Beeza Bill's BSA A10

Welcome to my Home page. This is my BSA it's, a 47 frame with 52 crankcases, 55 RR twin carb head, thick flange barrels and large journal crank. If you like A10s and are into performance with reliability. {oxymoron?!!}I hope you will take the time to explore these pages. I will be putting up information on many of the modifications and parts that I've made and other info relevant to A10s. I have for some time used this bike as a test bed for the Caf' Racer I am building, but never seem to finish. While the above bike is off the road due to frame, oil and fuel tank fractures [Metal fatigue, vibrations?]. I have taken this opportunity to strip the motor and cleanout the sludge trap. When assembling it I will photograph the roller bearing conversion I did and many other modifications. I hope you enjoy it.Please allow the pages to fully load before exploring as there is alot of pics and diagrams.Use your browser back button to return to this page.
