Hi Guys, I've been thinking about the possibility of changing the motor up in my Fatboy, I currently have a 1450 Fatboy 88cube, I think I'm right to take it to a 95 cube, but is it possible to take it to a 103?  and what else would need doing other than a rebore, cams?

103 you need to split the cases & put new crank in.
Another option is go straight to 98". What you spend on spliting cases with new crank you could just get your heads done up to a stg 2 or 3 & easily have over 100/100 with the right sticks to match

Do you know if I can go to 103, I was looking back after I posted on previous but not sure if I can.  We had a bit of a chat about it on the weekend, but differing opinions from different guys, me I'm farking hopeless with engines!!!

Cheers for that, I will talk to the boys.

Thanks, got the message finally!!! I'm on the darling downs anyone special I should talk to about doing this??
