Well, I had a great friend sell me a very special engine. These engines are VERY hard to find. It is a 25cc yankee F7 "Tuned" engine. The engine has a carbon fiber reed box, billit aluminum crank case and is ported and polished. These engines retailed for over $900 and were so elite that they came in a custom wood box with a serial number on them. I sure cant wait to get it!!! Sweeeeeeeeet!!
