[QUOTE="AApple, post: 177422, member: 56"] If you have access to a smoke machine, you would be able to see the fuel/air charge as it goes thru the runners. Otherwise, without a really high speed camera, you won't be able to see it with the nekkid eyehole. You would introduce the smoke directly into the throat of the carb, where the air cleaner is(air cleaner off, of course). You would be best able to see the flow during cranking, when crank speeds are lowest. You [b]might[/b] be able to see some raw fuel in the runners if you goose it hard from idle, but other than that, I don't think you would see anything without adding the smoke. That takes of of the visual. As far as seeing what the charge does as it goes thru the runners, it wouldn't be a valid experiment unless you are replacing the entire runner set-up with the clear stuff. If you just cut into the runners, and add the clear stuff, you have now created a different flow path than what was there before, since you have added new "edges", and probably different ID sizes that will effect the flow thru the runners. If you could add the clear stuff, and make it a [b]perfect match[/b] in every way with the runners, it would prolly be more realistic, but....do you really wanna spend that much time on it? I'd be wary of the vinyl stuff at operating temp, too, not to mention how well would it hold up to gasoline. Just for the sake of testing to see what it does, it's prolly otay, but I sure wouldn't wanna ride around with it set up like that without running it stationary for a few days, just to see how well it holds up(or not). All that being said, it sure would be kewl to see the outcome!! :yes: [/QUOTE]
