ec121: Your reply/post is right on the mark. Some of the other guys get on here and try and tell the rest of us what we will enjoy. Hey some of us enjoy helping others any way we can...and most of us cannot afford to crash a real expensive engine. Now as to the Guy who said air cooled motorcycle engines are on the way out. On the smaller cc engines there will always be air cooled motorcycle engines. You can take that to the bank. You will probably see tunned exhaust made super light with carbon-fiber technology. Also smaller like the magic muffler. The reason is simply why.....we all want it to happen. Some person who is not even a engineer may help develop those very same ideas. Keep up the good ideas coming.....its good for us all. Captinjohn
