Just to clarify things. I have a 1995 Ultra Classic with S&S carb. It has over 125,000 miles on it and i figure I should change or rebuild before I make any long trips. I've seen an engine from a 2008 fuel injected Ultra Classic used with low mileage. Can I use it for a swap and go back to carb.
Hey, welcome to the forum. No you can't, unless you want to do a lot of cutting, welding and then properly aligning it all... Cheaper to buy a new Bike.
I don't live far from you and can aide you in rebuilding if you like. I'm In Selden...
Anythings doable , question is will it be worth what it takes in the long run and how much extra has to changed along with the engine.
Not a drop in project for average garage guy.
True, but most motorcycle projects are not worth in dollar value, but to the owner its a labor of love. To shoe horn a 2008 twin cam into a EVO frame would be a cool project to someone with the time.
