Engine swap

[davidson]

  Hey i'm a new guy with a question. Just bought a basket case
1976 125 GS at the Barbers vintage race and swap meet.I'm
restoring it and was wondering if i could find a 175 top end and
would it fit my 125 case's? Mine is the KTM motor and not the Sach's.
 If anyone knows if this was possible I would appreciate the information.
             Thanks James

No a 175 topend will not fit in stock form. You will have to do some triming on the cases to let it except a 175 cylinder. Hope this will help Gary

  Thanks for the information, I'll probably go back stock.
