Yamaha RA700S, RA700T, RA700AT, RA700BU, RA700BV Service Manual

You’ve got a WaveRaider that won’t start, or a jet pump that’s leaking oil. The aftermarket PDF you found online tells you to “simply remove the carburetor” – no torque specs, no safety warnings, no clue about the oil injection system. That’s how you strip a bolt, crack a housing, and waste a weekend. I’ve seen it a hundred times. What you need is the real deal: Yamaha RA700S, RA700T, RA700AT, RA700BU, RA700BV Service Manual. 270 pages, factory-issued, printed when these machines were on the showroom floor. Not a reprint, not a compilation – the actual OEM document that Yamaha dealers used.

What’s Inside This 270-Page Service Manual

The manual starts with Chapter 1 – General Information, including identification numbers, safety while working, and a list of special tools. Chapter 2 gives you the specs: general specifications, maintenance specs for the engine and electrical system, and the tightening torque table. That torque table is where most aftermarket guides fail. They give you a generic range, not the exact ft-lb for each fastener. Chapter 3 covers periodic inspection and adjustment – maintenance interval chart, control system, fuel system, oil injection system, power unit, electrical, jet pump unit, and general items. If you follow the intervals in that chart, you’ll catch problems before they become expensive repairs.

Tightening Torque: Why the Factory Specs Matter

Torque values are listed in Chapter 2 under the tightening torque section. For the RA700 series, these numbers are specific to each bolt – cylinder head, exhaust ring, flywheel magneto, intermediate shaft, and jet pump impeller. I’ve watched guys guess at these and then wonder why the exhaust ring leaks or the impeller walks off the shaft. The OEM manual gives you the number, and you use a torque wrench that’s been calibrated within the last year. Period. The aftermarket manuals I’ve seen will say “tighten securely” – that’s useless. Page 73 of this manual? That’s where the torque table lives for the power unit. If you’re working on the RA700BU or RA760, the supplementary manuals included in this PDF have their own torque tables.

Fuel System and Carburetor Overhaul – Real Procedures

Chapter 4 – Fuel System – covers the air ventilation hose, water separator, fuel cock, fuel filter, oil tank and fuel tank removal, carburetor removal and overhaul, fuel pump, and oil pump. The carburetor section includes disassembly, cleaning, and reassembly steps with float level specs and jet sizes. The oil injection system is a common headache on these two-stroke WaveRaiders. If you get the oil pump timing off, you’ll seize the engine. The manual shows you the alignment marks and the bleeding procedure. I’ve used this exact procedure on a RA700T that had been sitting for two years – got it running in an afternoon.

Electrical System: Ignition and Charging Diagnostics

Chapter 7 – Electrical System – is where you find the ignition system, starting system, starter motor, charging system, and indication system. The wiring diagrams are in the electrical analysis section. Aftermarket manuals often skip the detailed resistance checks for the CDI unit and the stator. This manual gives you the actual values. I’ve seen a RA700BV that had a no-spark condition – the manual led me to a bad pickup coil in 20 minutes. The electrical components section lists part numbers and test procedures. If you’re troubleshooting a charging issue, the charging system section has load test specs and rectifier checks.

Who Needs This Manual

If you own a Yamaha WaveRaider RA700S, RA700T, RA700AT, RA700BU, or RA700BV – from model years 1994 through 1997 – this is your manual. It also covers the RA760U and RA1100T/U models, but the primary focus is the 700 series. Whether you’re a home garage mechanic or a shop tech, this manual will keep you from guessing. The supplementary manuals for RA700BU and RA760 are included in the same PDF, so you get the updates for later models. If you’re working on a different Yamaha, check out the Yamaha XT350 1985 Service Manual – Factory Specs & Torque Data for a similar engine layout, or the Yamaha YZF600RJ 1996 Service Manual – Factory Specs & Repairs for a sportbike electrical system. For a full rebuild on a later model, the Yamaha YZF-R1S YZF-R1SC 2003 Service Manual – Factory Torque Specs is a good reference.

Source Authenticity: OEM Factory Print vs. Aftermarket

This manual was printed by Yamaha Motor Co., Ltd. in 1996 – first edition, LIT-18616-RA-00. It’s a scanned PDF of the original dealer service manual. The cover says “SERVICE MANUAL” and it includes the preface that warns against using the manual without proper mechanical knowledge. That’s a real OEM document. Aftermarket manuals often omit the safety warnings and the special tool lists. This one has a full chapter on safety while working and a list of special tools. The wiring diagrams are factory schematics, not redrawn by a third party. The jet pump unit chapter (Chapter 6) shows the impeller and drive shaft removal with exact shim dimensions. You won’t find that in a Haynes manual. The bilge system and cooling system diagrams are also OEM. The indexing is precise – each chapter starts with a table of contents. The RA700BU supplementary manual at the end covers the changes made for that model, including the carburetor and fuel pump differences. This is the document that Yamaha dealers paid for. It’s the same one I used when I was a young tech in San Antonio.

Frequently Asked Questions

Does this manual cover the RA700AT model?

Yes. The RA700AT is listed in the title and in the preface. The manual covers RA700S, RA700T, RA700AT, RA700BU, and RA700BV. The RA700AT is a ’95 model, and the procedures are identical to the RA700T with minor trim differences. The torque specs and electrical diagrams apply.

What about the jet pump – is there a rebuild procedure?

Chapter 6 – Jet Pump Unit – covers removal, disassembly of the nozzle, duct, intake, impeller, and drive shaft. It also includes the cooling and bilge system. The supplementary manual for RA700BU has additional jet pump unit info. The torque for the impeller nut is in the torque table.

Are the wiring diagrams in color?

No. This is a black-and-white scan of the original manual. But the wire colors are labeled clearly in the diagrams. The electrical analysis section in Chapter 7 includes resistance values and continuity checks. The diagrams are factory-correct, and I’ve used them to trace a short in the indication system on a RA700BV.

Can I use this manual to rebuild the engine?

Yes. Chapter 5 – Power Unit – covers the engine unit removal, reed valve, exhaust ring, exhaust chamber, muffler, cylinder head, cylinder, piston, flywheel magneto, base, electrical unit, crankcase, crankshaft, intermediate shaft, and housing. The procedures include step-by-step disassembly and assembly with torque values. The RA700BU supplementary manual includes cylinder head and piston specs for that model. This manual is the only source you need for a full engine rebuild on the 700 series.

That’s the bottom line. If you’re going to work on a Yamaha WaveRaider 700, don’t trust a generic manual. Get the factory document that has the torque values, the wiring diagrams, and the safety warnings that keep you from making a mistake. Access the Factory Manual and put it on your tablet or print it out. You’ll save time and avoid the kind of frustration that sends a machine to the scrap pile. The jet pump unit functions similarly to a Manual Transmission in terms of power transfer, and the steering system uses cables that need periodic adjustment – both covered in the manual. For other two-stroke watercraft, the principles are the same, but the specs are different – that’s why you need the OEM manual. If you’re looking for a similar document for a different vehicle, the Manual Transmission section in our shop manuals collection might help you find the right one.
