In the August issue of Classic Bike Guide there is a chap that has built a B33 based v-twin and put it all in a A10 chassis, anyone seen it? Best bit about this bike is that it all fits within a standard length frame, he just had to modify the front downtubes. Check it out, for my money one of the best specials I have ever seen. Neither flashy or cumbersome, it realy does look like it is a factory prototype.
