Bill Connor is widely recognized as one of the world’s leading builders of model I/C engines, specializing in racing motorcycle engines. He has built a number of half-size engines, working replicas of his full-size engines. All measurements of every component are taken from the actual engine making all his models as close to scale as practical. The operative word here is ‘practical’ as all the engines run perfectly. Even though these are large models, no castings are used. Everything is machined from solid.
