Check the plug lead is firmly connected to the plug, with vibrations etc. they have been known to come loose.

Could be anything! Was it sleeping outside uncovered? Is the battery dead? Are spark plugs leads correctly connected as 528i mentioned?

Hey Guys,
Yeh It Was Uncovered OutSide For About 3 Months,
I Charged The Bat And Checked The Plug Caps Were On Fully.
AND IT FIREED UP!!! (once)
Tryed Again And It Just Turns Over For Ages Then Back Fired So Lould I Nearly Needed To Change My Underwear!!.
Now Thats All It Will Do
Oh And I Checked The Air Box Was Not Blocked Or Anything
I Need To Check The Plugs But I Cant Even Get My Plug Spanner Any Where Near Them!!!:mad:

Steffano2002

I'd say it's either electrical or fuel-related. Start by changing spark plugs. If you still have a problem then fuel filter change perhaps?

So what you're saying is you left it outside uncovered for 3 months and when you came back it fired up no problem. Then the next day it wouldn't even start? Is that correct?

Good point, other than electrical or fuel related it can only be bike related;)

No harm in changing plugs but I think it is overkill as a first option. Fuel filter change, why? - don't agree with this, doesn't make sense to me at all.

I could be wrong, but I've a feeling he means that a while back the bike was left out uncovered for a period of 3 months, but that it has been starting regularly since then. Then one happy :mad: day it wouldn't start.

For starters, don't turn your engine over and over in the hope of it starting. It should start after a second or two if its going to start at all.

Now that you got battery charged, and it did start once, it sounds as if you created another problem for yourself: that you've flooded your engine turning it over and over and not starting.So hit the stop / kill switch and turn the engine over a few times for 2-3 seconds at a go, with 20 second break between turnovers. Bike obviously won't start with kill switch on, but will help clear out excess petrol.

If you want at this stage you can take out your plugs and wipe them dry. No need to replace them at this stage. Put them back in, open your throttle FULLY (i know, it sounds wrong to open it fully, but there is a reason for it;) )
Leave choke off and try starting again as normal.

Now, does it start? (by the way, you didn't have the choke on in the beginning which might have caused your problem?? i'm sure you didn't )

And don't worry about a backfire or two as it starts, prob lots of unburnt fuel hanging around. Do worry if it starts and keeps backfiring.

One other thing, if its a case where you were starting it after a 3 month stint of non use, (you really need to sort this out:p ), and it began backfiring / not starting on the first few attempts after being lying up, try draining your carbs. You should see a drain screw on the bottom of the float bowls.

Give this a bash and let us know how you got on. If you could clarify the lying up period, if bike was running after this or not, we might be able to get to root of problem easier.

Ride safe!

First try draining the Carb float bowls. Next get a voltmeter and check the battery while turning over the starter. If the reading drops change the battery as it's knackered. Third change the spark plugs as they're probably too fouled up to be of use at this point. If the bike still doesn't run after this check it checked out.

ANY battery will show a voltage drop when running a load as big as the starter motor. It even happens with mains electricity if the load is big enough.

Pigeon Reaper

yep but if it drops below around 11 volts it's probably gone.

I don't know... I have a thing against them... They don't like me and I don't like them

Why bother measuring the voltage drop at all - if there isn't enough power in the battery won't you hear the engine turning slower than it should? Or is there another reason that i'm missing for checking the voltage when turning it over?

At a tangent ninja, i was wondering, if your neighbour was drawing a huge load, would the voltage drop in your own house? Or would it be more of a case that one house no matter how much power it was using (practically speaking ) wouldn't matter feck all to the ESB? So that there would have to be a heap of houses in the one area using lots of power before the voltage would drop? Then again, our lights go down when the power shower is put on......i'm a bit lost. Any sparkys or ESB men round

Do you mean gone beyond able to be charged up again Pigeon? Or just temporarily gone? I don't get why you'd need a voltmeter and the hassle of taking off seat (yeah I am a lazy bastard!) - can you get more from the meter as opposed to just turning it over and listening to the engine?

Good name Pigeon, kill all those flying rats !!

Right I Tryed The Folowing

Drained The Carbs Tryed The Kill Switch Thing (Engine Will Not Turn Over With It Off) Tryed To Start The Bike With Fuel Off (in Case Of Flooding) Checked All The HT Caps Where ON! Checked Fuel Was Getting In To The Carbs Checked The Air Box AND IT STILL BACK FIERS!!! And Wont Start!!! Im Going Insane!!! I Have To Ride A Sachs Madass 50! Till Its Fixed!!!

If you can check the battery and the voltage drops when turning over the engine to around 12V or under(you may get away with 11.5V) the battery will need replacement as it doesn't hold enough power anymore. IE it's worn out. This means that the sparks and speed of turnover of the starter motor aren't enough to fire up the engine. The plugs then foul up making matters worse. This is why new plugs will also be needed(you may be able to clean them but it's better to replace). The backfiring occurs due to petrol/air being pumped through the cyclinders and into the exhaust. This can be ignited by the odd spark firing resulting in backfires/soiled underwear. If in doubt change the battery and sparks to see if this fixes it. Used to happen on an old CB-1 I used. Even jumping the bike may not start it due to the fouling on the plugs. Also when changing the plugs check for spark on each of them. If they all spark and the battery has been changed it's probably the starter motor as fuel seems to be getting into the engine as evidenced by the backfiring. If you're not comfortable doing this it's probably a good idea leaving it into a shop.

Dead Petrol, make sure carbs are clean not just drained, petrol when left for a period turns into a sticky substance. check plugs by taking one out connecting it back to lead and earthing the side of it to the engine then turn over bike, should see a spark, failing all that check ignition pick up coil not sure about this on a bandit though. Good Luck

Ragz2009

hey Guys I Have Tryed Everything!!
Only Thing I Cant Do Is Check The Plugs Or Clean Them!! I Cant Find A Plug Spanner To Fit!!!

Any Idea What To Do!!!

Maybe it got clogged with exclamation marks!!!!!!!!!!!!!!!!!!!!

If you have flooded ( due to old petrol or whatever ) those particular plugs , they are usually never quite the same again , either it wont go at all or you will notice tiny misfires.

Ragz2009

yeh soz lol im going mad! lol

How The Hell Do I Get The Plugs Out Tho!?
Every plug spanner i have found wont do it and every shop i looked in didnt have one to fit!

bushy...

You need a thin wall plug socket usually , bike shops should have one .There is a n effort of one in the standard tool kit , you could try that .
Be careful you dont break the plug ( metal or ceramic bit) leads to more pain.

XDA2prisoner

if its anything like the old blades, you'll need a 16mm deep socket most good engineering shops have em, check on web to find size though

Hey Guys,
I Fixed The Bandit, I Got It Some New Plugs And A New Tank Of Fuel,
Drained And Cleaned The Carbs And Jets. Then She Started On The 2nd Try,
Was Very Smoky For About 30Secs Then Cleared Up And Now Runs A Dream.

Cheers For Every Ones Help.
Ragz:D

Pigeon Reaper

sounds like fouled plugs and bad fuel in the carbs if it's been sitting for a while. If it happens again soon you'll just need to check that it's not running too rich or that the battery isn't dodgey. The once the smoke cleared it was probably stuff in the exhaust burning off. Anyhow well done getting it running again. Always feels good to have fixed it yourself.
