:welcome1:
hi graham and enjoy the site and the 1400 family :onya:
nice looking bike best colors :boogie:
:welcome1:
enjoy your in the right place for all things 1402
nice bike too :cheers:
Hi Graham - glad you made it over
Del (Sir Jimmy on FB) :grin:
Welcome Graham - nice looking 14!!
Welcome mate
Welcome :smile2:
Hi Graham. Welcome along :)
oh oh a Blue one! They look much better without that spunky White colour :stir:
Welcome on board

That's a nice bike!
Welcome aboard G14!
:cheers:
Stan
Evening and welcome,cool bike ;)
Welcome.
(I quite fancied the blue model myself, but the wife wanted the B&W and I have to do what I am told).

Thanks all nice to hear fro you all hopefully get some good pics up the future of mine out and about.
Though currently she is very poorly
your in the right place
tell us whats wrong and I'm sure folk here can help get it up and running as it should be again :boogie: :cheers:
Thanks Seth, do I explain it here or another tab? I'm currently investigating it myself but any assistance would leave me very much in everyone's debt.
Welcome :salute:
What wrong with the bike Atm?
:salute: blubber hello
Well.. Im getting her back on the road for the season after a full strip down to have the frame powder coated (no engine work at all) and put it all back together, cleaned the fuel filter out, fresh fuel and then this happens.
1) Start engine, it misfires, coughs, farts, doesn't idle, pumps out black smoke then cuts out.
So changed the plugs and coils. No fix.
2) Disconnect fuel pump, thinking it's a dicky pump, engine starts and runs (10 secs or so) seemingly absolutely perfectly fine until the rail runs out of fuel. Then naturally it stops.
Repeat process 2) and whilst engine is running (within the 10 seconds) I re-connect fuel pump, and engine instally behaves like process 1).
:whatever:
Welcome aboard !!
Sounds like a fuelling issue for sure. You may need to reset your TPS, instructions are stickied in the Fuelling section.
Also check that the fuel tank overflow pipe (the one that goes down behind the swing arm) isn't kinked. You may possibly need to balance your injectors. This might also sound a silly question but did you get the right plug caps on the right cylinders?
Do you have a PC3 connected? If so disconnect and see if that makes a difference. Also check all earths are good

That was my first thought too :confused1:

Hi Barmy I was thinking fuel too, but how does an engine run better when the fuel pump is disconnect ???
yes all plugs are connected to each cylinder in order, as it runs perfectly ok when the fuel pump is disconnected.
I'll look at the TPS I didn't know about that. I did adjust the throttle cables upon re-assembly perhaps that's caused it?
The only earth I have is the battery negative onto the engine..?
Froudy would know better having just done a similar exercise to yourself, but vaguely remember someone in the past mentioning an earth strap at the back of the engine? Might well be wrong it is only a very vague memory.
It makes no sense that it runs better with the fuel pump disconnected - unless when it is running the fuel pump itself is over pumping, so when it runs ok, it's really using residual fuel.
Just a thought - the very small rubber hose that fits on the injector rail (the one you cut to fit a Scottoiler) - no airleaks from that? Personally I'd check all your electrical and hose connections between the tank and the injectors, as I'm pretty sure that's where your issue lies. Actually a thought - you didn't adjust your choke by any chance such that she's over fuelling by keeping the choke open?
I think a check over that all the various sensors and the suchlike are properly connected first would be useful. If after all that she still doesn't run right and your TPS is good, it may be your camshaft position sensor giving grief, there's a thread I responded to on that a few days back about how to,check, let me find it and post the link
Here you go, scroll down this thread, extract from manual about how to check the camshaft position sensor
http://gsx1400owners.org/forum_test/index.php?topic=618.msg5756#msg5756
Thanks Barmy, that's a great link, seems as if the other chap has a very similar problem to mine. I'm going to release any undo tension in the throttle cables, spray all electrical contacts with cleaner and check the cam sensor voltage.
I didn't adjust the choke at all but could have knocked something?
What's the typical procedure for the pump? Does it run all the time?
In a sense it does - that's the whirr you hear when you switch the ignition on, so it will pump according to needs - but if it's getting the wrong signals - I.e like from the camshaft sensor then it's not going to deliver the correct amount of fuel at the correct time.
Let us know how you get on and if you would be kind enough document what you do, as documenting the resolve of this could help another out.
Welcome Graham :hat:
Hope you get your running issues sorted mate. There's some well informed guys on here that should be able to help you out hopefully!
Gaz
Welcome to the forum Graham, hope you get it sorted before the sun shows up :)

You make one mistake and it sticks for life!! :facepalm:

hi graham
hope you can get to the bottom of the bike issues .... i know how you feel ive being there good luck mate :onya: there is plenty of help here just shout
Thank you all very much, I'm investigating now so will update as soon I know more.
Update:
I'm now convinced it's electronic of some kind.
Routing around the wiring loom checking all plugs etc and come across this little thing. Now seeing as it says "race use only" I'm assuming it's not factory fitted.
So unplugged it and connected the two harness plugs back together and she idled and ran perfect for 2-3 minutes no problems at all so thought ahh! Solved! But then upon giving a few revs, she quickly started misfiring, pumped out black smoke and cut out.
If I re-attach the little box or keep it removed it's still misfires and cuts out. back to square 1 again. I'm thinking has this box upset the main ECU or something? Or does now all sensors need re-calibrating?
well i am pretty sure ive not got one of them on my bike ........ ??? unless it hidden ive never seen it ,,, got to be some kind of mod
Hi Mrg
I've been doing research and it's a box that connects in between the gear seletor sensor and the engine ecu. The ecu has got set 'maps' for fuel & ignition delivery depending on what gear you're in.
Basically the maps set by Suzuki restrict fuel and spark when in certain gears for eco reasons. This box blanks out those signals, thus allowing the ecu to deliver the fuel and spark the engine needs when it want its, instead of the ecu telling the engine what to do.
However this is not the problem I thought it was, as I've been digging all day to find out.
This little sensor was missing its little rubber hose from the bottom which terminates on the throttle bodies. I thought this was some kind of temp sensor. Clearly not as when I connected the awol pipe I had - it to (not thinking that it's actually suppose to be there anyway) started her up and bingo. All perfectly fine! Obviously this is some kind of vacuum sensor.
Bottom line.. I forgot to connect a pipe. :facepalm:
yes i did have one like that i had a Scot oilier fitted and when i took it off to clean and service and remount latter ,, i didn't know about the vacuum pipe connected to the throttle body ... cos it used the air vacuum to draw the oil around the pump ,, as i understand it ;;; well i didn't block this pipe off when i ran the bike for a short while ,,, and it made a difference in running ,, so now its back on its all ok but i had the small issue of my camshaft sensor but that is all ok now :onya:
Remember I said about the little vacuum hose.................so that was the one eh? Well found that man! Glad all is now good
As for the S-TRE - What it does is advance the ignition 4 degrees in gears 1-4, arguably giving slightly tauter acceleration. So if you ever fit an ignition advancer take it off else you will double advance the ignition

you did mention the vacuum pipe and you were right my Jedi master :onya: :onya:

Thank you - Just lucky I guess :whistling:
You did mention about a pipe yep, and I thought it was sorted as the one I was looking at was the one that's connected to a 3 way diaphragm of some sort which splits off into two bigger pipes going to either side of the cam cover.
Turns out there's 'two' pipes haha! :doh:
Thanks all :worshippy:
glad you found it and all is well :boogie:
Nice find, to bad you can't blame anyone else but yourself :frustrated:
Graham..
That is the IAP sensor. The hose has to be disconnected from it to balance the throttle bodies. If you forget to reconnect it, the bike runs like a crock of sh*t...
Been there and got the t-shirt :imrgreen:
Now she needs a 9 Grand tune-up! :jack:
