1986 klf300 bayou A1

Hi guys my bayou just stopped going the other day,I put a new plug in but still did not go,then all a sudden it went so I used it for about 30 minutes and it ran perfect.Now it will not start again,I have been trying for the last 2 days.I have checked all the electrics,it has plenty of spark,plenty of fuel,the valve clearances are good.It turns over fine just will not fire.Tomorrow i am goint to check the set up timing(i think thats what is called)If thats not it there is only compression left as I don,t have a tester I put my finger over the plug hole and it popped my finger so there is copmresion there maybe not enough though.

I checked the timing today and it looks ok so now I am stumped.Any ideas would much appreciated.

is the spark brilliant blue or dim ?

[steve50]

The sparks is not brillant blue,its more bright white.

plenty of fuel in the tank. I take it that the fuel is getting to the cylinder

[steve50]

Yea plenty of fuel, I got a mate to have a look and he said there is not enough spark and what spark there is is irratic so monday I will go out and get a coil and hopefully that will fix it.

if it isnt the coil, it will be the stator im sure ... older bike and its probably worn out. same thing happened with my 1991 big bear ...

[steve50]

Thanks oxi but i think i found the real problem the spark plug hole thread is stripped, and as i have working on this i have found a lot of bolts that have been stripped so i think its time to scrap this lemon and spend a bit of money and get a good one.

[oxidized_black]

too bad ... a heli coil for the plug and a tap and die set for the stripped out threads can go a long way ...

[steve50]

Yes you are right but this bike has been nothing but trouble for me since i got it just 6 months ago and it has tested me to much,my own fault for not checking it out properly before buying.:-)

[steve50]

well I have decided to get a heli coil and see if I can get this bi*** going,this maybe a silly question but besides the mounting and as long as they have 2 pins are all coils the same for quad bikes?

[oxidized_black]

i would take the plug with you to ensure its the right fit for it ....

[steve50]

I got another after market coil today plugged it in turned the ignition on pressed the start button.......poof one destroyed coil,time to re-asses.
