Carb Question

[01CandyBlue]

I am putting together my banshee on a moderate budget and dont want to go to extreme with it, I have the usual, Head,Portand Polish, Pipes, V-force 3's, Flywheel Lightened, Wisecos, and other small things, im wondering if boring the stock carbs would give me much more, im thinking thats where im being restricted and I have the equipment to bore them, my question is, if i bore them to 29 mm what happens at idle with the slides, whereas they are only 27mm there will be air bypass on the sides of them, do you just compensate with the idle and this is a worthwhile mod? I mean eventually i would like to buy carbs but with my college student budget it will be some time

thanks

You will not have good luck boring the carbs to 29 mm.... The slides are 27.35 mm, so there would be too much air leakage to compensate for and have it idle.

 

What I do is oval bore them to 26.25 X 28 mm, I also install one of my divider plates. This set up works great and gives you the best of all worlds, good bottom end response and a good top end.

You dont want any air flow around the slide. Oval bore might be one way to get a little more total open area. You might also consider getting a pair of 28mm flat slide carbs, they'll fit the stock intake and airbox boots and flow better than stock carbs, so it'll just cost you 2 carbs and a cable, about $250.
