How wide is a cag motor ( pocketbike motor )?

How wide is a cag ( pocketbike motor ) motor, it would be even more helpful to know how wide a cag motor is with a 3:1 reduction transfer box (as found on the mini dirt bikes) on it?

I just measured my pb engine from bellhousing face to pullstart housing face.

It is exactly 7" wide.

Thank you, just working out whether it is feasable to have a bottom bracket made up so that it is wide enough for the cranks to clear the motor, the widest standard one i can find is a profile one at 6 7/8".
