Carbs are dead easy to get at on an SV, just take out the air filter (or the airbox if you need more room to maneuvre, obviously that'll make it run a bit different so this may queer the results... (this is how I diagnosed my front cylinder fault after I fitted the DJ kit, looked in the top and saw the needle flapping about
)
I've not measured the intakes, but I'm sure they're bigger than an inch. They flare out a lot at the top as well.
Setting up most proper vacuum guages sets seems to be a real hassle,

I'd get a dealer to do it if it has to be this difficult, but the Carbbalencer looks like it might get a decent result without the futzing about. I think I'll give it a crack, it's not expensive anyway
