Mike is a super talented mech/builder. As a guy who enjoys riding what I build only...this is one of, or maybe THE only guy in st.Louis that "I'd trust to get the thing moving the way it should. Or he may just tell you ..."it's time to think about a different powerhouse." that's a dude that could've been happy to let me spend a lot of money.... Once.
Because he's a solid dude that talks straight, I'll be a regular customer as long as I ride.
