Brian,
That seems to be a New Mexico assigned number. I have seen many over the years. And as far as 2000 goes, any year when the production quantity gets up to that point has a 2 as the first digit. However your number is not H-d so irt is a moot point. Easy way to tell if it is a 165 is if it has provision for the carb covers, Hummers did not have the castings for them. The holes in the frame are for a coil mount, not a magneto which is part of the engine. Where are you located and where did the bike come from? The old dealer in Albuquerque used to assemble a lot of bikes from parts in the '60s and '70s. The bottom numbers on the cases will tell you what year they are.

A basket case Harley light weight was recently sold to me as a 1958 Hummer 165, in doing research mostly from this sight, I can't determine what year "Hummer" it is or if it is a 165. The engine serial is NM2001380. It seems that they started using the 2000 serial numbers in 1960. The frame appears to 58 or 59 as it has the reinforcements, the integral kick stand / footpeg, and magneto mount holes on the front downtube. "Hummer" is stamped on the top of the triple tree. The speedometer is either a 57 or 58, but the needle is missing so it is hard to differentiate which one it might be. Any help with the engine serial would be much appreciated and may help solve the mystery. Thanks. Brian
