how to air box mod f4i
Re: how to air box mod f4i
i just saved a few pictures, took the laptop to the garage and used those to work with
anyways i realized that (at least on my bike) it's not a 1/2 inch t, it's a 1/2 inch t INSERT. the insert means that it fits into a 1/2 inch opening, while the 1/2 inch t has 1/2 inch openings on all sides
so i had to tape up the T pretty ghetto like, anyways
i didn't notice any real difference, if anything (maybe) the low rpm's were a bit smoother when taking off
and how does it make sense that there is a vacuum but no pressure? any kind of vacuum will create pressure if the air has nowhere to release it self?

Re: how to air box mod f4i
doo doo do you think I know the product? No. Do I sort of know the generic PAIR system, D'uh!
D'uh, I know dis much: For every action dare is an equal reaction; so say the crank and air cleaner are a matched set. Say you plumb the crankcase to the PAIR. Say, you dump a bunch of oil down the exhaust and that is going to cook some oil into carbon that is going to close the air reed down, possibly.
All of a sudden you have crank and counter shaft sprocket seals backing up; the vent goes closed.
I'd service or at least look over my reeds I start to re-plumb the bike. Next is that noise you keep hearing? I'm going to guess the pulse is getting a miss-read on the PAIR electric gate, and semi defaults to the backup.
Without hearing the noise, that is my guess. You feel some bottom grunt, but what you feel is the "backup" is Kawi terms and Suz says the "fail-safe" is their legal term for the same generic. So, do we spike the hack to the bottom grunt with a faster set ignition map?
Hummmmmmmmmm....Interesting.

Re: how to air box mod f4i
The reaction you get is polluting the environment, and not hydrolocking your motor, while possibly picking up a little power.
I have probably over 15k on my bike with my clean air mod, actually never even ONCE dumped oil into my exhaust yet somehow
And this is on my 35k mile f4i

Re: how to air box mod f4i

maybe just dump the crankcase breather hose and fill up the hole with something ? it goes into the airbox

Re: how to air box mod f4i
cant really tell from that picture , i would need to see it in person to see where every thing goes but yes bypassing the air box is always a good idea so the crank case vent tube cant put oil in the air box
Re: how to air box mod f4i

ill try to compare the hoses from the f4i with the ones from f4 and see if it makes any sense
Re: how to air box mod f4i
from the pictures it looks like the pair valve is ported to the intake and you dont want to reroute your crank case breather to the intake ...
Re: how to air box mod f4i
the left hose from the pair valve goes in the airbox and the right one splits in two and goes in the carbs, the other one is the outer air vent hose which must stay there for air intake
the crankcase hose goes directly from the motor to the airbox this is why ive said that maybe fill it up will do the trick
