this ones for a mate.
he has a 2002 Husky WR250 that is fouling plugs on trail rides. its fine when the tracks are open and flowing, but as soon as it gets tight and twisty and you can't open the throttle up it fouls plugs after about 20mins. plugs are wet and oily. bike runs strong when reved doesn't miss at all and does not blow any smoke. oil ratio is 40:1 Motorex, its been happening on the last 4 rides so cannot be dodgy fuel as fuel was fresh each time.
what he has checked.
carb all ok.
air leaks from magneto side ok. would appear not to be a gearbox side main seal as it does not blow smoke and pulls hard when reved.
reeds ok
no coolant leaks
what we assume its not
electrics as its very easy to start, runs well and will pull 140Kmh in top gear (surely that a good sign of healthy electrics)
piston/bore, as had a rebuilt top and bottom end about 6 rides ago, no problem till recently
Any clues guys?
-
Has the bike just started doing this or has he just aquired it Hoony (the bike that is)?
-
He has had the bike since new in 2002 RossMeister, only just started doing this.
that will teach him to buy a Hucking Pusky :D
-
Is it running ok down low and then fouling or running like the total true puss bucket that it is and then fouling? :-\
-
A too cold a plug, drop to an 8 heat range if he's running a 9.

its running good down low and fouls after time, when you get to a area when you can open it up like a fire break or road and give it the berries it does not clear and will foul.
-

standard heat range is 9 i think, he ran out of spare plugs when i was with him and we used a new 8 from my spare for the KTM, it fouled after time as well.
-
Are you sure everything is ok in the carb?
-
Nice bikes, v high strung.
change the engine seals and put a kit through the carb and check/change any induction rubber parts.
Do plug chop, i think its sucking air
-
it will be the ignition for sure
common on 250s and 360s
usuall first sign is fouling plugs
stator faulty
forget about how it has spark and starts
that will be the problemo ;)
-
G'day Russell,
how can you be so sure about the ignition, is it a common fault with huskies or have you had a similar problem on other bikes?
is it a weak spark at low revs problem and stator insulation breaking down?
-
thats exactly what it is and i have struck this
on 250 and 360 huskys
pull of the stator flywheel cdi and coil
send it all to bert at rewinds in vicco
he can test the whole system for a good price
then fix it if it is needed ;)
-
This is quite similar to the way my WR360 died. Sometimes it would run like a rocket, other times it would just flame-out for no apparent reason.
Always started easily, up until it really dropped its guts...
EVERYONE said "Yep, its the stator" when I told them the symptoms.
-
Good luck sending it to Bert at Small Coil Rewinds :o. Hopefully he'll get it right, hopefully......

i used to use jack at city auto electrics in coburg
he was very good but he has got a bit expensive
charged me $400
to rewind a canam stator ::)
who do you use michael
cheers rusty ;D
-
Thanks Russ, i too am interested in who you use Big K ?
everyone i have spoken to reckons Bert is a Curmudgeon.
-
I use Rohan at COD rewinds in Chiltern, never a problem always a great job. Maybe I'm being hard on Bert. He is obviously set in his ways, but after rewinding a Husaberg stator 3 times to no avail, I politely asked what settings he was using for the SEM. He was winding the stator to 1700 ohms which is KTM settings, not Husaberg which need to be wound to 3000 ohms. At 1700 ohms Husabergs will kick start, but not electric start. He refused to be told that he was winding them wrong and actually told me to get f%$#ed, sell it a client with a kick start bike and leave him alone! Now maybe he was having a bad day but I was HIS customer and that's how I was treated. He also refused a credit or refund so my experience see's Bert as an arrogant old prick to whom I will never send anything or recommend to anyone. Rohan on the other hand took the knowledge on board and now winds the best Husaberg stators in the land. I have sent everything from Husaberg, DT1 to Bultaco Motoplat and all have come back perfect.
Cheers,
K

I can also recommend Steve at Betta Bikes in Hackham South Australia. Top bloke and good turnaround.
-
My 360 WR 02 does the same . I've been told the needle in the carb is worn ?
-
Looks Like Holeshot Buddy was correctamondo, $200 for a rewound stator, my mate will test bike tomorrow before our October trial ride.
just for info, he rang Rohan at COD rewinds in Chiltern and was quoted $300 , Berty from small coil rewinds in Geelong did the job for $200. time will tell once he reports back to me.
-
cool keep us posted hoony ;D
-
Did you work out what is wrong with your wr 250 . Jeff
-
Hi, Fixed my 360 with a new needle, the needle is a husky made item you can't get one from mikuni. It's $27.00 so cheap to try first. Jeff
-
Did you work out what is wrong with your wr 250 . Jeff
Yes, my mates WR250 is ok now.
Thanks to Russel (Holeshot Buddy) for the heads up on the stator, it indeed was the problem. our trail ride is next week out the back of bushfire affected Marysville (Stockmans).

no worries hoonster anytime
even know a bit about hondas ::)
-
Has anybody checked how old your oil is had exactly the same problem with a 96360 turned out oil was no good
