are you using the choke... sometimes when cold mine will fire then die right away if that happens i have to crank it over for 10-15 seconds sometimes then it will fire... turn the choke on before you start it and see if that helps...

doesnt seem to make any difference choke or no choke.

I cranked it over for another 3 minutes with every possible configuration of choke/throttle/fuel tap position I could think of and I still couldnt get it to do anything but backfire.

Im going home in a minute to try another fuel pump on it.
Ive got one hanging about somewhere.

It seems to be fuel related.

The mechanic dude reckoned to try jumping it as a low battery voltage can stop them from firing easy.

I will also try this

Hi.

Ive just got myself a 95 ZX6R which I am having a bitch of a time getting started when the bike is cold.

It fires instantly then dies.

It will then wind over with bugger all sign of starting, except it
will backfire loudly out of the exhaust.

If you leave it for a few hours it will fire again and do the same thing.

My local bike mechanic is booked up for 2 months solid so I need some
help to get this thing going.


It starts perfectly when its warm.

Im suspecting the fuel pump?.. anyone else got any ideas???????

Tried a different fuel pump. no different
It definatly has fuel in there and under pressure....

Also tried jump starting it from my car (running)
no go either....


looking down the carbs I can see when it backfires its always in
no. 3 cylinder.

The honda dealer is looking at it now for me..
Its driving me nuts........


I also have a feeling thing are about to get expensive...........

I get a huge backfire if I try to start mine when dead cold with the choke on. I have to fire it up first then immediately hit the choke.

Mind you, this morning I'd just pushed it back out of it's little corner and it gave a smaller pop out the exhaust, thinking I might have rolled the throttle slighly when I was pushing it back.

It's not the speed that kills, it's the sudden stop...

find out tommorrow no doubt. They didnt get time to look this arvo.

Im wondering if I got a dodgy tank of fuel as its been quite good up until this morning, Its been a turd to start, but it has always started.

This morning all it wanted to do was scare the neighbours @ 6am by
backfiring.

I couldnt get it to run at all.

i have a '96 which basiclly the same bike and had exactly the same problem. i had the carbs cleaned and set up right as they where totally full of crap and also had the choke adjusted. now it starts first time every time (ok some on the 2nd go!). cost me a $150 aussie to get it done by Dyno-Bike here in Brissie.

When I bought my 95 a couple years ago it had some carb problems too. Had it straightened out and it works great now!

Step 1-Twist handle
Step 2-Hold on!

ok its all fixed

2x fouled plugs due to a corroded electrical connetion on one of the coils.

they synchronised the carbs and adjusted the choke.

New plugs
