just joined up, my name is jeff and i ride a 74 cb750k cafe bike, 810cc's ported head and harmon d grind cam with some mild port work on the head. i'm also a factory certified beemer and triumph tech though i dont currently work at a shop. i'll post pics of my bike asap though you can see it in the ad for retromototoys cb750 cafe seat. it's the blue bike with checkerboard decals. almost forgot, i have a cb500t roller wiht most of a motor and a complete not running cb450 twin. probably going to redo the 450 motor as a 500 and do a bobber build on it.
