THERE SEEMS TO BE SOME CONFUSION ON THE INTERNET THAT THIS POSSIBLY FITS A YAMAHA IT 250 ,  IT DOES NOT.

HOW CAN A 400 PISTON FIT A 250?  IT IS BECAUSE SOME OF THE MICRO FICHE  FROM THE 70S AND 80S SHOWED 2 BIKES ON ONE FICHE. WHEN IT WAS TRANSFERRED TO THE INTERNET IT WAS NOT BROKEN DOWN. 250 PISTONS START WITH 1W5.  PLEASE CHECK YOU NUMBERS OR MESSAGE ME FOR THE CORRECT INFORMATION.
