Well, I'm not positive that I do. The bike had a seemingly random problem with stuttering at speed and stalling at idle for years. I replaced the the TPS on the suggestion of a friend several years ago and that solved the problem. Now the problem is back, and after my last REALLY rough ride home it won't even run for more than 5 seconds without stalling. I know the Rocket has chronic probs with that so I was hoping it would do the trick. I cleaned the MAP sensor, checked the wires and plugs and prayed a lot. Still can't seem to get in the epic autumn ride I was looking forward to.
