Something has taken a giant shit and it sounds expensive

[SNF]

Thoroughly bloody disappointing. Was having a great little ride on the FZR. Leading up to this it bogged down once taking off at a set of lights, came right and ran fine with tons of power and didn't do it again the rest of the day.
Today it did the same thing, bogged down. Then riding it, it gradually lost power and sounded like it was on 3 cylinders. The fuel pump makes a racket and when it does run it sounds..... well nothing like a smooth running 4 cyl sport bike should, runs and sounds like crap and dies. Can anyone suggest what it could be?

My guess is/was plugs and leads but it sounds really sick, like it could be something else I have no idea what. Thank you for rescuing me Glowerss. Would be keen to ride again, next time without breaking down.

Well if the fuel pump is making a lot of noise, could be a good place to start. What sort of pump is it? just a low pressure one to allow the fuel level to fall below the carb bowl level?

A good place to start ... and check any fuel filter in the lines between the pump and the tank. Including the filter in the tank that is (should be) attached to the tap.

If they/it is clear ... disconnect outlet line off the pump and turn key on to check its pump flow. A temporary line into a container is a good idea.

And look for kinks and leaks in the line between pump and carbs.

With the engine off but key on ... is the pump still trying to pump .. ??? (it should get to pressure and stop)

My fzr1000 fuel pump died if that helps.

get a gravity feed fuel line onto your carbs with your tank up high and try that (bypass the fuel going through the pump).

he can probably get away with just filling the tank up (and bypassing the pump), commmonly done on bros's to check for the same fault. Then we just upgrade to mikuni vac driven fuel pump

All good got it home. Now running fine. The problem? Fuel blockage, guess all the hills and corners stirred up some crap. Changing the fuel filter and getting for fuel system cleaner

If 3/4 full will work. Might not keep up when revs are higher.

vac pumps can be a hassle on bigger fzrs not sure about 250s. there would be a few jetski pumps that would work if a second hand fzr250 pump is hard to find.

Anyone out west with a van or trailer that can tow it to my place? Can offer $50 for the trouble. I parked it at a dairy in Woodlands park and need to get it home. I think you guys are right the pump is dying. Its got 1/4 tank or so of gas and there's no gas station nearby, once home I can try fixing it.

take a 10litre fuel can with you and it will most likely get home on low revs even with the pump still connected.

Glad things worked out OK for yah mate, and it wasn't anything serious.

what he said. start with the funny noise at the pump.

[McFatty1000]

Be very keen to see what becomes of this - my bike hates starting off from any incline and I get the feeling the fuel pump is on its way out on mine too, no real noise yet though, just the bogging when looking uphill without a bagillion revs.

And as for a ten litre can, that'd mean carrying around a second tank for these bikes?

Meh, heck, shows I'm only skimming through.

On another note, has the noise settled?

He did say "All good" so I assume that's a yes.

As for your issue ... check all your filters. Including the air filter. (Even if it was last week you cleaned it)

Then check your plugs ...

[SNF]

Pump works, it makes some noise at first when its purging all the air out, its a vac one and they all do it from what I hear since it was rather low when I broke down it kept purging and making noise for ages which made me think it was dead/dying.

I called Kevin (Motorcycle Recovery Specialists). Great guy he got me and the bike home definitely recommended. Turns out it was probably low gas and possibly a fuel blockage from riding around in all the hills. I drained the tank, what came out seemed clean. Got a new fuel filter and changed the plugs while I was at it. Rode around the block a couple of times last night and it seems fine now.

Crap I completely forgot about the air filter. Will change that soon, the guy before me did stuff all maintenance. I had the oil and filter changed when I first got the bike.
