Title: 74 250 Maico barrel on a 77
Post by: Jumbo J on June 08, 2016, 07:11:43 pm

does anyone here know if a 74 AW250 barrel will bolt straight onto a 77 AW400 crankcase and convert it to a 250 without modification?

The 400 has a different stroke so a 250 crank would be needed. From memory the stud pattern should be the same for those years.
