• Fluids: confirm oil-injection level or pre-mix status and brake fluid condition.
• Controls & lights: throttle snaps back smoothly; clutch engages cleanly; all lights work.
• Suspension & visible leaks: check fork seals and shock for seepage.
• Final: kickstand up, mirrors set, helmet & gear on.

Tires and Wheels

The 1974 Yamaha RD350 is a street-focused machine with narrow front and rear profiles by modern standards. Start by pressing each tire with the pad of your thumb to sense pressure and then scan the tread for flat spots, embedded debris, or abnormal wear patterns. Because the RD350's handling is so responsive, even small pressure changes noticeably affect cornering.

Look closely at the sidewalls for cracking from age. Given the bike's era, many RD350s run older tires on classic rims; any signs of dry rot or bulges mean replacement before a spirited ride. Spin each wheel while holding the forks or swingarm to detect wobbles, loose spokes, or rim damage that would upset the bike at speed.

Brakes

Braking performance on a classic RD350 demands your attention. Squeeze the front lever and apply the rear pedal; both should offer progressive resistance rather than a spongy feel. If either lever bottoms out easily, inspect for air in the system or worn friction material. The front brake on many RD350s is a single-disc setupcheck pad thickness and look for uneven wear or glazing on the disc surface.

Confirm the brake light activates when pressure is applied. A reliable stop is the single most important safety feature on a vintage bike with lively acceleration like the RD350.

Chain / Drivetrain

The RD350 uses a conventional roller chain. With the motorcycle on its sidestand or a paddock stand, check chain tension at the swingarm midpoint. The chain should have a little vertical play but not be slack enough to skip teeth. Tighten using the rear axle adjusters if needed, making sure the wheel remains aligned.

After adjusting, wipe excess grime with a rag and apply a quality chain lube to rollers and linksfocus on the area that contacts the sprockets. Inspect sprocket teeth for hooked or chopped shapes; replace any suspect sprockets along with the chain to maintain smooth power delivery.

Fluids

On a two-stroke 1974 Yamaha RD350, check the oil-injection tank if equipped, or verify your pre-mix ratio if the bike is set up that way. Low oil or incorrect mixing leads to seized pistons quickly on a two-stroke engine. Smell the exhaust and listen for irregular smoke patterns that could hint at lubrication issues.

Inspect brake fluid reservoirs for level and color; dark, cloudy fluid indicates replacement is due. The RD350 does not require coolant, but if a custom cooling setup exists on your example, confirm levels and hoses. Top off visible fluids only as needed and record when each was last changed to build a maintenance habit.

Controls and Lights

Twist the throttle and release it to confirm a smooth returnno sticking or hanging. The characteristic snappy throttle of the RD350 must return cleanly to avoid unintended acceleration. Test the clutch lever for free play and smooth engagement; cables can stretch or fray, especially on older machines.

Cycle the headlight high & low beams, turn signals, and horn. Replace any bulbs that fail and ensure connectors are secure. For night or low-light rides, make sure the headlight aim is correct to prevent poor illumination or dazzling other drivers.

Suspension and General Condition

Press down on the front forks and rear shock to check for smooth travel and rebound. Observe fork seals for oil weeping and the rear shock for dampness or collapsed springs. These symptoms reduce control and should be addressed before aggressive riding.

Walk around the bike to look for loose fasteners, cracked mounts, or missing guards. The frame, footpegs, and switch housings should be secure; early rattles can indicate worn components that worsen on the road.

Final Safety Check Before Riding

• Kickstand: ensure it retracts fully and that the bike won't drop when leaned.
• Mirrors: adjust for rearward visibility; tighten any loose mounts.
• Gear readiness: helmet strapped, gloves on, jacket closed, and boots fitted.
• Quick walkaround: listen for loose parts and confirm no fuel odor or leaks.

Conclusion

Consistent, focused inspections keep your 1974 Yamaha RD350 Motorcycle reliable and enjoyable. Make this checklist a short ritual before every journeyyour vintage twin responds to care, and small checks prevent big problems. Habitual attention preserves both the bike's performance and the thrill of riding it.
