Yamaha FI diagnostics machine , it just arrived this mourning , only had it 2 hours and not used it to its full extent but ran through a few live tests .
and its excellent i have to admit its probably not needed as most of the tests can be done without it
but wheres the fun in that !!

for the price i cannot fault it ! .



the manual is not very clear on how to connect and use this so it was a bit trial and error .


How to connect the FI diagnostics to Yamaha YBR 125


this is how i did it anyway correct me if i make any mistakes in comments 

-first turn key to off positon 

-disconnect the fuel injection pump wiring connector block 


-remove side panel and split the light green Ecu-Diagnostics connector block
-connect yamaha FI unit to wire and the battery leads to + and - terminals 
-press and hold mode button down 
-turn key to on position
-display on Yamaha FI unit should now read Diag .

    1. part of testing is - sparking ingition coil and firing the injector , so it might be so bike does not fire up and run during testing .
