Став двойным сузуководом с удивлением обнаружил, что этот раздел вообще пустой.
Т.е. семейство мотоциклов Intruder оказалось абсолютно забытым. Надеюсь всё же это будет со временем исправленно.
Сам же я приобрёл чудестный мотоцикл Сузуки Десперадо и по нему мной было собранно несколько ссылок, которыми и хочу поделиться.

Мануал по Мародёру, от которого Десперадо не сильно отличается:

Suzuki VZ Service Manual

Год выпуска: 1997
Автор: Suzuki SD
Жанр: мотомануал
Издательство: Suzuki Service Department
Формат: PDF
Язык: Английский
Описание: Мануал на мотоциклы Suzuki VZ. Данное руководство изначально написано для Suzuki Marauder 97-02, однако, с успехом может использоваться при обслуживании Suzuki Desperado (благо отличия, в основном, в объеме горшка) — проверено на практике лично, кому нужна помощь — стучите в аську. Детально расписаны операции по всем основным узлам мотоцикла.
Информация для братьев-байкеров — найти мануал на Desperado на английском нереально — это модель для внутреннего рынка японии. Про русский и не говорю. А этот мануал подходит.

Page 161: Fuse

5-4 FI SYSTEM • When connecting meter probe from the terminal side of the coupler where (connection from harness side not being possi- ble), use extra care not to force and cause the male terminal to bend or the female terminal to open. Connect the probe as shown to avoid opening of female ter- minal.
Page 162
FI SYSTEM 5-5 Ignition S/W • When disconnecting and connecting the ECM couplers, make sure to turn OFF the ignition switch, or electronic parts may get damaged. INCORRECT • Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will damage the components of the FI system instantly when reverse power is applied.
Page 163: Electrical Circuit Inspection Procedure

5-6 FI SYSTEM ELECTRICAL CIRCUIT INSPECTION PROCEDURE While there are various methods for electrical circuit inspection, described here is a general method to check for open and short circuit using an ohmmeter and a voltmeter. OPEN CIRCUIT CHECK Possible causes for the open circuit are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.

5-8 FI SYSTEM SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND) • Disconnect the negative cable from the battery. To other • Disconnect the connectors/couplers at both ends of the circuit parts to be checked. NOTE: If the circuit to be checked branches to other parts as shown, disconnect all connectors/couplers of those parts.
Page 166: Using The Multi-Circuit Tester

FI SYSTEM 5-9 USING THE MULTI-CIRCUIT TESTER • Use the Suzuki multi-circuit tester (09900-25008). • Use well-charged batteries in the tester. • Be sure to set the tester to the correct testing range. USING THE TESTER MULTI-CIRCUIT TESTER • Incorrectly connecting the + and — probes may cause the inside of the tester to burnout.
Page 167: Fi System Technical Features

5-10 FI SYSTEM FI SYSTEM TECHNICAL FEATURES INJECTION TIME (INJECTION VOLUME) The factors to determine the injection time include the basic fuel injection time which is calculated on the basis of the intake air pressure, engine speed and throttle opening angle, and various compensations. These compensations are determined according to the signals from various sensors that detect the engine and driving conditions.
Page 168: Compensation Of Injection Time (Volume)

FI SYSTEM 5-11 COMPENSATION OF INJECTION TIME (VOLUME) The following different signals are output from the respective sensors for compensation of the fuel injection time (volume). SIGNAL DESCRIPTION ENGINE COOLANT TEMPERATURE SEN- When engine coolant temperature is low, injection time (vol- SOR SIGNAL ume) is increased.

Page 346: Tire And Wheel

8-66 CHASSIS TIRE AND WHEEL TIRE REMOVAL The most critical factor of tubeless tire is the seal between the wheel rim and the tire bead. For this reason, it is recommended to use a tire changer that can satisfy this sealing requirement and can make the operation efficient as well as functional.
Page 347: Valve Inspection

CHASSIS 8-67 VALVE INSPECTION Inspect the valve after the tire is removed from the rim. Replace the valve with a new one if the seal A rubber is peeling or has damage. NOTE: If the external appearance of the valve shows no abnormal con- dition, removing of the valve is not necessary.
Page 348: Tire Installation

8-68 CHASSIS TIRE INSTALLATION • Apply tire lubricant to the tire bead. • When installing the tire onto the wheel, observe the following points.  * Do not reuse the valve which has been once removed. * Never use oil, grease or gasoline on the tire bead in place of tire lubricant.
Page 349: Balancer Weight Installation

CHASSIS 8-69 • In this condition, check the “rim line” B cast on the tire side walls. The line must be equidistant from the wheel rim all around. If the distance between the rim line and wheel rim varies, this indicates that the bead is not properly seated. If this is the case, deflate the tire completely and unseat the bead for both sides.

Уважаемые начинающие чопперюги. Чтобы не плодить каждый раз тем, сообщаю вам, что на внутреяпонские модели чопперов, к коим относятся ВСЕ малокубатурники, НИКОГДА НЕ БЫЛО И НЕ БУДЕТ мануалов хотя бы даже на английском языке. Не нужно их искать или просить предоставить, так как их попросту нет. Примите это как факт.

Для того чтобы разобраться что же делать, предлагаю знающим писать прямое соответствие мануалов более кубатурных собратьев, которые помогут информацией и для маленьких чопперов.

Ну и собственно первая помощь от меня:
Kawasaki Vulcan 400-A/C/D соответствует Vulcan 800-A/C/D (во всём, только есть некоторые расхождения по двигателю, и то не значительные и скорее всего вам не понадобятся), это относится к моделям с V-образным двигателем.
Yamaha Virago 400 соответствует Virago 535

P.S. Просьба модератора прилепить тему сверху.
