Hello fellow riders,

I diganosed the FI light on LCD scrren to be a c28 dealer code which indicated a fault in STVA (Secondary Throttle Valve Actuator) system.

What i have done since then:

1. Cleaned my throttle body and STVA flaps properly. { No fix :-( }
2. Searched the internet, suggests soldering job on the joints to fix that but concern is mainly that the forums mentions gsxr 600 / 750 extensively everywhere so will that work in my gsxr1000 2011.

How do i proceed with the fix and what can be the cause ,Need help from people with experience that can guide in perfect path.

Image 1 : c28 code and Image 2 : throttle body cleaning work.
Thanks
