zx9r e starting help needed.

[ryder2012]

hi guys,

sorry to jump straight into the workshop but i have a problem with my 02 zx9r e model.

she's been sat for sometime and now its come to trying to get her started.

Basically it sounds like shes good to start but just isnt firing up. you can hear shes trying but i think the carbs may be blocked.

i've put fuel directly into the carbs and she'll fire up till that burns off then goes back to almost starting but not quite there.

heres a video of the bike trying to turn over.

I've had the tank off, stripped out the fuel lines, pump and given them all a clean off. pumps pumping fuel just fine, as i've said, the engine will fire up with fuel direct to the carbs. battery is all good.

I dont have the mechanical expertise to remove the carbs, strip and clean them.

I was wondering, if by chance the carbs are blocked that someone might be local with the technical knowledge to be able to offer a helping hand with the task?

i know its a big ask but i need to get the bike back on the road asap due to a commitment coming up and i wasnt expecting this kind of problem.

thanks for the reply, the spark plugs look to be okay, i took them out and dont seem to be caked up or discoloured. well i took the 2 middle ones out as to remove the 2 outter ones the air ram pipes seem to need removing.

if the plugs was a problem then the bike wouldnt start up with fuel direct to the carbs would it?

(asking because i dont know so good practice to ask questions and learn)

I had held the starter for a longer period but all it was doing was killing the battery haha.

It would, my ZX7R is hesitating to start, it is due to old plugs, that can't ignite the fuel properly. To check that, buy starter spray (ether) and spray it into the ram air intake, it'll fire up with no problem.

But there's more to be checked. The valve clearances, air filter, the carburetors...

The starter spray (ether) will give you a perfectly combustible mixture (should be available in bike shops, but I'm not sure about that, as I'm not a UK-er).

The valve clearances, well you could do it by yourself, it's not complicated, but you are going to need a feeler gauge and bucket full of different shims (to change the shims in your head) and those are not cheap. People that do this regularly have buckets full of shims.

Carburetors, I do not think this will be a fueling issue, so I wouldn't touch them. But, in the video I can see that choke ON or OFF makes no difference, so I'd be checking the choke cable is actually engaging the choke. It could be as simple as that, cold engines don't tend to start well with no choke.

After watching that video the thing that got me was how long you were pressing the button for.

I have the same age Ninja and unless it has been out for a good long run..... there is no way in hell that it would ever start that quick.

My start procedure is something along the following lines:

Full choke, press start button with between 0 and full throttle and listen to the tone of the bike and adjust throttle as necessary...... if it doesn't start after 10 seconds I let go of the start button give it a couple of seconds and try again. Normally it takes 5-10 seconds on the start button though

OK just got a quick video of trying to start my 02 zx9r using the same method you were using.... and I was out on this about an hour ago:

I tried holding the button for longer. Pretty much the same. Took another video and will post it later on when attending work. Think the plugs might actually be part of the problem. 3 out of 4 was wet but not drenched but one was bone dry. So there bloat be an issue with one of the carbs problem is can't remember which head It came out of. Either 2 or 3.

[ryder2012]

Heres the video of the starter button being pressed for longer.

I tried it full throttle and pretty much every step between full and no throttle.

As before, i've pulled out the plugs now with the intention of putting in fresh ones tomorrow.

Will see how that goes tomorrow but any other ideas are more than welcome in the mean time.

Checked the coils last night. Sparks looked weak but was sparking. Going for new plugs a bit later today.
