Pure Bike Porn

A friend of mine put me on with someone who was selling this super rare Harmon and Collins roller cam set up for an A7/10 BSA, and just coming back from the salt has me thinking of finishing up the LSR bike for next year. I have never seen one of these in person and only heard of them for triumph pre-unit nitro burning motors. Cant wait to put this thing together. Enjoy
