This frame weighs only 5lbs.

I bought this frame today was surprised at how light weight and well built this frame is. I'm not sure who makes this frame because previous owner got this in a storage locker he bought at auction. Paid only $50. Going to use this frame on a new build.

Here is another picture. I'm using this motor just for mock up. Looks like there will be enough room for a slant spark plug head. Plenty of room for carb or Reed valve set up too.
