Fricking bike wont start!!

[cheese]

OK BKE IS A rm 250 (96)

I've cleaned the plug, air filter, adn carb out.

if it does start it will run for about 5 - 10 secs, then die.

the gas is about 3 weeks old that is sitting in it, but that shouldn't make it die if it's running should it?

My leg feels like jelly now......

I'm off to the speedway!!!!

[trx400ex]

have you checked your filter in the fuel tank/line or maybe theres water in the tank from washing it last time.
try replacing the plug(cheap investment,i fell for that one:slap: )it may be a dud.
maybe the plug cover cracked,shorting on the head?
if all else fails hit it with a hammer:bash: ,wont fix it but youll feel better:blip:

[cheese]

Yeah teh plug was fouling a bit. So I cleaned it up and it was a nice big blue spark.

I'll drain teh gas and see how it goes wioth some fresh stuff.

teh plug is as good as new and only run about 5 hours

[skidMark]

id still check over your carby again i had the same prob with my tzr just turned out both carbs had the smallest little bit of crap in them cleaned that out and it fired straight up no problems since ....

usually with these sort of things it is a fuel problem as with most problems with bikes.....throughly check it has fuel...check carbs and check spark ..general rules really then you start getting into the tricky stuff

so yeah id just double check those carbs mate because mine wasnt filling the bowl fast enough so the tiniest bit would go in it would use that then die then by the time you fired it up again it had got a little bit in it enough to just get it started and so on so eventually pulled the carbs to pieces cleaned them out extremely throughly(ok so i can't spell lol) and it worked fine ...

drain some fuel out your carb bowl drain and see how much comes out because it may be filling the bowl too slowly ...thats the easiest way to check before you goto the hassle of pulling it to a million pices

also check your fuel tap hasnt got same crap blocking it's flow very rare but it does happen because gunk can sometimes seap through the in tank filter

hope something in that can help you out

I've found that if you start looking at new bikes then your old bikes senses it and starts behaving properly again. Might be worth a try. ;)

[cheese]

Cheers for the replys guys! I'll get into it tomorrow.

Also another funny thing. I had teh clutch replaced, but now it's like it won't disengage porperly. I't like it's tooo good.

Rooted springs??

[cheese]

oh yeah I should say too, that it's being a real wanker to start as well. I have to kick it over about 30 times to get it to go (when it feels like going) and then will run for 5-10 secs.

I'll do teh fuel tomorrow and see where that gets me....

[T.W.R]

try cleaning the carb again as suggested above, but check for blockages in either the pilot jet or emulsion tube.

if your getting through a few plugs & they seem to foul quickly, what heat range are you running ? you could have too colder grade plug in there

[2much]

Cheese, grow some balls and stop tryin to kick start it like a girl!!! or perhaps you'll see the light and trade it for a road bike???

just kiddin mate, sounds like the fuel filter or something is restricting fuel flow?

Have to catch up for a beer some time mate. c u.

[cheese]

cool will do tomorrow. Now wanting to get another $40 plug though......

Cheers guys you top blokes!!:banana: :2thumbsup

[cheese]

is that you mark?

When you next in town.

Road bikes, mate you scared of teh dirt or somethign?

[2much]

Yeah mate it's me, coming up on wednesday till friday or saturday...

Mate, gravel tastes better than dirt, and you don't get to eat it as often.... hopefully

[2much]

Having a drink with Lucille (do you remember her?) at the masonic on thursday arvo if you're keen

you know how you were told the bike was a 98 and its a 96, you didn't by chance buy it off the scamster Rachell011 on tardme. that trader is constantly advertising bikes about 3 years newer than they are

on topic, it does sound like fuel, check your carb vents are not blocked and theres not a bit of shit stuck in the needle valve, a way to test if its defiantely fuel is spray engine start into the air filter once u get it running, it should run until you stop spraying.. if it still cuts out its not likely to be fuel

[cheese]

Mattyc, Na it was some guy Carl from out east tamaki way. I learnt alot with that one....

Mark, I'm out of town most of teh week so probably no good. Sorry buddy.

[cheese]

Ok I just pulled ALL of the carb appart and cleaned it out.

I'll try starting it again tomorrow, I'll get a new plug too.

here was a funny thing though. The plug was a bit wet after I kicked it over a few 100 times, and when I tried to test it, teh spark kind looked like it was down inside teh plug.... strange.....

That plug is stuffed.

[cheese]

man it's only run for about 5 hours!

[cheese]

Ok It seams my bike eats spark plugs, It's kinda anoying too!!!

So is it a case of too rich or lean? or just the way I ride?

[bugjuice]

my bike eats tyres.. sucks, huh?

depends on how it's eating the plugs, which will show you what your issue is..
do they get fowled to quick? do they burn up quick? do they crack..?? You using the right plug for the bike?

[F5 Dave]

Usually too rich,

but where? is the question to ask. If you are trail riding then chances are the pilot jet & it fouls when putting around. Unless you are wide open for extended periods it is safe to go to the next hotter plug than std.

Good idea to check the plug cover to see not more than 7k. A slightly weak ignition may be an issue.

[Mattyc]

what color is your plug and what oil are you using in your premix, my KTM kills plugs randomly, but they seem to die after the bike has sat for a little bit, never when i am riding it, my friend has a kx that if you are not careful it will foul a plug in the first few mins of riding, and will cut out, trick is to keep it running

[cheese]

Guess what, the plug was stuffed.....:brick:

that is the third one!!

Apparently I don't ride my bike hard enough.... and it's too rich.....:slap:

[cheese]

yeh I ride too slow apparently, so it's fouling adn rooting it....

I'm going to get it jetted.

[KLOWN]

My bike went through 3 plugs in two weeks. I found the plug cap was rusting away so there was enough spark to run the bike but when I was warming it up with the choke on it would start to foul the plug. If i turned the bike off after warming it up but not taking it for a ride I wouldn't be able to start it again until I cleaned the plug. So, check the plug end caps, also I switched from a standard ngk plug to an iridium one and that made a world of difference. It didn't get fouled even though I hadn't changed the cap yet. I have since bought new plug cap ($7) and haven't had anymore fouling problems. Sorry about the long winded reply:slap:

[skidMark]

take it to a bike shop get thme to get it running the correct mixture and then try find some decent plugs that do'n't cost you an arm and a leg

then if they still screw out you can replace them cheap enough..

go see laurie at panmure motorcycles in morrin road panmure he will probably know why it's stuffing plugs..

Never ever risk using cheap plugs in a two smoker (unless the manufacturers recommendation is a cheap one - sometime is). And always replace the plug as a matter of course if you're having any engine problem at all.

[Ixion]

Yup, that'll do it. Wring its neck.

[Ixion]

It's a two smoker. it's gonna eat plugs. Deal with it. Just carry a few a spares (tuck 'em inside a frame tube.). And it's the way you ride, you've been letting the revs go below the red line haven't you. Too rich if they're fouling and crapping out, too lean if the electrodes are disappearing (though usually the piston follows soon behind)

[Motu]

The previous owner could have set it up richer to suit his riding,and been able to keep the plug clean.You may have to lean it out to suit yourself.I don't have a clue about such finese,but first see what rev range it seems to run richest at and work from there.Most likely richer on bottom end to get more snap out of turns.

[F5 Dave]

Having a think about this in the weekend. One, check the tank tap doesn’t leak, (you do turn it off yeah?) this could be filling your crank cases up & fouling your plug first time you kick it after leaving it a while.

Use the choke when cold, but don't open the throttle until it starts as you are negating the choke cct by rushing a bunch of air past.

Also the RHS crank seals apparently don’t last long on RMs of this vintage. This will tend to foul plugs. May be able to change this in situ if it is outside the bearing, some suzis aren’t though.

[cheese]

Well it did it agian. I rode it harder and it still fouled a plug adn rooted it. One thing though factory plug is a 10 (seems high) and it came with a 7, I put the old 7 back in it and it went sweet as. maybe it's just set up to run that plug?? I'll see how it goes.
