250-500cc 2013 husky 300 cutting out

well my 2013 husky is having some electrical dramas its intermittently cutting out it sounds like its fouling a plug when its doing it,im thinking its something to do with the coil as i have taken my kill switch apart and sprayed it out with inox [water dispersant] but its still doing it. anyone had similar probs or knows where to look?
cheers

Check your plug cap.Mine was bad so replaced with a NGK cap.

and the earth point on the frame for the coil

I just got done dealing with the same issue,(2012wr300)Unplug the harness from the coil and regulator and pull it out so you can see the whole thing.Mine rubbed though right where he u-bend is behind the coil causing it to short to ground on the frame. took me a while to find this,I even replaced the coil trying to find it.Good luck

you are spot on the money glenn mine is the exact same problem........how did you repair yours? i done a temporary tape job on the area just to test it, bike seems to run fine now but sometimes wont start by kicking it over but roll starts without a drama?

I just taped up each wire and then taped electrical taped the whole harness.(like 3 times). I don't have any starting issues though.don't know what to tell you on that issue.

no worries glenn i will pull her apart again and have another look,may tape her again and then get some of that electrical heat shrink wrap stuff around it.

well found out why it wont start now.....the cylinder is full of coolant bike only has 45 hours on it and its shit the head orings,and guess what husqvarna wont cover it under warranty as they said because it hasn't had a top end service at 15hrs! by a husky dealer so its out of my pocket. 15hrs seems extremely low for a top end service.this makes me angry.

I feel ya,my head o-rings failed at about the same. I was kinda irritated also,but $15 and 30 min later I was back in business.

while its apart im going to chuck a new slug in it,husky dealer said it has minimal wear but while its apart i may aswell do it

Did it overheat? Running lean? Just curious as to why the o-rings failed. I don't have an hour meter, but I'm sure I have way more than 45 hours on mine and when I recently took it apart the o-rings looked great and so did the top end.

no didnt overheat and jetting is pretty close to perfect.....so its got me stuffed

it becasue husky uses the wrong o-rings. they need to be high temp, not the black stuff. the black rubber was never meant to seal compression or fire!

you can get high temp o-rings from a local hydralic shop.

husky cuts so many corners on these bikes its rediculous. or if youd like to putt he same wrong parts back in that failed the 1st time you can buy the black o-rings for around $5 at any hardware store around.

really?? then they should fix it under warranty then and put the correct ones in it.

if they admitted they have a problem.

like i said, try and get yourself a set of high temp o-rings. youll be out labor and a couple bucks but dont put the stock black ones back in.

I Done 100hrs on my wr300 2010. Head never come off. Didn't have a problem?

That's funny the black o ring on my exhaust pipe where it come out of the cylinder hasn't failed
They do make black hi temp ones

i used the green ktm o-rings in my wr. ive used the black ones before but the green ones do last longer. another thing i like to do is used the copper permatex silicone thats for exhaust on the orings for lube and for longevity.

my 2012 wr300 had a faulty stator from new that was fixed under warranty.foot breaking kick back & hill /push start impossible 50% of time
