Very busy these days & no time to teach myself on this one. Got a 77 CB750 F that needs some carb adjustment & possibly a jet kit. It runs pretty good, having issues with backfiring. We eliminated the airbox & went with K&N pods. Also upgraded to a 4 to 1 exhaust with open pipe, no baffles. Based on this i am sure we need to re-jet. Carbs were recently rebuilt; floats, float needles, o-rings, gaskets, etc. Like i said, short on time and hate working on carbs! I am in Hilliard, (columbus) and have a good space to work in. PM me if you want the job. Looking to get it done asap. Thanks!
