Rotary vs slide
So let me know if I'm wrong. The volcano S30 has the sh eng with the rotary carb, but the T2 has the same eng but with a slide carb whats the differents? I think the slide carb must be better but in what way? How much more performance do you get from the slide carb? Can you put it on a S30?

RE: Rotary vs slide
yes the slide carbs oben faster giving you better acceleration, but i dont think the slide carb will work on the s30 because of where the throttle/brake servo is mounted

RE: Rotary vs slide
you can make it work, just move where the bracket that moves the carb towards the front. I dont see it being much different though, because it will open what like half a second faster? plus if you get a faster servo it will be just the same right?

RE: Rotary vs slide
popular opinion is that one gives finer control in the middle of the travel and so is good for off-road, and one give finer control at the top of travel (i.e. WOT) and is better suited to on-road. Frankly I don't see why that would be the case, so ultimately it comes down to layout of the vehicle - if the servo is in-line with the engine then you'd use a rotary carb, and if the servo is beside the engine you'd use a slide carb.

RE: Rotary vs slide
i do know that in the dirt bike 2 stroke world, flat slide carbs give faster. crisper throttle response.
It has to do wit the fact that with a flat slide carb, you are esentially sliding a flat plate up & down (very simple movements) where as with a rotary carb you are rotating a "drum" which takes more work.
but we're talking micro-seconds of difference here, but that amounts to crisper throttle response.
much like fuel injection vs. a carburetor.
but i don't really think that you'd see a huge difference by adding a flat slide carb.
it won't be like going from a rotary carb to a flat slide, will give you a huge boost like you just added nitrous oxide.
you may see a little performance difference, but i don't think it would be a night and day difference.
If i'm wrong, someone please correct me.
