Simple speedo advice

morning all, im looking to get a nice small speedo for my '74 cb750. previously ive been running a small push bike speedo but i think its time to get something a bit more professional looking fitted. i liked the push bike speedo as it was small and neat but it required a sensor on the fork which looked a bit tacky. im thinking about going for one of the small ~60mm clocks but not sure where to mount, bar mount? fork mount? tree mount? The top yoke on the bike has been trimmed (the horn removed) and i really like the tidy look of this section so wouldnt want much mess around there. also looking to get a speedo with build in idiot lights to further tidy which could rule out the small fork mount speedos via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/8f9jfy/simple_speedo_advice/?utm_source=ifttt
