We are currently recommending the use of Indian Motorcycle’s Stage 2 ECM Reflash to replace the use of our Stumblefocker valve for 585 cammed applications. The Stage 2 download offers the same benefit, without the need for our mechanical valve.
Contact Indian Motorcycle Charlotte, or your local Indian Motorcycle dealer, to have your ECM reflashed with Indian Motorcycle’s Stage 2 Download.
This item is intended for use on Thunder Stroke 111″ model Indian Motorcycles, in conjunction with our 585 cam profile. This valve will help alleviate an idle-stumble condition that may occur after the installation of our 585 cams, due to the aggressive lift of the cam.
