Suzuki T250 Hustler / T350 Rebel 1969-1972 OEM Service Manual

Get the exact 32-page factory specifications (P/N unlisted) needed to service, tune, and rebuild the 1969–1972 Suzuki T250 Hustler and T350 Rebel two-stroke engines. Originally published by Suzuki Motor Co. in February 1969, this official PDF reference delivers the raw technical data required for accurate workshop maintenance and repair. By utilizing the exact factory wear limits and testing procedures, you eliminate the guesswork of vintage two-stroke tuning, saving valuable bench time and preventing premature engine failure.

• 21 illustrated special tool references and complete electrical wiring diagrams.
• High-resolution exploded-view engine charts for precise component identification.
• Essential data for Posi-Force lubrication system calibration, ignition timing, and carburetor jetting.
• Step-by-step diagnostic coverage for piston ring end gap clearances, carburetor float level adjustments, gear shifting cam stoppers, clutch axial play measurements, silicon rectifier testing, contact point gap dimensions, and AC generator charging amperage.
• Crucial factory values for oversize piston dimensions, timing gauge diagnostics, neutral brake operation, keystone type piston rings, and engine break-in procedures.

Engine and Transmission Data

Don't guess on critical tolerances. This manual outlines the exact Posi-Force oil pump control cable adjustments and delivery output curves essential for two-stroke longevity. You will find primary engine data covering cylinder head inspections, piston ring installation protocols, and clutch assembly limits, including cork plate thickness standards. Detailed schematics accurately map out the constant-mesh six-speed gear arrangement and neutral brake mechanism. The guide also details step-by-step procedures for calculating cylinder wear and evaluating clutch housing play, providing the technical references usually reserved for professional machine shops and saving you from expensive outsourcing fees during a top-end repair.

Technical Specifications & Electrical Tuning

Tuning a vintage two-stroke requires precision. Performance curves document power and torque thresholds across the operational RPM range. The fuel system section lists specific pilot jet and needle settings for both the T250 and T350 carburetors. For accurate top-end rebuilding, the manual provides standard cylinder bore dimensions and cylinder head warp limits.

The electrical section breaks down rotating alternator specifications and ignition timing sequences calibrated at 24° B.T.D.C. Accessing the manual's detailed instructions for troubleshooting the electrical system—such as checking the silicon rectifier with a multimeter or establishing the charging output—saves hours of costly trial and error at the dealership. Working on vintage motorcycles involves inherent risks, so always cross-reference these factory torque limits, wear tolerances, and safety procedures to ensure reliable operation on the road.
