ER6 running problem

[Drew]

So nobody's managed to solve Drews problem yet then?

I'll beat the rush. No one can solve my problems.

Unless than can tell me why an ER6 would run like a bag of shit after sitting for a couple months.

Condensation in the fuel?

Condensation in the fuel?

Possible, I pumped a couple litres out after I'd taken for a hoon, because I thought water in the tank. No water in the bucket so I've kinda moved away from that theory. Fucky symptoms have got me totally fucked.

Started but ran like shit. Took for a ride and it wouldn't let me use much throttle. Took for a longer ride and after gently easing it up to speed on a twisty road was able to give it a thrashing. Back on the straight roads at 50k's, and runs like shit again and doesn't like throttle again.

If it wasn't injected, I'd have the carbs out getting rid of the water in them.

Because it's missing two cylinders.

Or you've got a shitty maf or 02 reading

Please elaborate on why that is your guess. The fuel mixture sensor thing, you're spot on with teh missing slugs thing.

My idea if petrol's okay:
Air leak. Bike's probebly going to be a dick of a thing at small throttle openings/low load.
MAF sensor (if it has one, or MAP sensor) will not be telling the ECU how much air/pressure is going on as a leak could happen after it
02 sesnor being bung/sad/unplugged will not be delivering a voltage, but I expect a check engine light may come on if that was open circuit.


Why does my 74,000km old Kawasaki flip-mobile works beautifully after not being used for yonks? :bleh:

No engine checks come up, so methinks it something simple.

Will drain the tank completely tomorrow and go from there.

[Drew]

Well done whatever mod moved this. I hadn't intended on having a big discussion on it.

[mossy1200]

Low voltage.

Whats the voltage at 4k revs and idle like.

[steve_t]

Gummed up injectors?

Couldn't see it, starts convincingly even after leaving it turned on with the fuel line off to pump out the gas, and having to thumb the starter every ten seconds to get it to pump.

[FJRider]

Sitting for six months ... fuels gone off.

Drain and fill with fresh ...

[Drew]

Sitting for six months ... fuels gone off.

Drain and fill with fresh ...Two months.
Gotta drain the tank anyway, so might as well use the old stuff in teh V3000 instead of the bike and eliminate a possibility.

[Drew]

A horrible thought that did scream at me from the very get go, we're ignoring the issue so it can't be that.

[FJRider]

Two months.

There is an injector cleaner that can be added to the fuel ... might be worth a go too ...

If the fuel level in the tank was low when left ... the fuel does go off quickly.

Shouldnt it keep pumping until it sees pressure?

[ducatilover]

Probably just priming it so there's less current draw when you hit the starter?

[Drew]

Shouldnt it keep pumping until it sees pressure?I used to think they pumped untill the pressure was right, but in fact the fule pressure is set mechanically and the ecu never knows anything about it.

If it's a vaccum line ... the pump starts when you turn the key on. (if fuel pressure is down from that set on the pump) Turning the engine over opens the vaccum tap and fuel flows .... fuel pressure drops and the pump restarts.

[Bassmatt]

Apparently the stick coils, or whatever they are called, have a habit of fucking out.
?

?Oh fuckin excellent. Might look into that. Weak spark fits the symptoms pretty well.

[White trash]

Do the basics first. Replace the plugs.

Why does it need a vacuum tap?
I'm willing to bet it primes when switched on (fuel isn't going to go past the injectors with engine off, no need for vac tap)
Then maintains pressure once the bike cranks/starts.
Fuel pressure would be set by a vacuum referenced pressure regulator after the rail.

Do the basics first. line of coke and a skid.

Agreed

The vaccum tap (valve) only opens when the motor turns over. When the key is switched on ... it can only pump/prime with the fuel in the linefrom the vaccum valve and the pump (as the vaccum valve is shut) .... and pressurise the line from the pump to the carb/injector.
Electric fuel pumps should cut out when their set maximum pressure is reached. (the sign of a well set up fuel system is when you turn the key on and it doesnt need to pump) They are usually variable flow pumps ... so as to slow pump when fuel use/flow is slow. (At low speed/rev's) and full/higher rate at the higher speed/rev's)
From memory ... injectors require a very high rate of pumping pressure.

It doesn't have a vacuum tap, it has an internal fuel pump.

[bsasuper]

Pull the vacum line off the fuel pressure regulator, prime and see if fuel comes out, no fuel its ok, otherwise the diaphragm is leaking causing rich running.

This site is full of clueless conjecture.As is any group of people, on nearly any subject. There is the odd very helpfull and insightful post that will get a bike back on the road.

Like this one of yours.

My only suggestion is.. that fuel evaporation has left some of that 'varnish type' residue inside an/the injector system????

[Mokadah]

I blame the government

[gammaguy]

This site is full of clueless conjecture.

never let the use of good basic mechanical facts get in the way of a nicely drawn out thread that will keep someone entertained for possibly weeks.

[GrayWolf]

I am full of clueless conjecture.

there fixed it :D

[Katman]

there fixed it :D

Did I hurt your feelings the other day?

[imdying]

This site is full of clueless conjecture.I have this need to rep you for being an unhelpful prick, but that's offset by the fact you're correct.

Start with your brothers suggestion, then followed by steve_t's, then BassMatt's. Coil on plug testers are pretty common/cheap these days, you should be able to find one to borrow/abuse. Assuming you've replaced the fuel with fresh.
