conveniences like electric start, reverse gear, and more sophisticated, adjustable suspension.
• Reliability: All high-performance two-strokes demand diligent maintenance. The Banshee is reliable *if* meticulously maintained, including regular top-end rebuilds. The Honda 250R is often cited as being marginally more robust in stock form due to its simpler single-cylinder design. Modern four-strokes typically require less frequent engine rebuilds but still demand consistent maintenance.
• Price: New, they were competitive. Used, the Banshee defies typical depreciation, often commanding prices similar to or even higher than some modern 450cc sport quads, a testament to its cult status and enduring appeal.
• Alternatives:
  
  • For raw 2-stroke power and nostalgia: Another well-maintained Banshee, or if you can find and maintain it, a Suzuki LT500R.
  • For modern performance, better handling, and slightly easier maintenance (compared to 2-strokes): Consider a used Yamaha YFZ450 or Honda TRX450R (mid-2000s models).
  • For collectibility, superb handling, and legendary status (with less power than a Banshee): A Honda TRX250R.
