Six Days.......250 engine?

[Cathump]

I probably know the answer to this, but here goes. Has anyone tried putting a 250 engine in a '74 Six Days frame?

I love my bike, but a 125 just isn't doing it. I am a big boy and need more bottom end.

Use a 72-73 jackpiner frame or a 76 125 frame it will bolt right in. Im building one with a 76 frame, same as the jackpiner frame but takes the long seat and the conical r wheel. Im going to put a Carl Cranke ported 250 in it and probebly kill myself...but what a way to go!
