I have not had any problems with any injectors i have come across on the YBR 125  , i did once wire one up incorrectly which gave an injector fault but that was my fault .

i have even had customers buy injectors from me after questioning and they were convinced the injector was at fault only for them to bring it back a few days later .

Do yourself and the person your buying parts from a favour and test the components  , all the tests you need to do are in the Yamaha YBR 125 Haynes manual so buy one and save money , do not just randomly buy components hoping to guess correctly it rarely works  .

you can easily hear the injector firing when the engine is running , or you can check the fault codes -
see out injector fault codes post here .

you can also use the Yamaha FI fuel injection diagnostics machine , which simulates 5 x fires of the
injector to test them , if you have access to one its and excellent tool to own . see our Yamaha FI diagnostics post here .

I have not seen an actual figure for this but i have got 3 x functioning Yamaha YBR 125 Injectors here

easy to do set Multi meter to ohms ( auto ) and test between both terminals
