Is it possible to put a Dyna engine in a rigid frame?
As the title says.... (if I in a far future want to build a rigid framed custom chopper)
Does it work with ANY rigid frame in that case?
It yes, why?
If no, why?

haha...so right....that´s why I ask....
But why arent more rigid chopper build on Dyna engines than...
Is it because of the balance axle in soft tails or the oil tank thing...

I wouldn't think there is a difference between "dyna" engine and "softail" engine from same era, mount-wise. I'm not all-knowing but thinking "would it be cost effective for Harley to have 3 different motors?" (Sporty, Dyna, Softail)
I mean, they have two...Sporty and Big Twin.

most rigid frames are designed for the twin cam B motor (softail) but there are a few companies that make rigid frames designed for the A motors in the dyna. I think Rolling Thunder makes em and possibly Paughco (not sure on that one though). I think the reason that the rigids are made for the B is, as you said the non-traditional location of the oil tank and the the fact the dyna motors have to be rubber mounted rather than solid mount like on the softails.....its just a much simpler set-up to use a softail motor but you can do it with your dyna - you just have less selection when choosing frames. Why don't you just cut up the existing frame and weld on a fabricated hardtail rear section like they did "back in the day"?

I'm learnin somethin today. I really thought the Twin cam A and B referenced eras not specific models. Like TC A was from 99-05...TC B is 06+.

well that seems to be how people have started to refer to them but originally the "B" stood for the softail motors because they have internal balancers and the "A" motors were the rubbermounted, non-balancer equipped ones in the Dynas and Baggers. Really quite different setups both in the mounting and in the location of the oiltanks.......not to mention the presence or lack of the internal balancers which were put in the rigid mounted B motors found in the softails to counter the vibration caused by virtue of their being bolted directly to the frame. This wasnt necessary on the dynas because of the rubber mounts......
