Models: BMW R Model Motorcycle Year: 2003
Number Potentially Involved: 7,000
Dates of Manufacture: December 2002 – August 2003
Defect: On certain motorcycles (Opposed Twins w/Two-Spark Ignition), the electrical wiring for the oxygen sensor and the ignition lead for the right-hand secondary spark plug have a parallel routing over part of their installation path. The close proximity of these cables may allow the signal from the ignition lead to interfere with the signal from the oxygen sensor wiring. As a result, engine hesitation or misfiring could occur, which could result in a crash.
Remedy: Dealers will re-route the electrical wiring to the oxygen sensor. The manufacturer has reported that owner notification is expected to begin during December 2003. Owners may contact BMW at 1-800-831-1117, Option #4.
