FACTORY SPECIFICATION
Metallurgy & Center Tip Architecture
Copper Core / Solid Nickel Alloy Ground Electrode
Thermal Dissipation Path & Physics
Standard OEM factory thermal dissipation rate. Calibrated to stabilize ceramic nose temperature between 500°C–800°C across mixed street, highway, and mountain riding.
Operating Application Envelope
Stock engines, factory ECU mapping, general commuting, and standard touring. Recommended for all baseline maintenance schedules.
Ignitability & Coil Voltage Demand
Standard spark kernel size. Standard secondary coil demand (~15–20 kV). Solid copper core ensures rapid heat conduction away from tip.
SPARK PLUG READING & COMBUSTION DIAGNOSTICS ANALYZER
Interactive visual diagnosis: Match your ceramic insulator tip and electrodes to detect AFR, timing, oil intrusion, and thermal overload
Normal Clean — Optimal Combustion Equilibrium
OPTIMAL COMBUSTION
Thermal Operating Range: 500°C – 800°C (932°F – 1,472°F) • Self-Cleaning Pyrolysis Window
Visual Insulator & Electrode Profile
Ceramic insulator nose is light grayish-tan, beige, or light brown. Firing tip and electrodes are dry with minimal combustion deposits. Ground electrode edges remain crisp without rounding or erosion.
Multimeter Electrical Resistance Test
Insulation Resistance > 10 MΩ (Infinite DC resistance between center terminal and steel shell). Dielectric barrier is pristine; zero spark leakage to cylinder head ground.
Probable Root Causes
  • Optimal air/fuel ratio across all throttle positions (stoichiometric 14.7:1 cruise, 12.8:1–13.2:1 power enrichment)
  • Correct spark plug heat range precisely matched to engine displacement and cooling efficiency
  • Ignition timing and coil dwell saturation within factory parameters
  • Healthy piston rings and valve guide seals with minimal oil blow-by
Prescribed Workshop Remediation Action
No mechanical intervention required. Inspect gap with wire-style feeler gauge and reinstall to factory torque specification.
Coil-on-Plug (COP) / Stick Coil Multimeter Bench Testing Protocol
Step 1 • Primary Circuit
Set DMM to lowest Ω range. Probe between Terminal 1 (+12V switched) and Terminal 2 (ECU trigger pin). Normal reading: 1.10 - 1.40 Ω at 20°C at 20°C.
Step 2 • Secondary Circuit
Set DMM to kΩ range. Probe between Terminal 1 and the high-voltage spark plug spring terminal inside the boot. Factory spec: 8.5 - 11.5 kΩ at 20°C at 20°C.
Step 3 • Dielectric Boot Inspection
Flex silicone boot under bright light. Check for pinholes, white powdery dielectric breakdown tracks, or hardened silicone causing high-voltage flashover to the cylinder head spark plug tube.

NHTSA #18V694000FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP
Received: 04/10/2018▼
Defect Description

Suzuki Motor of America, Inc. (Suzuki) is recalling certain 2017-2018 Suzuki DL650A, DL650XA, GSX-R1000, GSX-R1000R, and 2018 GSX-S750 motorcycles. During installation, the fuel pump O-ring may have been twisted, reducing the sealing performance and possibly resulting in a fuel leak.

Safety Hazard / Consequence

A fuel leak in the presence of an ignition source can increase the risk of a fire.

Factory Remedy & Repair Action

Suzuki will notify owners, and dealers will replace the fuel pump O-ring and the fuel tank inner vessel, free of charge. The recall began October 31, 2018. Owners may contact Suzuki customer service at 1-800-934-0934. Suzuki's numbers for this recall are 2A86-2A88.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
