Hi,Garman...welcome aboard.
I can't tell you much about Detroit Choppers except that they're located near here...and I've checked out their little shop (nice enough) just for something to do.

Yeah...I know...they're not going to tell you what if anythings wrong with their machines. But if you have the V.I.N. for the bike (or good description) they ought to be able to fill you in at least on what you're looking at,etc...if they're still there,anyhow...not sure.
