2001 Yamaha TW200N, TW200NC Supplementary Service Manual (P/N LIT-11616-05-93, LIT-11616-14-43)

• Coverage and document set: Covers the 2001 Yamaha TW200N/TW200NC, identified inside the supplement as TW200EN/TW200ENC, with model codes 5FY8 and 5FY9. The two PDFs total 372 pages: a 276-page combined reference manual and a 96-page 2001 supplement. Publication numbers are LIT-11616-05-93, LIT-11616-06-26, and LIT-11616-14-43.
• Full engine repair coverage spans engine removal, cylinder-head and valve work, piston and cylinder inspection, clutch and oil-pump service, crankcase splitting, crankshaft and balancer work, transmission and shifter repair, starter drive, and final engine assembly and installation.
• For the 2001 models, Yamaha adds timing-chain tensioner inspection and installation, stator and pickup-coil service, AC-magneto removal, and MV28/TEIKEI carburetor removal, teardown, inspection, reassembly, installation, and fuel-level adjustment.
• Front-end procedures address the front wheel and brake disc, pad replacement, master-cylinder and caliper overhaul, hydraulic filling and bleeding, fork-leg removal, and steering-head bearing installation.
• Electrical diagnosis covers switch continuity, no-spark troubleshooting, starter cut-off operation, starter relay and diode tests, horn and lighting faults, and turn-signal, brake-light, and neutral-indicator checks.
• Reference material includes model-specific wiring diagrams, system circuit diagrams, cable-routing drawings, lubrication layouts, exploded assemblies with job-order charts, component torque tables, wear limits, adjustment data, and electrical test specifications.

Yamaha prepared these publications primarily for its dealers and qualified mechanics, and it states that users need a basic understanding of motorcycle repair. The set is best suited to technicians and experienced owners who can follow factory job charts and use the specified measuring and test equipment; it does not teach basic shop practice.

How the 2001 Supplement Uses the Earlier Manuals

The 2001 publication is a true supplement, not a stand-alone repair manual. Its foreword directs the mechanic to use it with the 1987 TW200T/TC Service Manual and the 1988 TW200EU/EUC Supplementary Service Manual. Those earlier references are supplied together in the 276-page PDF, while the 96-page file records the service information and specifications changed for the 5FY-series machines. The older sections carry 2JY/2JX and 2YG/3AW model identifiers; their purpose here is to provide the base procedures Yamaha calls out for the 2001 models.

The 2001 supplement is the first edition dated November 2000. The cover names TW200N/TW200NC, while specification tables and diagrams use TW200EN/TW200ENC. That naming difference appears within the Yamaha publication itself, and both sets of names point to model codes 5FY8 and 5FY9.

2001 Engine and Carburetor Changes

Its specification section identifies a 196cc air-cooled, four-stroke SOHC single and the MV28/TEIKEI carburetor. It separates the two model configurations by carburetor ID—5FY10 for TW200EN and 5FY00 for TW200ENC—and supplies different main-jet, jet-needle position, and pilot-air-jet data where required. The carburetor chapter reaches beyond a settings chart: it covers the piston valve and diaphragm, starter plunger, coasting enricher, needle valve and seat, float, jets, fuel passages, hoses, assembly checks, and fuel-level measurement with gauge YM-01312-A.

Engine-specific update pages show cylinder-head removal around the automatic timing-chain tensioner, tensioner inspection and reset for installation, and the revised stator-coil and pickup-coil assembly. The AC-magneto exploded view also identifies the starter idle gear, starter wheel gear, rollers, spring caps, springs, and starter clutch.

Disc Brake, Front End, and Electrical Work

The 2001 chassis material reflects the single front disc/rear drum layout. It covers disc condition, thickness, and deflection checks; front-wheel removal and installation; pad service; master-cylinder and caliper disassembly, inspection, reassembly, hose routing, bleeding, and final lever checks. Yamaha specifically warns that solvent on internal brake parts can swell and distort the caliper piston seals. Securely support the motorcycle during front-end work, keep the hydraulic system clean, and confirm brake operation after bleeding.

Electrical coverage is organized around the TW200EN/TW200ENC wiring diagram plus ignition, electric-starting, and signaling circuit diagrams. Fault-isolation sequences test the fuse and battery before moving through the spark plug, ignition and pickup coils, source coil, neutral relay, diode, starter relay, switches, horn, and lamps. Named test equipment includes pocket tester YU-03112 and dynamic spark tester YM-34487; the base engine procedures also call out clutch holder YM-91042, valve spring compressor YM-04019, and rotor puller YM-01080.

The earlier chassis chapter adds front-fork overhaul, steering and handlebar service, wheel-bearing work, drive-chain and sprocket inspection, and the gas-charged Monocross “De Carbon” rear shock and swingarm. Yamaha warns against opening or heating that shock assembly: pressure can make the unit rupture, while damage to its cylinder or piston-rod surfaces can impair damping.
