how do they compare?

Actually i have to dissagree with Cirian i have an 1988 2kr pre exup and the air intakes are atached to this rubber tubbing wich then runs to the sides of my full tank wich has holes in it then they feed straight into the airbox.

p.s Maybe the earlier models had this set up pre exup

 

Ok I am guessing you are referring to me. I must admit that I don’t know a whole lot about the 2kr, since I have only ever seen one in the flesh. Even though, I am sticking to my claim of no ram air action and hence no direct link from the intakes to the air box.

First off what seems to be the tank on the 2kr is really just a cover for the air box and 'real' fuel tank. I was looking at the workshop manual we have for the 2kr and it also shows no direct link to the air box. The air box intake seems to be the inlet facing straight down the page.



I even think 2kr's have a sticker that has F.A.I. or fresh air intake on it, no ram air. Hope that clears some things up.

 

First off sorry for miss spelling your name, i was mearly saying that on my bike the air intakes actualy go to the air box not to the top of the engine.There are bigger intakes in the fairing, under the ones i was explaining that go to the top of the engine, im not saying that it has ram air intake but i must say it would help with air flow to the air box. I should of made my self clearer sorry <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s -->

 

Are the air intakes that you are talking about the ones in the picture above? They are the only ones that go into the 'tank' I could find. I haven’t ever seen an airbox with more than one intake opening, so I am assuming that the 2kr is the same.

 

would a carb system be able to handle ram air intake?

I mean, the more air you throw into the system, the more fuel you need to add to keep it from running lean, right?

Thus in a ram air intake system, where the air flow increases with the speed, the amount of fuel being injected would also need to be dynamically increased? Which i would assume you couldn't do without a CPU (or some extra machinery attached to the tacho)?

Or is it the case that increased air flow would suck more fuel into the system as well?

 

because if it's the latter, then that would make for an interesting mod to the fizzer....
