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: 1.25 - 1.65 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: 11.5 - 14.8 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 #21V361000EXTERIOR LIGHTING:TURN SIGNAL

Received: 01/01/2021▼

Defect Description

Ducati North America (Ducati) is recalling certain 2021 Scrambler 800 Night Shift motorcycles. The front and rear turn signal lights may not flash brightly enough. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety Hazard / Consequence

Turn signal lights that aren't bright enough can reduce other driver's ability to see that the turn signals have been activated, increasing the risk of a crash.

Factory Remedy & Repair Action

Dealers will replace the front and rear turn signals, free of charge. Owner notification letters were mailed on June 28, 2021. Owners may contact Ducati customer service at 1-888-391-5446. Ducati's number for this recall is SRV-RCL-21-009.

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.
