1972 CB750 SOHC
Ok so I am new to this forum and I have been searching around to see if I can find some help with my bike. I recently purchased a 1972 Honda Cb750 SOHC for $600. Lots of customs and mods. Here are the details that I am aware of:
-Accel Super Coil 140403 coil kit (NGK D8es plugs)
-Four straight drag pipes.
-Pod air filters.
-657B AMH carbs.
-new boots from carbs to engine.
I am new to building bikes and I need some help.
I just took the carbs apart and cleaned them. The first and second carbs had a little gunk in them but other than that they were not too bad. The bike will run and idle fine but whenever I take it out and ride, the bike doesn't run well at all. It keeps cutting out and kicking randomly as well as a few backfires and popping. I don't know whether this is because of fuel delivery or because of the pods. I have read that the pod air filters are hard to get to work on these motorcycles. I have been checking for vacuum leaks and I do not believe that there are any. The boots are all new and sealed properly. I do not know if the previous owner re-jetted the carbs when he put the straight pipes and pod air filters on. Is there a way I can check the jet sizes that are currently in the carbs? What jet sizes would be recommended for the set up that I have? I am looking for any and all help. Like I said I am new to the cb750 and I want to learn. I am in college and would like to make this a permanent hobby of mine. I know that there are already threads on this stuff but I have not found any on bikes that are specifically like mine. please bare with me I am new to this forum.
PLEASE HELP!!
Thanks,
Matt
