Flipping through a recent (August 2010) issue of Classic Bike Guide, I came across another one of those amazing home builds that look like a perfectly restored factory model, though this model never was. It’s a BSA B66 V-Twin, a twin built from two B33 top ends. The builder is Doug Fraser of Melbourne, Australia, one of those guys who looks at an engine, has a thought that a fellow might make a nice twin out of that single, and then heads off to his workshop and proceeds to build one. Oh sure, why not?
The crank is a combination of BSA flywheels and Harley crankpin plus HD connecting rods. The cams are one offs and the barrels are alloy castings made special just for this project. The crankcase is cast from Doug’s own molds. The 50 degree V-Twin displaces 1140cc.
After all of the talk about electronic components and changing skill sets, a person gets the feeling this sort of build might happen a lot less in the future, which would be a real shame.
Head on over to your local bookstore and see if the August issue of Classic Bike Guide is still on the stands or you can order a back issue from their site. Lots of photos of this very impressive build.
