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: 0.75 - 1.05 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: 9.8 - 12.8 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 #16V948000SUSPENSION:REAR

Received: 30/12/2016▼

Defect Description

BMW North America, LLC (BMW) is recalling certain model year 2016-2017 S 1000 RR motorcycles manufactured June 8, 2016, to November 16, 2016, and 2017 S 1000 R motorcycles manufactured on October 12, 2016. One of the bolts on the rear suspension deflection lever may loosen and adversely affect the handling of the motorcycle.

Safety Hazard / Consequence

If the bolt loosens and affects the motorcycle's handling, there may be an increased risk of a crash.

Factory Remedy & Repair Action

BMW will notify owners, and dealers will replace the bolts and tighten them to the proper specifications, free of charge. The recall began February 17, 2017. Owners may contact BMW customer service at 1-800-525-7417.

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.
