I just bought a set of pistons out of a 103" screamin eagle fat boy.&nbsp\\; Is there any reasons they wouldn't fit in my 07 flht to make it a 103"?

 

The 96" motor can be punched to 103", SAME as a 88" to a 95".. same barrels too..Steve

 

Just rebore your cylinders or buy a set of big bore jugs from harley and you will have your 103.

 

depends on what year the 103 pistons are.&nbsp\\; If they are from a year prior to 06 dyna or&nbsp\\;07 bagger they will not work as the cranks are different.&nbsp\\; If they are 103's from an 07 bagger disregard above statement.

&nbsp\\; 2 reasons!&nbsp\\; &nbsp\\; 1 is juggs,&nbsp\\; 2 is heads,&nbsp\\;&nbsp\\;Your &nbsp\\;jugs can be rebored to the size of your pistons or you can buy&nbsp\\;SE jugs
part number 16546-99 black or 16549-99 silver. Your stock 07&nbsp\\;heads&nbsp\\; are for flat top pistons, so in order to use the 103 cvo pistons you eather need to use SE&nbsp\\;103 cvo heads parts numbers 16900-03a "front" and16977-03a "rear" at $600.00 ea,
or SE 103+ heads part number 17071-03b black&nbsp\\;$1,149.95 or 17072-03b silver $1,099.95&nbsp\\; I am hoping you all the luck in the world

 

Yes they will work fine
