Re: The Mile High says Hi!
Welcome to the forum. You've come to the right place for answers. I'm a 2 stroke guy myself but there are many 4 stroke builders here who will speak up soon and help you along. There's also a 4 stroke section devoted entirely to the 4 stroke bike.
Good luck and glad we have another Colorado builder among us.
