"borrowed" from Paul Crowe - "The Kneeslider" on 7/12/2007:

Chris Barber sent in a few photos of the now completed DesmoHarley, his own unique Harley Davidson engine with Ducati heads, and it is a beauty. A few weeks ago when we introduced you to his project, the drawings were all we could see. Since that time Chris put it all together and it’s the kind of thing that gets a motorhead all twitchy just looking at it!

Here are the specs:
Displacement:
80 cubic inches/1340cc
Compression ratio:
10.3:1
Carburetors:
2X38mm flatslide Mikuni
Pistons:
Keith Black flat top (8.5:1 in a stock 80 inch Harley)

Chris says:

The heads are the early large valve 900ss type, both the heads are rear heads with the front turned around 180 degrees and running a front head cam, this gives me two heads with horizontal fins and orients the carbs and exhausts in better positions for the 45 degree layout.

I didn’t need to do any head work to get a 10.3:1 ratio because the Ducati has a fairly low ratio with domed pistons, so by going with flat top pistons with the extra displacement, the ratio worked out perfectly.

Chris had to engineer his own gear drive system for the cams and it came out great. Specially made Axtell cylinders have their own bolts to attach to the cases plus bolt holes in the correct pattern for the Ducati heads.

That's incredible. I wish I had the know how to do crazy shit like that. Now all he needs is see through cam covers so you can see all the action.

pretty amazing engineering. What's the advantage though, will the harley side of the engine be able to support extra revs teh heads will allow?

i believe the bloke will take care of the rest of harley parts, the lighter crankshaft and con-rod[s] woudn't make a problem for the sneaky bastard! :) a dream engine for fightering buells. that what u can do having a cnc mill and skills to write a proper program for it!
when i made my gear box, i had to calculate center to center distances between shafts, then to calculate co-ordinates for them... but they were flat details, if i had to calculate in 3d space, i'd had burnt my brain out!!! [:0]

"The Mad One' is a member who rejoined, he was originally called "Mad Mundy", hence everyone calling him Mundy mate.
