I have 88" twin can b model motor for a 2001 FatBoy and am wanting to know it I can bore the jugs out to a 97" and just buy new Pistons for the bike? Has anyone ever done this or know if it's possible
3.937 is as big as you can go. This yields the 98."
Kirby, above, or Scott at Hillside are the guys to talk to. Got mine from Hillside. Love every "inch" of it.
we use either wiseco or CP.you can get the pistons from either.just make sure who ever is doing the boring has the right equipment & knowledge.having the cylinder perfectly centered & straight is VERY important when doing the 3.937" bores
