I've got about 4000 miles since I put my procom on . I'm happy life is good. The only thing I've learned to do (and not comdemen and try to find wrong with) is turn the key off and back on when I let it die when it is cold. I think it reset the procom and it starts right up with a littel choke. I've got my set on 6 with nothing unpluged. 132 jettes and it run's 85 MPH with a 16 tooth sprocket pushing a sidecar. Think I going to put 135 jettes in it and see what happens.rudyr
