Okey I was asked to post some pics of the 34mm carb mod I did on my Bobber. Things to aquire; one set of carbs from a 1990 or later CB750, one set of intake clamps, 4 each 30 degree silicon tubes, and some card board.
Make a templet of the carbs intake runner side with the card board, (this needs to be done because the 90 and latter model carbs are a touch closer together than the 30MM ones)
Then it is just a matter of cutting tue tubes for the proper angles to go from the head to the carb templet. (a minor note here is the both sides of the tubes will need to be cut to acheave proper angle)
The throdle cable should line up with minor adjustments, the pull close side just gets crimped around the cable housing to keep it in place ( I'm working on making a new bracket for it)
Jet the carbs as needed depending on the needs of the engine and enviroment you live in.
