The core of the manual—and the RX 135’s soul—is the engine overhaul section. Unlike four-stroke manuals, the two-stroke service guide emphasizes port timing, crankcase sealing, and piston ring orientation. A full-page diagram shows the exact alignment of the piston’s arrow (pointing toward the exhaust port) and the correct staggering of the two ring gaps. Ignoring this single page has led to countless cold seizures, broken rings, and cracked cylinders.
A unique feature of the RX 135 manual is its meticulous treatment of the Yamaha Autolube system. Many owners delete this oil injection system in a misguided attempt to “simplify” the bike, converting it to premix. The manual, however, dedicates an entire chapter to testing the oil pump’s output (measuring oil volume over 200 engine revolutions) and bleeding the system. It argues—correctly, in engineering terms—that the Autolube system provides variable oil delivery based on rpm and throttle position, ensuring both low-smoke idling and high-rpm protection. In this sense, the manual serves as a corrective to folk wisdom, reminding the owner that Yamaha’s engineers were not fools.

Model Coverage: Most manuals cover the RX100, RX135, and RXG variants.
Key Specs: The RX 135 typically produces between 12 to 14 horsepower depending on the variant.
Digital Perk: Modern digital manuals allow you to zoom in on vacuum and wiring diagrams, which is a lifesaver compared to greasy, faded paper books.
If you'd like, I can help you find a specific diagram (like wiring or carb) or summarize a specific torque spec if you tell me what part of the bike you're working on. RX Models | RX135 Service Repair Workshop Manuals
For a two-stroke, maintenance is frequent and non-negotiable. The manual specifies:
The Yamaha RX 135 is not just a motorcycle; it is a moving piece of two-stroke history. Without proper maintenance, that history dissolves into a cloud of blue smoke and broken connecting rods. The core of the manual—and the RX 135’s
The Yamaha RX 135 Service Manual is your only defense. It is the distilled knowledge of every engineer who designed the bike, every race mechanic who tuned it, and every factory technician who fixed it under warranty.
Do not rely on "I think I remember." Do not trust the guy on WhatsApp who says "just tighten it till it feels right."
Find the PDF. Bookmark the torque spec page. Buy a printed copy if you can. And the next time your beloved RX 135 hesitates on a cold morning or pings up a hill, you won’t panic. You’ll walk to your bench, open the manual to the troubleshooting chart, and fix it like a pro.
Because legends never die—they just need proper maintenance.

The longevity of a 2-stroke engine depends heavily on proper lubrication and timely component replacement. Cylinder & Piston
: Standard bores typically last 35,000–50,000 km. Indicators for replacement or reboring include poor throttle response and increased "ringing" noise from the cylinder. Lubrication
: During the run-in period (first 1,000 km), it is recommended to use 40 ml of oil per litre of petrol. For regular use, maintain the oil pump flow as per the manual to prevent engine seizure. Engine Rebuild
: A full rebuild involves replacing all bearings, the crankset, and the bore. Using original parts, such as ART pistons , is highly advised for performance and reliability. Electrical System & Wiring
The RX 135 uses a 12V electrical system. Key components identified in standard wiring diagrams include: Yamaha RX 135 User Manual PDF - Scribd 28 Aug 2015 —

The original RX 135 5-speed is a collectible. If you cannot find OEM pistons, you might use an RX King piston or aftermarket like Art or RDD. The service manual teaches you the stock dimensions (bore: 56mm, stroke: 54mm). With that data, you can safely calculate compression ratios and port heights when fitting non-standard parts.
