There's loads of companies out there that make reproductions of Knucks, Pans, Shovels & Evos, but I'm looking for a new, modern version (using modern technology) flathead motor, preferrbly an 80 / 88 incher. I know Kiwi has new motors but let's see some harleys out there! Something that'll mate to a 5 / 6 speed primary that'll let 'em keep up with freeway speeds...and being flatheads, they'd last forever!

 

I'm building a 40' flathead 80, will go in a 74 superglide frame, with a 90's 5 speed tranny from a softail. The thing fits like a glove a Sportster real belt sprocket will accept a belt to the tranny and I will run a primary belt drive. That way I can turn off the chain oiler "on all those models" and get rid of the oil leak. Did not modify the frame in any way, even leaving the rear shocks. Using a 45 ci springer, and had to lower the rear end 2 inches. Using early model fenders and the superflide frame accepts a seat post for a harley solo seat. It will sit low and have great balance.

 

Motors aren't cheap, I paid 3800 for a ULH basket, I know of no one making 80 inch flathead motors. I think you will have to build one.
