Intake trick for GS1100/1150 for the drag racers

[stetracer]

Not sure if any of you know about this but if you take you #2 and 3 intake manafolds swap them with the #1 and 4 Basicly put the insides on the outside and visa-versa and rotate them until they are all lined back up I use a ruler to make sure they are flat to each other This will take the curv out of the intake path and give a strighter path for the air to travel at the track it gave me almost a .10 of a second and solid 2+mph on my 82 Katana
Look at the carbs on pic of my katana and you can see what I am talking about

I am a bit puzzled.

The parts fiche shows "Left" and "Right" intake tubes, but does not differentiate between "Inner" and "Outer".

In other words, since #1 and #2 are the same, what is the purpose of swapping them?

.

[Agemax]

so swapping 1 & 2, and 3 & 4 is the same as swapping inner and outer but as Steve says, they are the same tubes so what difference will it make?
do you mean turning them up side down?

and your pic doesn't really show anything!!!!!!!

[stetracer]

I am sorry I stated that incorrectly it is the left with the right it had been a long time ago I did this . If you look at the angle of the carbs in the pic you will see what I am talking about

Maybe if the picture was bigger and pointed at what you're talking about. It just looks like they are pointed down too steeply.

old news as suzuki will sell you 4 rights or 4 lefts for an 1150..what ever they have on hand...#00A L L R R

you can flip the rubbers and use on the opposite side.
makes sense?

I know it's old news for some. I just thought I would put it up for those who did not know about doing this. Anything free that helps with lowering the et and brings up the mph. It only takes a little time

Not too steep it's just right. I had to down size the pic twice to get it to load sorry about that plus it is a pic of a picture I have.

sorry about being a dick..happens sometimes...well a lot of times
now i see the performance part your mentioning.
not doubting you...just never seen 2/3 hp from what your speaking of.
sometimes things just happen and we never find the perfect run...sometimes we just make a little here or there and pick up et/mph.
it just happens.

I did swap them back one time during a test n tune session to prove the point to a fellow racer and I did lose et and mph that I stated and gained it back when I switch them back the way I had them. As far as the perfect pass I had made at least couple hundred passes on that bike bracket racing it every weekend. I race no bar bikes most of my racing days and that Katana was a very consistant bike. I bracket raced with some of the toughtest competion around in Bradenton Florida. I also have had 3 bracket wheelie bar dragbikes in the past and I have a GSXR 1100 Dragbike I am putting a Bandit motor in trying to get it ready for some April racing at Bradenton I plan on running in Pro Et and Street Fighter classes If my old ass can handle it. Here is a pic of the GSXR it is a fussy phone pic

Here is another pic of the Katana I but you can still see the carbs are straight with the intake track

i also see the L model forks for that extra 1+ inch of wb out front.

I can see a guy with a blue jacket on a Katana, that's about it.
