Keihin Cr 29 roundside carbs
« on: August 30, 2020, 04:49:48 PM »
Hello SOHC genius's, I own a 71 cb750 Honda K1.
I installed a dynatek ignition and new Keihin cr29 roundside carbs right out of the box.
I'm new at playing with these carbs and not sure what has to be done.
When I purchased these carbs, there was this info on the bottom of the add.(see below)

These carbs are spaced for
Honda
69-76 CB750 (SOHC)

These carbs will need jetting per your application

Spacing: 78-92-78
Mains: 120
Mains Airs: 240
Needles: YY8
Slows: 60
Slides: 2.5
Spigot: 020-012
This is for the carb only

- I'm not sure what is needed to be done with these new carbs and I'm also not sure how to hook up all the lines needed to get this running right. I'm thinking the two lines off my fuel petcock, one goes for 1-2 T hookup and other one 3-4 T hookup?
I also noticed other spigot's with rubber plugs and don't have a clue what these are for.
Any of your guys help would be greatly appreciated. Regards.....
