I lost my AMB 260 transponder either at Summit Point directly after the last WERA race on Sept 19 or I lost it at Roger Lyle's MotorcycleXcitement track day at New Jersey Motorsports Park - Thunderbolt on Sept 22. It was just the actual transponder without the mount and charging accessories. The serial number is 3496690. I bought it new and it is registered to me. I know that no one can transfer it into another registered name without my consent, so I am hoping that someone finds it and gets in touch with me. My email is jeffarmy34 at yahoo.com Thanks in advance. :up:
