XR sparking problem

Not a 600 but a 250 but just hoping to get some idea`s.

 

A mate of mine has an old XR 250 which after putting away in the shed for 8 weeks will now not start.

 

The problem seems to be that he can`t get a spark any further than the end of the bare HT lead when grounded to the engine.

 

We have tried different plugs and caps but cannot get a spark at the plug.

 

Any idea`s gentlemen ?

 

Cheers Bob.

Just because it will fire from a bare lead to the ground does not mean it has the power to travel through the resistor in the cap and ascross the spark plug gap........

 

Is this a kick start AC voltage bike.does it have a battery.and what year is it.you are not makin it easy for us..

Opps sorry,

 

It`s a 1988 kick start bike with no battery,

Then look at the stator as the usual cause on these older bikes.........it feeds the current needed to fire the plug..seems that what you are saying is it will fire,but not enough to jump the plug gap..

Ok ta,

 

I know how to check a stator on a running bike eg to check the charging but how do you check a stator on a none running bike ?

Edited by xbakerbob

that.........you need a manual for to check with a multi meter......for resistance and output voltage..

Just to let you guys know it ended up being  the coil.

 

Now the bike starts and runs better than ever before.

 

Cheer`s Bob.
