Hey I just used some Sea Foam in the engine recently. I can't offer anything special, but my own personal results. I added about a 1/4 of the can, directly into the crankcase. I drove my ride at moderate speeds for about 2 miles in my neighborhood, then returned home. I then changed the oil, using Castrol 10w-30 synthetic blend oil. My motor sounded quieter, and also felt like a little bit of power/performance was regained. HTH <img src="/forums/images/graemlins/smile.gif" alt="" />
