I hear you folks talking about seafoam all the time. Well, I got a can and added several ounces to my tank. I think I could tell the difference immediatly. The bike seemed to run smoother especially in cold weather. My question is, how often should you add it to your tank? I live in the south and ride 70 miles round trip to work almost every day. If I add seafoam every time I full up, thats going to be several cans a month. Anybody got any advice.
