I'm converting my car to F600 (07 gsxr 600 mc engine) and need to resurrect my lambda sensor in the AiM data logger. Can someone confirm the weld in bung is 18M x 1.5 thread? Also, it used a four (4) wire Bosch LSM-11 sensor. Is there a replacement (updated sensor) available? May need a new one if the old one (LSM-11) should prove to be bad? And hopefully the replacement will be cheaper! Thanks. Ted
