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~

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

Maybe shit in the injectors?

I wouldn't, that'll block them.

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

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.
