I have an 03 1100 Custom which I really enjoy but lately have had issues with backfiring. I took off the surge tank to check to see if all hoses were connected and all were in good shape. However, I did notices that the "horseshoe" shaped device on the left side seemed to have a slack in the "back" cable. When throttling up, the "front" cable is tight and fits nicely in the groove of the "horseshoe" device and the return spring seems to work well. However, the back cable seems to have about 1/8 to 1/4" slack in it. There is a horizontal "peg" that holds the cable in place. Is there a way to take out the slack? I have a feeling that this possibly may be contributing to my backfiring issue because it may not be "cleanly" releasing when I let off the throttle. Any and all advice will be greatly appreciated.
