Default engine upgrades

I have a 2006 fat boy screaming eagle with the 103B engine. Thinking of re-powering due to mileage and was wondering if anyone knows whether a 2007 model 110B engine will bolt in without modifying.

Thanks.

I wouldn't put forth the effort for the return. You'd be better off bang-for-buck-wise with a 107 kit from FM, Zippers, Hillside. JMHO.. With a 110, if that model year was TBW then you'd need the accompanying electronics / ecm.

^---- What he said. I wish I lived further east because I'd kill for Fuel Moto to install a 107 kit on my bike.

Retmar- BTW, your 2006 FB is fortunately geared very well for speed as this was right before the 2007-up "epa friendly" overly tall belt drive pulleys were introduced. so again IMO, build up your current motor (107" is a damn good Ci), cam it, go larger on the TB (50-53mm) and injectors (4.9), and tear it up with a reliable street performance motor for less cost / hassle.
