if its an early speedfight pre-2001 it may have been bypassed, i can do this, or even tell you how to (nominal fee) (priveledged information) easy way to tell is that it should have the 2 box setup on it, cdi by the battery 2 multi connectors with 4 wires and immobilizer unit behind ignition panel, anyway, there is no way that bike would run without the chip in the key if it had an immobilizer, no way unless it has been bypassed. i have a non immobilizer unit for sale brand new, so if you need it get in touch, couple of people on here are after it, and better still its 100 all in inc p+p
