Digging around in some old images I came across this bike and I have zero information about it but as you can see, there's something very interesting here. Housed in a custom sportbike frame is a Harley Davidson big twin, with 4 valve heads no less! There is some type of induction system with velocity stacks sticking up through the tank and beyond that, you know as much as I do, ... or do you?
How about some help from the most knowledgeable group of motorcycle enthusiasts anywhere, ... that would be you, ... and let's see if we can identify who built this, when, where and any other information you can find. (Updated: mystery solved - see below) For all I know, this is some famous custom I just never saw before or maybe it's a one off that never got much attention.
I enlarged the engine area to give you a better look but that's about as good as it gets.
Since we've talked about big twin sportbikes on a number of occasions and Curt Winter has been building his Big Twin Racers, this seems to fit right in.
OK guys, dig in your archives and let's get some answers.
UPDATE: Wow! That didn't take long. First comment from VMX1000 has the link. Here's all the info on this really sweet build.
1232cc, short stroke, 4-valve, (was an Evo Big Twin), Fueling heads, Cosworth 90mm Formula One pistons, 2 x Weber IDF 40mm twin-throat racing carbs and on and on. 310 pounds!! OK, I am truly impressed! My list of all time favorite builds just grew by one.
