round slide vs flat slide carbs

[3 or die]

Well I guess Im comparing my 85r's to my 86. I always had better luck with the 85's

On the bigger round slides 38-40mm etc it seems like they usually have a stiffer throttle pull and you can feel the weight of the slide.

Flat slides r better all around. The reason for one is less obstruction as the fuel and air mix and move past the slide. It's a quicker process with less disturbance. I would recommend them for any application. Just about anything that is left out there today that is still carbed and not injected has a flat slide. I have them on my odyssey's and going from a stock round bore to a flat slide....it is ridiculous that they even used a round bore. I have better throttle response in every range and far more power everywhere, low and high end. How can it be worse low end if it mixes air and fuel faster, more equally, and with less turbulence??
