Check your own engine codes! Motorcycle Diagnostic Scanner OBD2 Adaptor 

I was very happy to have stumbled across these cool OBD 2 adaptor cords for motorcycles! I had no idea that they used the same standard OBD2 protocols that modern automobiles do. Use this conversion cable to plug a common ODB-II scanner into you bike to read and clear engine codes as well as view live data streams for vital engine information, very cool!
Here are a few links to adaptor cables. Definitely check to make sure that they will work for your specific bike but the list should get you pointed in the right direction.
