CV Carbs/CB750/Sync?
« on: May 29, 2012, 06:42:07 pm »
Getting ready to put CV carbs on my CB750A.

For anybody that has put CV carbs on their CB750 - how did you tap into the intake track for vacuum synching?

Past bikes - Honda: SL350, CX650C, CB900C, CB1000C, CM450A; Kawasaki: several 1972 750 H2's; Suzuki: TC90J.

Bikes I want: CX650ED, a mid-sized japanese V-twin with ABS.

Thanks - and I was already aware of this option.  I've been advised that the air flow measuring method isn't as "good" as when using a vacuum source.

So, to be more specific - has anybody tapped into the intake tract - so you can use vacuum gages?  I bought a nice set several years back, and that's what I'd rather use, if possible.

Kandy, ask Billy Benton, I'm not sure if the Samauto has these on it.

I found some pics in the SamAuto saga, and I have sent Bill a PM.

Thanks!
