Asset-ID: Suzuki GSF1200K1, GSF1200K2/SK2, GSF1200, GSF1200S // Service-Level: Four-stroke, air-cooled DOHC engine system architecture // Equipment-Series: 1157 cm³ displacement, 1200 ± 100 r/min idle specification.

System Component Documentation Scope Coverage Details
Engine and Transmission Disassembly/reassembly procedures Complete specifications provided
Fuel system with carburetor architecture Float height, jet sizing, fuel valve operation Reference data documented
Electrical system including charging and ignition Generator output, IC regulator function, spark timing Full technical parameters included

Coverage is segmented into comprehensive chapters addressing engine systems, which documents the intake and exhaust valve mechanisms, then fuel system procedures, which reference carburetor construction and fuel flow regulation, in addition transmission service details that address gearshift fork clearance and drive chain tension, and electrical system inspection covering generator output at 5000 r/min and ignition coil resistance values. Chassis sections provide information on front fork damping adjustment, steering stem bearing service, and brake caliper disassembly sequencing, while the rear suspension chapter references swingarm pivot shaft runout service limits and shock absorber disposal procedures.

Reliably demanding technical content fills 375 pages of factory documentation, where each section delivers component inspection procedures, specification tables, and reassembly guidance for the 4-cylinder Bandit platform. Reference data is included for camshaft journal oil clearance measurement using plastigauge, addressing journal holder I.D. standards of 22.012–22.025 mm. This manual covers valve clearance adjustment methodology, which specifies intake valve clearance of 0.10–0.15 mm when the engine is cold, requiring measurement with the camshaft positioned at reference points A or B. Diagnostic procedures are covered for compression pressure testing, documenting standard pressure of 1250 kPa at the crankshaft and service limits of 875 kPa per cylinder. Wiring diagrams are provided for all market variants (E-02 UK, E-03 USA, E-19 European, E-24 Australia, E-28 Canada, E-33 California, E-54 Israel), detailing signal generator coupler lead wire routing and ignitor power source circuit configuration.

The document includes torque specifications for critical fasteners: clutch sleeve hub nut at 150 N·m, crankshaft journal bearing installation procedures, and engine mounting bolt sequences identifying bolt lengths from 25 mm to 180 mm. Fuel system data includes carburetor I.D. number locations on the carb body, float height adjustment of 13.0 ± 1.0 mm, and pilot screw pre-set positions of 3 turns back. Brake system procedures document master cylinder bore diameter variations (15.870–15.913 mm front, 15.827–15.854 mm rear), brake disc thickness service limits of 4.0 mm front and 4.5 mm rear, and brake caliper piston-to-cylinder clearance specifications. Suspension setting data references front fork spring pre-load adjustment positions (0 maximum to 5 minimum), rear shock absorber mounting nut torque of 50 N·m, and swingarm pivot shaft runout service limit of 0.3 mm.

This manual documents torque specifications for the transmission countershaft bearing retainer at 2.5 N·m, ensuring proper bearing preload, to maintain smooth gear engagement. The service data encompasses electrical system specifications including spark plug gap of 0.6–0.7 mm, ignition coil primary peak voltage greater than 140 V, and battery type YTX12-BS with 36.0 kC (10 Ah) capacity rated at 1.320 specific gravity. PAIR (air supply) system documentation addresses reed valve inspection, vacuum port pressure ranges of 44–65.3 kPa for proper diaphragm operation, and hose routing protocols throughout the intake tract. Tire pressure specifications are provided for solo and dual riding configurations at 250 kPa front and rear, along with tubeless tire sizing of 120/70 ZR17 front and 180/55 ZR17 rear with tread depth limits of 1.6 mm and 2.0 mm respectively. Engine lubrication system charts illustrate oil jet positioning in the upper crankcase, piston cooling passages, and transmission component oiling paths, with engine oil capacity of 3300 ml documented for standard oil changes.

FAQ

What procedures are **necessary** for checking electrical values on the generator? keyboard_arrow_down

13.5 – 15.0 V regulated voltage output must be measured at 5 000 r/min with the lighting switch ON and dimmer switch set to HI. If readings are outside this range, inspect the stator coil, rectifier, and IC regulator mounted within the generator assembly.

Determine the **recommended** calibration settings for the carburetor float height. keyboard_arrow_down

13.0 ± 0.5 mm adjustment is required when the carburetor is inverted and the float arm contacts the needle valve. Bend the float tongue as necessary to achieve the specified level, ensuring proper fuel delivery through all operating conditions.

What specifications must be **calibrated** for throttle cable play measurements? keyboard_arrow_down

2.0 – 4.0 mm clearance at the throttle grip is the standard specification for the pulling cable adjustment. This range prevents binding while maintaining responsive throttle control and must be verified after any carburetor or cable replacement work.

Check the **applicable** torque specifications for the engine sprocket nut installation. keyboard_arrow_down

115 N.m (11.5 kgf.m, 83.0 lb-ft) is the specified tightening torque for the engine sprocket nut assembly. Apply THREAD LOCK SUPER "1303" to the driveshaft threads before installation to prevent loosening during operation.

What does the **exact** fuel tank capacity indicate for reservoir range planning? keyboard_arrow_down

20.0 L (5.2/4.4 US/Imp gal) total capacity with 4.4 L (1.2/1.0 US/Imp gal) reserve ensures adequate fuel range for extended riding. The reserve system activates when main supply depletes, providing approximately 40 miles of emergency riding distance before complete fuel exhaustion occurs.
