ER-5 not starting

Hello everyone.

There was faultless performance from the ER-5 yesterday but this
morning when I set off for work at 07:30 the ER-5 wouldn't start.

It had half a tank of petrol, choke on full, the engine 'spun around'
or whatever it does when you press the started making the usual noises
but didn't get anywhere near idle or even plubbing around on its own.
The starter motor sounded fine. There were a few quiet bangs (or loud
pops) from the exhaust while it was trying to start. After 10 seconds
of it not starting I left it for ten seconds and then had another go,
and another. No joy. The Battery seems to have plenty of juice in it
as it wasn't slowing down.

I took the tank bag off and rolled it around aiming for the bottom of
the road, stuck it in second and it bumped first time. I picked up
the tank bag and set off for work.

I had to bump it again on the way home just now.

It's making all the right noises and bumps fine. Do you have any
suggestions? It's due for a decent service in a thousand miles.

 

In uk.rec.motorcycles, BGN belched forth and ejected the following:

Shit in the carbs

 

Surely that'll just make it messy to work on?

.... and this might seem to imply that you're getting too much fuel
into it now the weather has turned warmer (or has it?). The 'banging'
would be unburnt fuel in the exhaust igniting as it tries to fire, but
the combustion chambers are too flooded to burn cleanly.

Try only using half choke. Or if you've already got the problem, turn
the choke off altogether and see if it fires (it may start but not
idle, so some choke might be needed).

Why would it bump fine? That's the puzzling question. Possibly just
the fact that you're probably getting it to turn over at a different
engine speed than the starter is somehow giving it a better chance.

I've no idea. It bumped perfectly, first time. I'll try half the
choke tomorrow. I forgot about summer.

 

If it bumps with ease, but won't fire up on the starter, then the battery
isn't giving enough power to run the starter and the ignition system
together. Either a new battery or a period on the charger would seem
indicated.

It was making all of the right noises for the full 30 seconds I
pressed it (in 10 second chunks) and didn't seem to struggle.
Voltmeter gives a reading of 12.80v (after a ride) which would seem to
indicate the battery is happy. I'll give the choke idea a go
tomorrow.

 

BGN scribbled on the back of a napkin:

If it still doesn't want to go, check the voltage before you try to
start it tomorrow. 12.8 isn't that great but it should be OK(ish). If
it still looks like 12.8 tomorrow, check what it drops to when you're
cranking the engine - it may well drop too low for the engine to fire.

 

Exactly.

Nick,

Also check the connections on the low tension side of the ignition. Take
off and clean the feeds and any earthing points. Pay particular
attention to the signal wires coming from the crankshaft triggers - they
only pass milliamps and the slightest corrosion affects them badly.

I was with you all the way up to "also."

 

If you are in doubt of battery power: Connect a car with jumper start wires,
and try to start (yes, do duble check you put + on +, and - on - other way
round makes interesting fireworks, but is not adviced!).

If you can start on the car battery, your battery is either defective, or
not charged. Not charged is not really an option after having driven around
450 mls in the last 48h. So, maybe the voltage converter for charging went
out and gives off too much power into the battery. Simply only replacing the
battery would damage the new one quick as well, so make sure you check the
voltage output of the charger.


Another idea: The starter axle is pulled onto the main axle (whatever these
things are called, crank? crankshaft?) by a magnet. Listen very carefully to
make sure the starter is really engaged to the main axle, and not just
spinning free. You would hear the difference, since the starter turns a lot
faster if it cannot engage into the main.

Told you so.

I forgot what summer meant in relation to the choke lever.

 

You need the Book Of Lies for this. All you have to do really, is clean
the connections on the ignition system. Not the sparky side, but the
side that feeds it 12volts.
Not saying that this is your current problem, but a few minutes spent
doing this will avoid future problems in this area, which might leave
you stranded.

Apart from that, it's all to the good if you learn just a little bit
more of the bike's systems.

<Bangs head repeatedly on wall>

Nick, Nick, it might be a good idea to come up here some time with your
bike, and we'll give it a service, and show you the difference between
carburettors and camel shit.

Due to new EU regulations the use of camel shit in the manufacture
motor vehicles is no longer permitted. As a substitute one can, under
licence, use partially fermented horse shit as long as it hasn't been
obtained with the animal in a stressed condition.

 

LOL And I'm trying to shove my right eyebrow back down.

 

On Tue, 11 Apr 2006 19:46:03 +0100,

The shit is in the carburettors, the piss is in the tank.

 

I'd empty out the carb float bowls in case there is any water in there,
Is there a drain around the fuel filler cap, and is it working and not
blocked up? Is there a fuel filter fitted?
