OK, Thank you in advance, two weeks ago I bought a CB750 bobber project, I was told the engine was a 76...after getting it wired and plumbed and running My brother and I found out that the throttle cables from his 74' cb750 wouldnt work on my "different looking" carbs..After some research on the web It appears that the bike has a non-matching set of carbs with the power plant. My case numbers read CB750E-3012064 My carbs look like the Hondamatic carbs I believe they are "a" series? In anycase should I sell these carbs and get the correct year carbs for it(bike runs fine, idles great, havent physically been ridden yet. Any info would be great.
