She died...

[Jamrock]

NSR125, coming home from the gym did the usual of choke on for a couple of minutes while I suit up, gloves on and helmet on. Happily two-stroked on my way when shock horror she sort of died, I figured I had forgotten to fill her up with petrol like I've done previously but called Mummy who was down quick as a flash with a jerry can. Filled her up but couldn't start her, wore out the battery from trying so had to try and bump but still nothing. Left her there for the night and decided I had been defeated.

Any ideas what it could be? When I was trying to bump it the bike refused to rev and sounded sort of bogged down, a group of old guys walked past and one of them stated it sounded like it wasn't firing and a new spark plug should do it but I'm not so sure, the signs of no life seems to me like engine failure although by no means am I an expert.

So anyone have any ideas as to what could bring her back from the grave? I will be booking into the garage tomorrow but want to know how much I'm going to be looking at in repairs

Wouldn't hurt to try chagning that spark plug before you take it to the garage.

You didn't forget to fill it up with 2stroke oil?

The old boys might be right. The first thing to do is check the state of the plug, and check for a spark. Even if the plug isn't at fault, you might be able to determine what is wrong with it from the condition of the plug itself.

Obviously the oil ones don't apply to a 2-stroke.

if you ran it down to the bottom of the tank it would of washed all the shit swimming round the botom down through teh fuel tap and into the carb , give it all a good clean and it should be all good

[salty21]

it wouldnt have got as far as the carb as there is a filter thing attached to the tap, but that could need cleaning, my money is on the plug being fouled due to the ammount of choke you use, you should only really use the choke to get it started, then after about 10-20 seconds of the engine running gradually close the choke and it should tick over normal or slightly low on the revs, i found on my nsr the choke was only needed on the colder mornings and would start fine without a lot of the time. So in short, dont use the choke any more than you have to

Or the plug gap aint what it should be.
somehow my 50 used to do this to plugs ocasionally.
If the plug was fouled or gap was wrong it would start for about a second smoke alot and die.
just like yours is doing.

Ahh your not the only one, i was happily smokin along the a12 this evening and my bike just died after about 30miles of running absolutely perfect! had to get the breakdown van to take me home!

when i try and kick start it, it just sounds like its pushing air through, and no spark. havn't checked the plug yet but will take a look tomorrow!

Any luck with yours yet ?

[Jamrock]

Nah the guys at the garage can't collect it until Monday and in the mean time I've just been sat stroking her, crying a little inside. If she is dead though it gives me an excuse to take my A2 and get an SRAD or something. I just hope that it is something simple.

Cheers for all the advice guys!

my guess, is the spark plug is fouled from idling it with the choke on, it will be black with soot and so cant spark

you can either clean it or get a new one, and in future dont leave it on idle with the choke on
