I agree - likelihood is as Seth says is that they just need re-seating Mark

Spray 'em with CRC Soft Seal, that'll close off any wee leaks.

I wouldn't think anything will change there Mark.  They are adjusted with screws from the rear.

If your airbox is naf, thought about pods?

I don't know if it would require a new map to be honest.  Can't see why it should though.  Blubber or Seth would know though.

This posting reminds me what happened to me 10 years ago, went to cold-start the bike, & whilst the button was still being pressed, there was a turbine-like whistling sound immediately followed by a loud whip-crack, right under the crown jewels, frightened the bejeesus out of me!!
This was the result, & upon inspection, I found the O ring to be very hard & brittle, now whether the was cause was BY the breakup or BECAUSE the breakup, I don't know.
The bike was only 5 yrs old & I bought it new, never been touched & at the time only had 5k on the clock, & i've never heard of this happening to others, the offending intake rubber had to be special order as well!!

As far as I am aware air box is the same across all models - but would be a pig to change Mark, possibly engine out, as its not easily removable, this not easy to put back in place.

Just one thing that I can't quite get my head around - when you say if you spray the air box, the engine eventually stops - its not because the spray is getting sucked in through the air filter possibly? In fact could it be the air filter that's the issue, whilst it may look ok, may be worth putting a new one in for what it costs just to eliminate that possibility, as a lot easier than changing an air box over.

If you do decide to fit pods - http://gsx1400owners.org/forum_test/index.php?topic=257.0

If you decide to remove your throttle bodies - http://gsx1400owners.org/forum_test/index.php?topic=338.0

Regards mapping for pods - I don't think the 14 needs it, but as others have indicated, Seth or Blubber would know

I would not recommend running pod filters on a stock suzuki map.

Maybe a yoshibox tune will suffice but that would still mean some dyno / rolling road time.

I had a yoshibox tune done on my 14.
I felt this was needed because I changed my link pipe and exhaust can. The operator  got the afr into acceptable values but NOT spot on.

The cost of this ease of mind was just below €200.

He recommended a Powercommander or the likes eg. Dobeck.
I later choose a Powercommander 5 with the Autotune module with future mods in mind. (GSX1700 with full akrapovic system and pods)  not all is realized but I am prepared.

Hope that helps

As for the original problem:

What Dave mentions....sucking the spray in via the air filter is a viable option.

Other option for sucking air: the airbox has a hose connection to the crankcase breather.  that hose could be loose to.

Just a thought.. The area you are spraying houses a sensor: the IAP. ( intake air pressure sensor )

The intake air pressure sensor is located at the upper frame between
the tubes and its vacuum hose is connected to the throttle
body.

This hose can deteriorate. Even the sensor housing can be cracked

not understanding your reasoning, youre spraying fuel into air box, it cuts out because of too much fuel, of course it will. explain your initial problem a bit better. i think air leak is a fantasy.

as blubber said you'd need a remap for pod filters .
if you remove the throttle bodies ot would be worth getting them balanced (might also be worth checking them as part of the fault finding too)
removing the airbox is a nightmare if your wanting it back in again as its fitted before the motor when first built new.
one of the Scandinavian guys did get 1 out by bending a frame lug then bending back and painting after but said it was a pest of a job.
i think there is nothing wrong with the airbox but you might have a leak from 1 of the many hoses going to the throttle bodies or airbox .
note the smaller hoses are different sizes even tho the look very similar.
thats what I'd be checking before taking the bike apart.
my wifes 14 got moused and these hoses were damaged some only very slightly but affected the running lots.

You do have some weird problems on your bike Mark!

To be honest if it's just a slight drop in revs and its not affecting performance, I wouldn't worry about it. Probably a lot of 14's do it and their owners don't even know, after all these were mass produced, not hand crafted to exact tolerances. At a guess it's a very slight gap or pin hole leak around the air box, which if it hasn't affected it to date, probably isn't going to in the future.

Myself - I'd not worry about it if it's all running well, but put it down as one of the "features" of the 14 - of which it has a few after all!

if all hoses changed that cost £700 from suzuki as i did replace all emma's one's some of the longer one's did 2 so actually using saved hoses and new cost £300 .
i still can't see it being the airbox (tho nothing is impossible )
I'd still be checking throttle body balancing .
only other thing to check is where the 2 sensors go into the airbox and the seal around the airfilter .

the pipes are different size
its my wifes bike and as with my bike i don't bodge the repairs as we do 5000 miles a year in europe I'd rather do it right than have trouble over there.

glad you fixed your bike if you look i did say it was unlikely that the airbox was faulty but said to check everything.

as I've said before your bike has had some life with all the faults that nobody else as ever had especially at such a low mileage.
your the first with a split airbox I've heard from and ive had 14's  and been on yhe org's since 2002.

if there's ever another MCR then you must be up for a prize of some sort

i said we do 5000 miles in europe
i live in scotland and everywhere is along way from there .
all 3 of our 14's are used all year round im on my 7th emma on her 1st but done 50000 miles on it.
the pipes to the throttle bodies are a different size to the others that go to the sensors so glad you have both sizes.
i used genuine suzuki parts as that's what the insurance company wanted invoice's for and paid me for the labour so worked out costing £50 to fully repair her bike.
you need to thing about what your posting as folk will try to help but you then slap them down they'll soon get fed up of the way you ask things.
also you seam to be able to do the work and fault finding so have more confidence in yourself and work.
good luck with all thinks 1402

:cheers:

All fixed thanks I like a good running bike not just live with slight faults like most people and to the people saying it's not the air box well I whent round the join line of the air box with a hot glue gun and it's running perfectly.. And as for spending the money on pipes I think suzuki seen u coming at that price geez fuck paying that I whent auto quip got same diameter pipes. Total cost was 25 pound for the pipes.. Fit and work so all good

Well that's a first - never heard of a split air box before either on here or the previous org - well found! (you do get some odd problems Mark!!!!). Odd though, given that the air box takes air in you wouldn't have thought a little extra would have made much (if any) difference. Just goes to show.

Might be worth balancing your injectors now you've solved the air leak Mark, just in case the leak was there (but perhaps not so evident) last time they were balanced.

Eight 1402  :worshippy:

That makes for a bit of experience!!! What happened to the previous 5? Crashes and or the salty environment caused their demise?

K2 b/w sold with 35000 in it to make room for my b/w K6 that i still have (the heavily modded one) sitting at 57000.
K2 b/w sold on with 15000 miles added
K6 b/w sold on with 25000 miles added
k6 b/w bought when i went to buy a clutch seal kit got a good deal on it in the local dealer
sold on with 20000 ish miles added to make way for a BKing an itch i needed to scratch but it wasn't for me so part exchanged for the red/black K5 currently added 12000 in last summer and a bit.

and emma's K6 black(with custom paint job)

number 8 who knows if i see a low mileage K6-7-8 then you never know.

really enjoying the standard K5 red/black bike  did a wee 1400 mile run around the Netherlands, Germany, Belgium and Englandshire a couple of weekends ago.

well not all the 1st K2 was crashed and scrapped by the guy who brought it from me .
as far as i know the others still live and share good homes.
a couple of the guys who got my old 14's did join the old org but there not here .
