Fuel Delivery, Throttle Body Synchronization & Manometer Balancer

Factory intake depression specifications (250 mmHg), electronic fuel pump pressure testing (51 PSI), injector resistance, and interactive multi-column manometer balancing.

Warm Idle: 1,050 - 1,150 RPM

Quick Workshop Diagnostic Presets

Simulate Throttle Linkage Asymmetry, Hunting Idle, or Intake Boot Vacuum Leaks

OPTIMAL SYNCHRONIZATION: BALANCED (Δ ≤ 15 mmHg)

Diagnostics:Max Differential: Δ 0 mmHg (Factory Max Tolerance: ≤ 15 mmHg)

All 2 throttle plates pull uniform intake depression within factory engineering tolerance (≤ 15 mmHg / 2.00 kPa). Delivers immediate linear throttle pickup, silky smooth idle, uniform cylinder torque pulses, and balanced exhaust temperatures.

Workshop Multi-Column Fluid Manometer

Damped intake depression columns. Target spec: 250 mmHg (±15 mmHg) at warm idle (1,050 - 1,150 RPM).

Reference: Left Cylinder (Throttle Body #1)

Mechanism: Bypass Screws

Fuel Injector Resistance & Induction Specs

Multimeter Bench Check

OEM Injector Solenoid Resistance

12.0 - 12.5 Ω at 20°C

Measure across injector 2-pin harness socket with ignition OFF. Internal coil resistance increases by ~0.4% per °C rise above 20°C (68°F). Replace injector if resistance reads open (> 100 kΩ) or shorted (< 2 Ω).

Induction Type

BMS-O Electronic Engine Management with Ride-by-Wire & ShiftCam VVT

Injector O-rings must be lubricated with a light coat of clean engine oil before seating into fuel rail.

0 of 4 Steps Complete

1CLICK TO MARK DONE

Engine Pre-Flight Conditioning

Check and adjust valve clearances to spec before attempting sync. Ensure air filter is clean, spark plugs are fresh, and engine is fully warmed to operating temperature (80°C–90°C).

2CLICK TO MARK DONE

Manometer Connection & Damping

Connect 2-column liquid or digital manometer hoses to Under-throttle body vacuum test ports sealed with M6 grub screws and O-rings. Adjust in-line hose restrictor valves to dampen rapid intake pulsation until fluid columns stabilize.

3CLICK TO MARK DONE

Balance Screw Calibration

With engine idling at 1,050 - 1,150 RPM, identify Left Cylinder (Throttle Body #1). Adjust BMS-O ECU calibrated stepper motor idle actuators (Sync Bowden cables at 2,500 RPM) until all cylinder columns are within 15 mmHg (2.00 kPa) of the master reference.

4CLICK TO MARK DONE

Throttle Blip & Locknut Verification

Blip throttle to 3,000 RPM 2–3 times and verify columns return evenly to idle balance. Tighten any balance screw locknuts securely, re-install rubber vacuum sealing caps, and verify idle speed.

NHTSA #14V211000POWER TRAIN:MANUAL TRANSMISSION

Received: 18/04/2014▼

Defect Description

BMW of North America, LLC (BMW) is recalling certain model year 2013 R 1200 GS motorcycles manufactured November 2012 through August 2013. Pressure inside the transmission may cause the transmission output seal to be pushed out of place.

Safety Hazard / Consequence

If the output seal ring is pushed out of its proper position, oil may leak from the transmission onto the rear tire, increasing the risk of a crash.

Factory Remedy & Repair Action

BMW will notify owners, and dealers will fit a bracket to prevent the transmission seal from being pushed out of position, free of charge. The recall began on June 17, 2014. 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.
