Topic: 1980 750 Carbs on a 72 Motor

[cfocats]

I have a 72 motor in my chopper frame, clearance and cabling is not an issue, will the carbs fit my intake boots? and is this a good idea, or a really stupid one?

80 750 carbs are cv's so I dont think so.

What exactly is the reason newer CV carbs couldn't work an old sohc?

i imagine that they could be made to work, but why? you may have to futz with the rubbers (or make your own from radiator hose), as i am pretty sure that the intake spacing is incorrect... it is a fact that DOHC exhausts are not interchangeable with SOHC for this very reason...

[cb650]

Spacing is diff.   At least when the 650 changed it did.

in general try to avoid the DOHC cb750/900/1100 carbs whenever possible. They aren't even good on the bikes they were designed for (CR flatslides are popular replacement).

As a general rule constant velocity carbs don't give good throttle response and are difficult to tune on engines they were not designed for.
