Well folks, I am genuinely chuff, got my bike back from KTM Durban last week, did +- 230 kms running around without any issues.
Then did a ride of 450kms on Saturday of all you types of terrain on dirt.
My bike went like a steam train, best power and throttle response I have ever experienced.
Thanks must go to Wayne & his team at KTM Durban for all his patience and perceiverance in sorting the issue out.
Turns out that we found a link on advertising riders, ktm 690 endure forum, they spoke about an adjustable screw in the throttle body hidden behind a riveted plate!!
Did the mod adjusted the screw half a turn and voila!!
Once again thanks Wayne you are a legend!!!
