fuel pump or fuel filter fail

Post by Tancakar » Fri Apr 07, 2017 10:50 pm

hi all

just when i was saying everything is ok on my bike she surprise me again. The bike doesn't want to accelerate over 5000 rpm it feels like i am hitting a brick wall and it cuts out sometimes . There are no problems with the clutch it pulls normal, there are no general faults or any type of faults on dash or PC5.

i am taking the bike back to dealer Monday lets see. i will let you guys know.

As painful as these things are, these updates are a big help to other owners including the ones who only want to be told they bought the best bike in the world. I've got my fingers crossed for you.

went to the dealer yesterday and get the bike checked and reset, there was a problem with the air temperature sensor. they say this might be causing the problem. i don't know how but also they say if it does again bring it back.

Clean the filters and bingo - it's all good.... ;)

Doesn't that mean the fuel you put in the tank was from a contaminated supply?

So, it's not the fault of the bike, but the fuel supplier......I don't use cheapie brand petrol stations, only major Aus suppliers like 'Shell/Caltex/BP/Mobil' and I mostly use Aus 95 Octane (we have only 98oct above that and 91 ethanol crap below), but I've noticed I get the best fuel range from the 95 Octane rating and haven't seen any better horse power/fuel range using 98oct.

I'd be changing my fuel supplier - even if it cost a few cents a litre more to get clean fuel. ;)

You sound like KTM's answer. I thought this was a well documented issue? Release agent inside the tank from factory. I have several friends who only used Chevron 94 (best here) that had this problem. Dealers changed filters and rinsed out tank, end of problem. If it really was a fuel supplier issue would not other bikes and cars have the same issue?

:roll: Save the poor readers from word overload - there is no need reprint the content of the previous post - it's just above the reply......I'm fairly confident any sad cases reading this thread can work it out.

Ps I did ask if it was contaminated fuel......and added what I do for general info.

I prowl around the GT section as that's what I own......have started to put some posts in the general area but there's so many different models of KTM's on the one forum it takes too much time to be across these issues - unless they are titled clearly and easily recognised.....otherwise they are lost in pages and pages of comment on various other topics.

I'm saddened that you are not enjoying your GT - I have chosen well and I'm :D to say so. The 1290is not the first fast bike I've owned, nor the last.......but it does put a big grin on my face when I go out for a ride ;)

i only use 97 oct shell v power or bp premium 97.

it must be a hair or something from the petrol station. as soon as i clean the filters the bike was amazing again :) cleaning filters on this bike is so easy you don't even need to lift the tank, the fuel pump is just on the left side corner :)

I just got my new 2017 SD GT in April. I have so much touble with my fuel pump...!
I have only put on 1800km and I riding on my 3th fuel pump now :(
It's covered by waranty so the dealer change all the pump each time. Filters are always jam, full of crap.
I don't know what is it, I hope notting started to be damaged in my tank and stuck in my filter...

Hi from the other side of this crazy mixed up planet!

Might be worth asking your dealership why they have put three fuel pumps on without flushing the fuel tank out to see if the fuel supply was contaminated. From Tancakar's post, I'd say they just replaced each pump and didn't bother to clean out the source of the blockage...... :roll:

At least somebody knows how to pre-deliver a bike - my local KTM dealer must be doing something right as I've knocked up 6,000kms and not had any issues (excepting the hose recall which was a non-issue anyway).

If they did flush the fuel tank then I think your regular fuel stop might be the source of un-clean fuel. Just for info, I only use 95 octane (Aus) non-ethanol petrol and the only additive I pour into my tank is a sip of fuel injector cleaner..... once in a while... ;)

Hope they get it right this time.......bike likes to be ridden....... :D

I'm wondering if this could be problem with mine

So several weeks ago returned from 1400 mile trip - bike ran great / flawless. Parked it, washed it a couple days later, dried it good with compressor and then start it up and let run till at temp killed it and parked it.

Got her out this morning and headed out for a ride so eased along for a mile or two and then rolled on throttle mid hard (not full on) and it bogs badly

Pulled to side of road and changed from street to sport mode to see if any difference - none, same bog

Then noticed "fuel range" is blank actually two dashes --

Stopped by my brothers and we disconnected battery - reconnected and on way home "fuel distance" came back on so I rode on to the house and drained fuel out maybe leaving little less than a gallon as "fuel distance" indicator said 30 to empty

Then I poured in approx 4 gallons 98 octane race fuel I have and went for a ride - went about 5 miles and she still bogs and fuel range indicator is two dashes again

Well heck - so I removed fuel pump and both filters (sack looking filter and normal looking filter) were spotless/clean so apparently that's not the problem



So what to check now ?

Hi Tanc - as I said earlier the filters looked spotless ( I disassembled the fuel pump so I could clean them) I went ahead and cleaned them with carb cleaner and put her all back together , put in the same race fuel I had put in earlier and damn if she doesn't run perfect !! So it looks like it was filters but they didn't look dirty so I don't get it

And yes fuel pump runs when key is turned on

Oh well I'm just glad that did trick as I'm 3 hours away from my dealer

And Tanc thanks for info you had posted above about cleaning filters

Ok........reading and re-reading........but the big question is WTF?? I have over 7,600kms on my GT and it has never had any fuel filter blockage or any loss of power......so why are you guys having these issues?

I really do only put 95/98 Aus Octane (that's prob 92/94US due to the different way of calculating Octane) - no Ethanol - and rarely put a splash (err 70ml) of Valvoline injector cleaner in with a 22Ltr fill up. Nothing else, no octane booster or fuel saver or Moly what the fek, just clean petrol........and off I go into the wild Aus bush ;)...well maybe it's not that wild.......but it is a big country.....long distances between towns etc etc.

Curious to know what you think could be the cause of the fuel blockages. My GT has only seen the mechanic's for the first 1000km service and then for the very quick fuel hose swap. That's why I reckon it's gotta be your servo selling contaminated go-juice.....but I'm a long way away.... ;) so it's over to you for sleuthing the answer.

Cheers from the horses ar....se ;)

no Ethanol
Think that statement says is all Dave, In the UK everything has Ethanol in it. Same as issue with El Capo fuel sender, the plastic they use seems to dissolve in the damn stuff. When I spoke to my dealer about it he said the filters were going soft and collapsing, don't know if that's true.

Cheers Rocky. That sounds very "plausible" in the words of the Mythbuster's TV show...... ;)

I'm wondering if Aussie fuel is slipping quietly into the Euro/US abyss as I have noticed twice after filling up with BP 98 that my fuel bar on dash stays at the low level for a few kms before it wakes up and displays 'full'.

Doesn't happen with my preferred Shell95/Vpower98 or Caltex Vortex95/98.......but of course out in the lonely back country, the servo's seem to be all BP......... :roll:

Hope that SA-Sport is giving you cracked lips from smiling so much! :lol:

Getting used to it, still more vibrations than I would like but grip puppies helped. I feel the vibes more on this due to having to hang on to the beast, Caponaut had a definite power surge as the revs rise where this just puls and pulls until the front goes very light.

Quick shifter is a real blast and when I rode the demo bike last week without one I was surprised just how quick I had adapted to it, felt real strange having to use the clutch.
