Bagger - twin cam
Everything else - evo (due to my never owning a pan or shover, etc.)
I have had several evo's and loved them and love is an understatement but the way the twinkie runs makes it the perfect bagger motor. I will always be loyal to an evo with a carb and no baffles...
I am planning another build however and am comtemplating the 103" pan as I never had a pan and need one...
hey Dave - you related to Jabba or pizza?

Twinkie:
- probably better head design with a little tweaking.
- early cam bearing problems.
- lower end has shown some weaknesses with the flywheels scissoring on some engines, and main bearing set-ups some consider "throw-away".
- cam tensioners will always be a weak point, requiring expensive maintenance, or distrastrous results.
Evo:
- some years had porous cases.
- later models had what some call "throw-away" main bearing setups.
- lifters have been troublesome.
Solution:
- most don't keep their bikes long enough to need a solution.
- Evo engines seem to lend themselves to easier modifications, with more "user-friendly" options available, making them more popular with the aftermarket bike-building crowd.

Imho the late Evo's are better than the first ones. They made small changes over time. The cylinder base gaskets come to mind.
I'm partial to the evo with a carb just because it's so basic. I think it sounds better too. Flame away, but I believe a stage one evo will outrun a stage one 88 twinkie. It could be different gearing or something I don't know about, but that's my experience.
My injected TC88 defininitely starts easier and runs smoother when cold than the carbed evos, but that's no biggie because the evo's aren't really a problem.
I don't even want to know what it would cost to replace the electronics on the fuel injection unit if it pukes. Right about then I'll be wishing for a carb on the Deuce, I'll bet.
I do know that the evo's are proven and long lived. By the way, the article said that the engine on the million mile bike had been rebuilt - about 250k miles between rebuilds or something?
$.02

Got a 85 Tour glide ( the butt ugly ancestor to those good looking road glides, the fixed fairing bikes) and it runs strong and its stock. Quick and quiet! only trouble has been weak charging system. Updated that. 07 springer classic, nice bike, idles higher, love the extra gear! miss the fuel petcock and the choke and sometimes she makes a hell of a noise at start! Rush slipons way cool ride! Better? Time will tell.
