Effects of incorrect gap: misfires, weak spark, and premature wear. 2. Tools & Prep Tools required: feeler gauges, dial indicator, timing light, test light or buzzer, small file, contact cleaner, lubricant. Pre-cleaning: file and clean contacts, replace condenser if weak, clean with non-residual spray. 3. Static Setup (Bench Setting) Open points fully before measuring. Adjust using a feeler gauge to 0.3 mm. Ensure both cylinders are matched equally. 4. Dynamic Timing & Spark Gap Find TDC using a dial indicator, then rotate back to about 2.0 mm BTDC. Spark should occur right at this position. Both cylinders must match within ±0.2 mm. 5. Verification Use a test light or buzzer to confirm the exact moment of point opening. Check with a timing light while the engine is running to confirm accuracy. 6. Upgrades & Maintenance Tips For improved spark and less maintenance, consider a CDI conversion with a points interface. Regular checks: clean contacts, keep gap correct, match both cylinders, and check coils. 7. Troubleshooting If no spark: clean points, check condenser, test coils, and ensure gap/timing isn’t off. Replace worn contacts or weak condenser if needed. #YamahaRD350 #RD350 #BreakerPoints #IgnitionTiming #TwoStroke #MotorcycleRestoration #DIYMotorcycle #TimingSetup
