    I have Thor single K.1461. I thought it to be 1908.

    What I thought to be an '08 model is in fact I believe to be a 1911 model K. When Thor stopped supplying Indian motors in 1910 and Indian started making their own motors the Thor upper end went to a beehive style cylinder instead of the four long bolt tall cylinder style. Mine is stamped with a K before it's four numbers and has the updated barrel. I know this barrel was made for the Minneapolis in 1910 by Thor but didn't show up on a Thor bike till 1911 as the model K. Check Steve Wright's book. I hope this makes since.

    I believe a little after 1911 I'm not exactly sure when but they didn't rivet a metal plate with the serial numbers instead they were stamped on the case and the exhaust moved forward on the upper end. Someone now for sure?
