Suzuki GSXR125 Dealer Mode How to. F1 FI Code Diagnostic Mode

A short how to video showing how you get your Suzuki GSXR125 in to Dealer Mode for fault code diagnosis. Fault codes below...

(Update: a couple of small squirts of WD40 in the ignition barrel; after a few hours the FI code disappeared)
