I believe issued on 23rd Feb. Would someone be good enough to tell me what the issue is with the alternator rotor machining? Can't find any info on this in the UK. | ||

This looks messy but you get the drift Reason For Revision The purpose of this revision is to correctly identify the calibration update part numbers. Refer to Table 1. Purpose Incomplete machining of the teeth on the alternator rotor may lead to a synchronous error with the crank position sensor (CKP) that can cause drivability issues. A new calibration has recently been implemented on the production line which provides diagnostic capability to identify sync errors (DTC P0339) caused by incompletely machined rotor teeth. The new calibration also provides continued drivability improvements. Motorcycles Affected 2009 Buell 1125R and 1125CR models built through January 12, 2009. Required Dealer Action If there is a drivability issue with a 2009 Buell 1125 model, follow these steps: 1. Identify the calibration in the ECM. If it is not the latest calibration, recalibrate the ECM. Refer to Table 1. 2. Test ride the motorcycle. 3. Read the diagnostic trouble codes: a. No Codes: Follow “Tips for Diagnosing Buell 1125 Drivability Issues” September 18, 2008 tech tip. Refer to TT390 on www.h-dnet.com. b. Code P0339 CKP Intermittent Circuit: Inspect the alternator rotor CKP trigger gap. 4. Remove the ignition cover and turn the crankshaft nut until the CKP trigger gap in the alternator rotor teeth is visible: a. Complete Machining: See Figure 1. If the CKP trigger gap is completely machined, follow the DTC P0339 diagnostic flow chart. Refer to the electrical diagnostic manual. b. Incomplete Machining: See Figure 2. If the CKP trigger gap is incompletely machined, replace the rotor. Follow normal warranty claim procedures for rotor replacement. | ||

Wow, I should send this to the dealers that tried to fix my bike a while ago. |
