1953? Or 1966 modified twin spark plug twin carb hummer

Postby Bertstert973 » Fri Jun 21, 2019 1:58 pm

Hey guys I’m wondering what my bike is And also looking to see if there are any motor modifications that would be able to make the bike faster. I flat track and want to get this bike flying around the short track. Is there any aftermarket stuff for these bikes? And what about other motors that can fit within the frame. Obviously change motors mounts for them to fit
I can’t upload the pictures for some reason but the frame has a m with a square around it and says 47574-53 and the motor has 66bth0001 which is the 66 bth hummer. I would think it’s the first motor they made In production by the stamp? It has a twin spark plug head on it and a modified twin carb. Will post pictures when I figure out how to lol thanks guys

Not yet still have to adjust the carbs and throw a battery in it. It’s Definitely a cool bike and I’m curious to see how the power feels on this bike and if it would be good enough for the racing I do. Either way it’s one unique bike and I will have a lot of fun riding it around.

Isn't that a generator motor and not magneto like the BTH has?

It could be honestly I’m not to used to that bikes and motors. I’m trying to find out ways I can put more power into the bike for flat track racing. I even been looking at keeping it 100% Harley and put a sprint motor 250 or 250 into it. Just not sure how well it would all line up. Any one have the specs of the motor size and the frame sizes are for this model? Thanks. I kno a yz 125 motor has fit in a 50s hummer but not sure how it would work on this bike. I really would like to flat track race this and keep it 100% Harley. If I can keep the motor and get any parts for this motor to gain hp and overall power id appreciate any information. Kuz id like to keep it original and not swap motors but make it a fast ass original hummer

You can always do some extreme porting and get a good expansion chamber designed around your porting. There's a 50 125 that turned a 14.5 sec standing start 1/4 mile in 1950 on the Hummer club website
