I am at a similar stage as you with a B33. So watching with interest. I was trying to post a pic of the B31/3 tuning notes. But am suffering technophobia. The only stuff the basic notes say is to fit touring cams and a 7.5:1 piston. Yours looks to be a 6.8:1 piston. Like mine. Bear in mind there are two types, depending on long or short conrod. But you seem to be on top of things. I've been on a learning curve, with this motor also. I did just buy some goldie cams from ebay, so may have some standard ones left, at the end. Regards Steve.
