Gettin Ram Air On A 97

[sokanxx]

Alright I've been doing some thinking and am pretty well positive that I m missing out on easy power. I'm betting that over 90mph at anything over 80% thorottle My 97' bird would kick much harder if i had ram air. anyone know if there is a way to get ram air on my 97'. i have never had a chance to look at a 99'+. where is the oil cooler on 99+years? would the ram air from these bolt up to my 97' or is there anything avialible to get ram air on my 97'. thanks for any advice you've got for me

you could move the oil cooler an get the 99+ tubes or run custom tubes (which i've thought about)

Talk to Paully (ar50racer) before doing this......

He found that the carbed Bird don't actually like the ram air function. I think it leaned em out wayyyy too much if I remember correct.

Paully????

Pretty sure I remember Paully having problems with his bike when he ran it without fairings. :?

Here's a possible solution to the fuel starvation problem. I haven't tried it as I'm just waaay too lazy to go after 5-6 HP like that.

There is a large number of people who went bald/insane/commited suicide while trying to jet ram air systems..I would not do it,it is not as easy as it looks.

You must also pressurize the fuel bowls also or it will not work.

Beat me to it... good job.

That is correct, you can't Ram Air a carbed bird because you end up pressurizing the carberators first, the Float bowls and the Throttle Slide. So then the air pressure holds the fuel in the float bowl rather than letting it wik it way up the emmulsion tubes, and then you're pressurizing the top of the Throttle slides, in a reverse manner than how it's supposd to work, which will help to hold the slide and your throttle closed.

So.... don't even THINK ABOUT IT! GOT IT !

just trying to help.

Yup same reason you have to enclose the entire carb when you add a turbo, or use a downdraft supercharger to draw more air through the venturi instead of pushing more air down.

[sokanxx]

oh shoot i didnt eve think about having to pressurize the carbs. a very good point! but you all know how it goes mo power is always a good thing!

[JasonW]

Yes, pressurizing the fuel bowls is addressed in Knight's post.

Not to get in a pissing match, but you can Ram-air a carbed application. Pressurizing the carbs is possible and has been done successfully before. McXpress uses the same concept in their turbo system for carbed bikes and from what I've been told by several users, it works pretty slick.

Now, for a few hundred horsepower, I'd go through the trouble, but for 5 or 6 HP, no way.

We work around this problem on drag bikes by building the air box large enough to fully enclose the carbs. You start at the head spigots and just work your way around everything resulting in a snorkel up at the front.

Not worth all the effort IMHO. We did pick up a couple of mph on my nitrous bike when we tried it but it made getting to things a large PITA. The Pro Stock boys are real big on this stuff but they hardly ever go into the box.

Have you all forgot about about the ZX11?

Kawasaki did it by running small tubes inside the main ram air tubes that pressurize the float bowls.

All this does is raise the fuel level in the bowls to richen the mixture the right amount.

It wouldn't be that hard to do.

Honda F-3 did the same thing but the tubes were not inside the ram air tubes. I don't think that it would be as easy as it sounds to get perfect.
