A question that I'm sure you'll find the answer to here. :idea:

Does an F1B fuel tank fit in a 1990 750 Sport frame?
I know the frame is directly derived from F1, but I think the top part had to be resized for the Weber air filter box and the battery.
Removing that obstacle, I don't know how it would fit... has anyone made this modification?

No way. The F1 tank is a long triangle at the base, and the Sport is round like a turtle. The frames have similar lines. The Sport tank is closer to a 1990s 900 SS. MikeV

The experience of life, made up of trial and error, is as if you were to ask me... falling to the ground on asphalt... is it pleasant?
I answer you with certainty.
NO! :lol:
