Autolube pump system or pre-mix (recommended ratio of 40:1 if the pump is bypassed). 2. Routine Maintenance and Tune-Up Schedule

If you need help diagnosing a specific mechanical issue, please let me know:

Understanding the precise engineering metrics of your RX 135 is the first step toward successful maintenance. Deviating from these factory parameters can result in power loss or catastrophic engine failure. Powerhead and Cylinder 132cc, 2-stroke, air-cooled, single-cylinder.

In the pantheon of motorcycling legends, few machines command the cult reverence of the Yamaha RX 135. Produced in India from the late 1990s until the mid-2000s, this lightweight, torquey two-stroke became the default "performance bike" for a generation of riders. However, unlike modern four-stroke bikes with sealed ECUs and complex electronics, the RX 135 is a machine of analog simplicity and mechanical temperament. Its heart—a air-cooled, single-cylinder, two-stroke engine—demands a unique blend of art, science, and meticulous discipline to keep alive. The single most important document for achieving this is the . Far more than a pamphlet of torque specs, the service manual is the canonical text of a fading mechanical era: a blueprint, a diagnostic tool, and a philosophical guide to preserving two-stroke soul. Deviating from these factory parameters can result in

Refill with exactly 650ml of fresh SAE 20W-40 oil via the filler cap on the right crankcase cover. 3. Carburetor Tuning and Fuel System Assembly

A: According to technical specifications, the oil capacity is approximately 1.3 liters. However, you should always verify this data and the exact type of oil to use (e.g., viscosity) in your specific service manual.

The owner's manual that came with your bike covers the basics—fuel type, oil changes, and light bulb replacements. The service manual, often called a "workshop manual," is an entirely different beast. It's the same document used by Yamaha's own certified technicians. This is a regulated, licensed instruction manual designed by professional maintenance and service engineers, intended to be the definitive source for all service and repair information.
