needing help finding the correct engine for my 2006 screaming eagle ultra. Will all 103A model motors fit? or are there different sizes and types of frames? If so what years will work with my bike?

 

If it is a 6 speed then yes. Any TC from an 06 Dyna TC 88 and TC 96 on to a 120 will bolt to a six speed. If it is a 5 speed then there is a limit of HD engines but not S&S or some other makes.

 

what he said. 06 down is a different mounting process for oil lines, more than likely your bike came stock with a 5 speed . or go S&S

i would go S&S 124.

 

Yeah, I would go with the S&S.

 

thanks everyone!
