Please read the description and study the photos as they form part of the description. This igniter was removed from my ZXR750R K1 which I have owned from new,the unit was removed after around 6 months as I fitted a race kit loom and higher limiter igniter,the unit was in perfect working order when last used and has been stored carefully in a clean and dry environment for several years and still has the original part number stamped on,however for various reasons I can not offer any guarantee on electrical components and also strongly recommend if you have a faulty igniter you first confirm there are no under lying issues with the bikes ignition system that may damage a replacement. Thankyou
