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

  1. What does the tappet block look like for these. I have a Triumph set of H&C roller cams but no other parts. Would like to see what the tappet block looked like. Also if you hear of another set of tappets I’d be interested in them for a fuel drag bike I want to build. I’m a Bonneville racer. 1955 VG Panhead 140.6
    my email is bucksbike27@msn.com to send pic of tappet block? Thanks, regards
