you sure can, there are a few threads on here about the benefits of a oko flatslide or something comparable.
what engine are you planning on putting the flatslide on?
the biggest benefits of a flat slide is a almost light switch power delivery, all or nothing lol. you will loose a small amount bottom end but gain a bigger punch up top
Yeah, it seems to be common effect of flatslide carbs, alot of people think its like riding a 125 2t without the outright horsepower. In the way that all your power moves up top.
