I have a 2011 Husaberg FE570. I believe that the injector is a Keihin.
The bike isn't starting well and I know that the FI system is overdue new filters and cleaning of the injector.
However, the injector has been upgraded by KTM and I'm debating whether to get my current injector cleaned or buy the new upgraded item. If anyone were to say that cleaning is not very effective, then I'd buy a new one.
