Quick 60-Second Pre-Ride Checklist for the motorcycle listed in PreRide Checklist for a 1973 Yamaha TX650 Motorcycle
- Key on & confirm lights: headlight, tail/brake, and turn signals illuminate.
- Front and rear brake lever/pedal feelfirm, not spongy.
- Visual tire check for correct pressure, cuts, or flattened spots.
- Chain tension within a couple inches of manufacturer play & lightly lubricated.
- Oil level at sight glass or dipstick; no fresh leaks under the engine.
- Throttle snaps back when released; clutch engages smoothly.
- Kickstand retracts; mirrors positioned for a clear rear view.
Tires and Wheels
The 1973 Yamaha TX650 is a street bike that responds to proper rubber. Inspect both front and rear tires for even tread wear, embedded objects and sidewall cuts. Pay attention to any flat spots or cracking in older tires; period bikes often retain original rims that reveal slow leaks at the valve stem.
Check tire pressure with a gauge cold. Use pressure appropriate for the TX650's twinseat street setup rather than sport or touring numbers. Spin each wheel while holding the bike upright and listen for rubbing noises or wobbles that indicate a bent rim or loose spokes. Any irregular vibration through the bars or seat at low speeds should prompt a closer look before leaving.
Brakes
Braking confidence is essential on the classic TX650. Squeeze the front lever and press the rear pedal to confirm firm, predictable resistance. A lever that reaches the grip with little pressure or a soft pedal often signals air in the line or worn friction material.
Visually inspect pads or shoes for remaining lining thickness and scan brake lines for cracks or seepage. Check the level in the master cylinder reservoir for the front brake; top off with the correct DOT fluid if low and clean any spilled fluid from paint or rubber. Brake performance is not the place to shortcuttested, solid stops are a must before setting out.
Chain / Drivetrain
The 1973 Yamaha TX650 uses a conventional roller chain. Confirm freeplay at the rear axle midpointthere should be a small amount of up/down movement yet not so loose that the chain slaps at idle. Adjust tension at the axle adjusters in small increments, keep the rear wheel aligned, and torque fasteners securely.
Lubricate the chain with a suitable chain lube, concentrating on the rollers and not throwing excess onto tires. Inspect sprocket teeth for hooked or uneven wear; replace chain and sprockets as a matched set if wear is apparent. Listen for clunks when you slowly roll the bikethose noises can indicate stiff links or worn components.
Fluids
Check engine oil level with the bike on its centerstand or held upright. The TX650's aircooled twin benefits from regular oil checks; low oil will lead to accelerated wear and overheating. Look beneath the engine for fresh drips that might indicate a leaking gasket or loose drain plug.
Brake fluid levels should be visible in the reservoirs and remain clear. If the bike has had a modern conversion to a sealed coolant system, verify coolant level and conditionbut most original TX650s are aircooled, so focus on oil and brake fluid. Replace fluids when contaminated or dark rather than just topping off.
Controls and Lights
Twist the throttle to ensure instant return to idlesticky throttle cables are common on older bikes and must be freed up before riding. Pull the clutch lever and check for smooth travel and positive engagement, and operate each gear to confirm the transmission selects cleanly with the engine running.
Cycle the headlight, high beam, tail/brake, and both turn signals. Listen for a clicker and inspect that each bulb illuminates brightly. Replace dim bulbs and ensure wiring connectors are snug; loose connections can act up under vibration.
Suspension and General Condition
Press down on the front forks and rear to test smooth compression and rebound. Look at fork seals for oil streaks on the sliders; any leaking indicates service is needed. Inspect shock absorbers for sag, rust on the springs or leaking damping fluid.
Walk around the TX650 and check fasteners, exhaust mounts, and frame joints. Ensure footpegs and controls are securely attached, and that the seat latch holds the seat down firmly. A quick tug test on visible bolts helps avoid hardware failures midride.
Final Safety Check Before Riding
- Retract the kickstand and confirm the bike rests securely on both wheels.
- Adjust mirrors for full rearward visibility while seated in riding position.
- Put on proper protective gear and verify helmet chin strap and gloves fit correctly.
- Start the engine, listen for unusual noises, and roll forward a few feet to confirm braking, steering and clutch function under low speed.
Conclusion
Make the PreRide Checklist for a 1973 Yamaha TX650 Motorcycle a brief ritual before every outing. Regular, focused checks protect the bike's mechanical character and keep you in control on the road. A consistent routine turns these inspections into muscle memorysaving time and preventing problems so you can enjoy the ride with confidence.
