K1 GSXR1000 fueling issues

[carver]

lately the gixxer has had the following problem.
when getting on the gas hard, if i back off, it takes a bit to get going again, and if you feed it on lightly it misses quite bad, and in about 3 secs sorts itself out.
fuel pump not keeping up?

[White trash]

Bad fuel filter would be my guess.

Edit: When did you last change the plugs? They don't actually last for ever.

on the k1 they are internal aren't they, they live inside the fuel pump.

edit, the plugs are iridums, 5000km old~

[White trash]

Dunno. Never had any reason to change one. I can't imagine the fuel pump wont be keeping up.

Maybe shit in the injectors?

[HDTboy]

I wouldn't, that'll block them.

could be, i will run some cleaner through it and see what happens

iridiums are great but wont last as long as standard ngks
a lots or racers use iridiums and replace them every race
look for a fuel filter/replace or clean your pump out
check your plugs aswell

A weak fuel pump would show up at full throttle and high revs. You'd get lean misfiring.
Best thing to do would be get it on a dyno run by someone who knows what they're doing

Yes, but you are still young, Grasshopper.

[carver]

Yes, but you are still young, Grasshopper.

yeah, look at you and steve!
ZX 11 and a bus....a

[carver]

ok, so the filter was dirty, but now it wont start, and fuel just pisses out of the pump outlet freely

the motors do.. its the frames and fairings that usually dont.

I would be starting from square one, cleaning out the fuel tank and moving through to the injectors.

i think their is something wrong with the pump, im sure i have put it together properly

[cowboyz]

got a manual for it? measure the flow rates through it and see if is within spec. should be fairly obvious splutter if its fucked.

[SixPackBack]

Check the fuse bro. If that is okay use a meter to check power into the pump.

it should futter is its slucked.

Got the problem, the O-ring that seals the pump the the base plate was slipped, i thought it might have been something like that, now it runs

just got to put it back together, but it sounds smoother allready

[carver]

ok, cleaned out the filter, a new one is about 100 bucks.
it still does it however, get on the gas hard, back off and pull in the clutch and its like it runs out of fuel, in fact, i do believe sometimes the fuel light does come on.

Can I tell ya a funny story?

Couple of years back when Quasi was racing his horible little 400 and DSS3 had his VFR, we attended a test day at Pukekohe. Lap after lap Daryl was having a major fueling issue with his Honda. He'd come into the hairpin, hard on the picks, turn in go for the gas and the thing would just go "duuuuuuhhhh" (even worse than standard Hondas do. He was seriously getting the shits with it and packed it in and went home.

Did a race meeting somewhere else the was pack for another test three weeks later. Same fucken problem, this time, it stopped dead and wouldn't go again out of the hairpin.

He packed a shit and started kicking things. I thought I'd start by checking plugs and connections having asked all the obvious questions (got gas? Not hitting the kill switch?). Unbolt the tank go to lift it up, it weighs nothing. You dumb bastard.

Anyway, it's often the simplest answer.

haha, its got gas, i will check the plugs next, im running a injecter cleaner too.

after that, im not sure

[carver]

ok, so the plugs have been changed, fuses are sweet, it still does it.
whats next?

[cowboyz]

leads?...........

[carver]

leads?...........

could be, the old plugs were rooted after 5000km, and they were black as.
if you pull in the clutch after loading it up and getting hard on the gas, it just dies

[Sensei]

Have you checked the battery leads are tight ??? My K3 did stuff like what you have posted & ended up my earth lead was loose , Worth a look !

[onearmedbandit]

From memory the throttle position sensor can get out of whack on them. Do a search on it.

Edit - seems that would most likely trip the dash warning light, but still could be an area to look at. A quick search indicated the 2001 model was known to have issues with the TPS.

[carver]

im dropping it into boyds, they can run a diagnostic check on it

bye bye $$$$$$$$$$$$$$$$$$
