Quick 60-Second Pre-Ride Checklist for the motorcycle listed in PreRide Checklist for a 1981 Suzuki GS650G Motorcycle

  • Ignition on – confirm dash lights and neutral indicator illuminate.
  • Front and rear brake lever/pedal – firm feel, no dragging.
  • Tires & wheels – correct inflation, no bulges or cuts.
  • Chain tension & lubrication – correct slack and a light lubricant film.
  • Lights & signals – headlight high/low, brake light, turn signals functional.
  • Throttle & clutch freeplay – smooth return and expected slack.
  • Mirrors, kickstand, and gear engagement – adjusted and secure.

Tires and Wheels

The 1981 Suzuki GS650G is a street-oriented machine; tire condition directly affects its predictable handling. Check pressure cold to the PSI you normally run for this bike and adjust before riding. Inspect the tread for even wear across the contact patch and look for embedded objects, sidewall cracking, or flat spots from long sits.

Spin each wheel if possible and watch for wobble or rim damage. The GS650G's wheel bearings should feel smooth; any roughness or play in the hub warrants addressing before hitting the road.

Brakes

Braking is the single most critical system. On your PreRide Checklist for a 1981 Suzuki GS650G Motorcycle, test the front lever and rear pedal for firm, progressive engagement. The front master cylinder should not feel spongy; squeeze several times to confirm consistent pressure.

Visually inspect the pads (or shoes) through caliper openings for remaining material. Check the brake fluid reservoir level and that fluid is clean rather than dark. Apply the brakes while rolling slowly to ensure the rear is not dragging and the front stops cleanly without grabbing or noise.

Chain / Drivetrain

The GS650G uses a chain-driven final drive. Start by placing the bike on its centerstand or paddock stand and measure chain slack at the midpoint of the lower run. Look for tight spots, excessive slack, or stiff links. Adjust tension so it falls within the range you normally use for this model, and align the rear wheel using the axle marks.

Lubricate the chain with a light, penetrating chain lube, concentrating on the inner links and rollers. While you're at it, inspect sprocket teeth for hooked, chipped, or uneven wear. Replace worn sprockets before the chain fails. Check the sprocket nuts and chain adjuster nuts for tightness.

Fluids

Fluid checks are quick and impactful. Verify engine oil level on the dipstick; the GS650G prefers a visible, proper oil height and reasonably clean oil. Top up if low, and note any rapid drop between rides.

Although this model is air-cooled, still verify there are no oil leaks around seals or the engine casing. Inspect brake fluid reservoirs for level and clarity. If the bike has been stored cold, warm it briefly to circulate oil and make readings more accurate.

Controls and Lights

Operate the throttle and ensure it snaps back smoothly when released. Test clutch lever freeplay and ease of engagement; the GS650G's cable-actuated clutch should move without binding. Wiggle cables to ensure ends and adjusters are secure.

Turn on the headlight, test both high and low beams, and confirm taillight and brake light illuminate when the brake lever/pedal is applied. Cycle the left and right turn signals and listen for a steady cadence; uneven blinking can indicate a bulb or grounding problem. Adjust mirror positions so you have an unobstructed rear view for this bike's riding stance.

Suspension and General Condition

Feel for fork seal leaks by pressing down on the front end and scanning the fork tubes for seepage. The GS650G's front forks should compress smoothly without harshness or sudden clunks. Check rear shock for sag, oil stains, or loose mounting hardware.

Walk around the motorcycle and look for loose fasteners, missing caps, cracked plastics, or any fluid weeps. Ensure the battery is secured and terminals are clean; a loose battery can lead to intermittent electrics on older bikes like the GS650G.

Final Safety Check Before Riding

  • Confirm the kickstand retracts fully and the safety switch (if fitted) operates when up.
  • Verify gear engagement by shifting through gears while the engine is stopped or at idle to ensure the transmission selects cleanly.
  • Adjust mirrors for a clear rearward view, fasten helmet and protective gear, and secure any cargo.
  • Perform a slow roll and re-check brakes & steering feel before accelerating into traffic.

Conclusion

Consistent checks keep your PreRide Checklist for a 1981 Suzuki GS650G Motorcycle quick and effective. A short, methodical routine prevents small faults from becoming roadside failures. Make these inspections a habit each time you prepare to ride, and your GS650G will reward you with reliability and predictable handling.
